Are you sourcing R-290 commercial refrigeration equipment for the EU, Gulf, or CIS market? Trying to figure out whether propane refrigerant is actually safe, compliant, and worth the regulatory headache?
Let me save you the suspense. Yes. R-290 is the 2026 default for self-contained commercial refrigeration. The short version is easy. The honest version takes a minute.
The short version: propane has a GWP of 3 (versus 1,430 for R-134a and 3,922 for R-404A), runs 5-8% more efficiently, is not regulated under EU F-Gas quotas, and is approved under EN IEC 60335-2-89:2022 with a 500-gram charge limit per circuit. That is the entire pitch in three lines.
The honest version: everything below. I lead export sales at Yichuhui, and this guide walks you through the chemistry, the regulations, the safety class, the energy savings, the OEM/ODM requirements, and the questions B2B buyers actually ask before they sign a purchase order. Not a sales pitch. Just the data I wish I had when I started selling hydrocarbon refrigeration.
The longer answer requires a closer look at chemistry, regulations, safety classes, and the practical realities of OEM manufacturing. If you are sourcing from a private-label or contract manufacturer, our OEM/ODM commercial refrigeration guide covers sourcing, certification, and quality-control essentials in depth. This current article draws on Yichuhui’s two decades of producing R-290 beverage merchandisers, display freezers, multi-deck open merchandisers, and ice cream display freezers for export markets—and the actual production-line decisions that determine whether a unit is compliant, durable, and safe.
You will learn the chemical and thermodynamic properties of R-290, how it compares head-to-head with R-134a, R-404A, and R-600a, which global regulations are driving adoption, how the A3 flammability classification affects charge limits and certification, the real-world energy savings, the OEM/ODM manufacturing requirements, and the questions B2B buyers most often ask before placing an order.
Key Takeaways
- R-290 (propane) has a GWP of 3 (IPCC AR5 100-year values), making it 99.8% less climate-impacting than R-134a (GWP 1,430) and 99.9% less than R-404A (GWP 3,922) under IPCC AR5 100-year values. For a deeper dive into the operational and commercial benefits, see our R-290 benefits guide for commercial refrigeration.
- The 2022 update to EN IEC 60335-2-89 raised the charge limit for A3 refrigerants from 150g to 500g per circuit in self-contained commercial equipment, opening the technology to most reach-in coolers, beverage merchandisers, and ice cream display freezers in the EU.
- R-290 is not an F-gas and is not subject to EU F-Gas Regulation 2024/573 phase-down quotas, making it a “future-proof” choice for OEMs and buyers with multi-year product roadmaps.
- Field-proven energy efficiency is 5-8% better than R-134a in matched-capacity tests, with the gap widening to 10-15% when paired with variable-speed compressors and electronic expansion valves.
- Yichuhui has manufactured R-290 commercial refrigeration equipment for 20+ years at its integrated facility in Zibo, Shandong, with a dedicated hydrocarbon charging line, hydrocarbon-trained technicians, and CE / EAC / GCC G-Mark certification on its product range.
What is R-290 Refrigerant in Commercial Refrigeration?
R-290 is refrigerant-grade propane (chemical formula C₃H₈), a saturated hydrocarbon that belongs to the same family as R-600a (isobutane, C₄H₁₀) and R-1270 (propylene, C₃H₆). It is classified as a “natural refrigerant” because it occurs in crude oil and natural gas and is not synthetically manufactured. To meet refrigerant-grade purity, R-290 must be at least 98.5% pure propane with moisture content below 100 ppm (per the Chinese HG/T 4632-2014 standard and AHRI 700).
Chemical and Thermodynamic Properties
R-290’s thermodynamic properties are the reason it outperforms HFCs on energy efficiency. Here’s the data:
| Property | Value | Engineering Implication |
|---|---|---|
| Molecular formula | C₃H₈ | Saturated hydrocarbon, no chlorine or fluorine |
| Molecular weight | 44.10 g/mol | Light molecule, fast vapor flow |
| Boiling point (1 atm) | -42.1 °C (-43.8 °F) | Suitable for medium- and low-temp applications |
| Critical temperature | 96.7 °C | Wide operating envelope |
| Critical pressure | 42.5 bar | Moderate, similar to R-22 |
| ODP (Ozone Depletion Potential) | 0 | No ozone impact |
| GWP (100-yr, IPCC AR5) | 3 | Negligible climate impact |
| ASHRAE 34 safety class | A3 | Lower toxicity, higher flammability |
| Autoignition temperature | 470 °C | Standard electrical components safe |
| LFL (Lower Flammability Limit) | 2.1% by volume | Charge limits critical |
| Oil miscibility | Excellent with POE and mineral oils | Standard compressor oils compatible |
The boiling point of -42.1 °C is the single most important number for refrigeration designers: it means R-290 can achieve evaporator temperatures down to roughly -35 °C in a single-stage system, covering virtually all commercial refrigeration needs from beverage chillers (+2 °C to +10 °C) to frozen food storage (-18 °C to -25 °C).

A Brief History
R-290 is not new. Propane was one of the earliest refrigerants used in the 1930s, before the introduction of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) in the 1950s. Once DuPont’s Freon family (R-12, R-22) and later HFCs (R-134a, R-404A) entered the market, hydrocarbons were largely abandoned in commercial refrigeration—mostly because the industry was not equipped to handle flammability, not because the refrigerant performed poorly.
The 1987 Montreal Protocol banned CFCs and HCFCs due to ozone depletion. The 2016 Kigali Amendment extended the phase-down to high-GWP HFCs. As HFC prices climbed and regulations tightened, R-290 returned to commercial refrigeration in the 2010s, accelerated by compressor manufacturer investments in hydrocarbon-compatible designs from leading compressor suppliers (variable-speed reciprocating and rotary platforms purpose-built for A3 refrigerants).
By 2026, R-290 is the default choice for new self-contained commercial refrigeration in the EU, GCC, and most regulated markets worldwide. China, India, and Brazil are transitioning production lines in parallel.
R-290 vs Other Refrigerants in Commercial Refrigeration: Detailed Comparison
Selecting the right refrigerant is the single highest-impact specification decision in a commercial refrigeration project. The table below compares R-290 against the three most common alternatives on the metrics that matter to B2B buyers: environmental impact, efficiency, safety, charge limits, and total cost of ownership.
R-290 vs R-134a
R-134a (1,1,1,2-tetrafluoroethane) was the dominant medium-temperature commercial refrigerant from the 1990s until the early 2020s. It is non-flammable (ASHRAE class A1) and easy to handle, which is why it remains popular in retrofit and service applications. However, its GWP of 1,430 places it squarely in the crosshairs of EU F-Gas Regulation 2024/573 and the Kigali Amendment phase-down. Safety classifications referenced throughout this guide follow ASHRAE Standard 34-2022.
For commercial refrigeration, the R-290 vs R-134a comparison is the most common decision point:
| Property | R-290 (Propane) | R-134a | R-290 Advantage |
|---|---|---|---|
| GWP (100-yr) | 3 | 1,430 | 99.8% lower |
| ODP | 0 | 0 | Equal |
| ASHRAE safety class | A3 (high flammability) | A1 (no flame propagation) | R-134a safer to handle |
| Energy efficiency (matched capacity) | Baseline | -5% to -8% vs R-290 | 5-8% better |
| Charge limit (self-contained, EN IEC 60335-2-89:2022) | 500 g | No limit | R-134a more flexible |
| Regulatory status (EU 2024) | Not F-gas, no quota | Subject to F-Gas phase-down | R-290 future-proof |
| Cost per kg (2026 bulk) | ~$2-3 | ~$8-12 | R-290 ~75% cheaper |
| Suitable for low-temp (<-25 °C) | Yes (single stage) | Marginal | R-290 better |
| Recyclability | Easy, low-cost | Requires specialized recovery | R-290 simpler |
Practical takeaway: If you are designing new self-contained commercial equipment for the EU, Gulf, or CIS market, R-290 wins on every metric except handling safety. R-134a only remains a rational choice for very large remote systems where charge size exceeds 500 g per circuit.
R-290 vs R-404A
R-404A is a zeotropic blend of R-125, R-143a, and R-134a designed for low- and medium-temperature commercial refrigeration. It has been the workhorse for supermarket freezers and ice cream display cases for over two decades—but its GWP of 3,922 makes it the highest-impact HFC still in widespread use. EU F-Gas Regulation 2024/573 bans the use of refrigerants with GWP ≥ 2,500 in new commercial refrigeration equipment from January 1, 2026, and bans service use from January 1, 2030.
If you’re retrofitting from R-404A (the legacy supermarket refrigerant), the differences are stark:
| Property | R-290 | R-404A | R-290 Advantage |
|---|---|---|---|
| GWP (100-yr) | 3 | 3,922 | 99.9% lower |
| Efficiency at -25 °C evaporator | Baseline | -8% to -12% | R-290 better |
| Temperature glide | 0 °C (pure) | ~0.7 °C | R-290 simpler design |
| EU 2026 ban on new equipment | No | Yes | R-290 compliant |
| EU 2030 service ban | No | Yes | R-290 serviceable long-term |
| Suitable for self-contained units | Yes (hermetic) | Limited (typically remote) | R-290 better suited |
Real-world example: In 2023, a Belgian supermarket chain converted 280 medium-temperature display cases from R-404A to R-290. The OEM reported 9.2% lower electricity consumption per unit, a refrigerant cost reduction of €38,000 across the fleet, and zero reported safety incidents over 18 months of operation. (Source: naturalrefrigerants.com case study, 2024.)
R-290 vs R-600a (Isobutane)
R-600a is the other hydrocarbon refrigerant that has gained traction, particularly in household refrigerators. Both R-290 and R-600a are A3-class hydrocarbons with GWP of 3. The difference is in boiling point and capacity: R-600a boils at -11.7 °C (vs -42.1 °C for R-290), making it better suited to high-temperature applications like domestic fridges and small wine coolers, while R-290’s lower boiling point opens it to medium- and low-temperature commercial use.
R-290 and R-600a (isobutane) are both hydrocarbon refrigerants. Here’s how they compare:
| Property | R-290 | R-600a |
|---|---|---|
| Boiling point | -42.1 °C | -11.7 °C |
| Best application | Commercial chillers, freezers, display cases | Domestic fridges, wine coolers |
| Capacity (matched displacement) | Higher at low temp | Lower at low temp |
| Charge limit (EN IEC 60335-2-89:2022) | 500 g | 500 g |
Why R-290 Wins on GWP
The climate math is brutal. As an illustrative example: a typical self-contained commercial unit charged with R-290 would release the equivalent of just a few kilograms of CO₂ if the entire charge escaped to atmosphere. The same unit charged with a typical HFC service charge releases orders-of-magnitude more CO₂ equivalent. In a 100-unit fleet, choosing R-290 over R-134a cuts lifetime refrigerant-related CO₂e by roughly 99%—the single largest environmental decision a buyer can make on this equipment category.
This is why EU regulators, U.S. EPA, and procurement officers at multinational retailers are mandating R-290 transitions.
Global Regulations Driving R-290 Adoption
R-290 adoption is not driven by environmental preference alone—it is driven by hard regulatory deadlines with financial penalties for non-compliance. Below is the regulatory landscape for the markets Yichuhui serves.
EU F-Gas Regulation 2024/573
The revised EU F-Gas Regulation 2024/573 entered into force on March 12, 2024, replacing Regulation 517/2014. It accelerates the HFC phase-down schedule and adds new bans on commercial refrigeration equipment using high-GWP refrigerants.
- HFC phase-down quota: 2024 baseline reduces to 55% of 2015 consumption; 2026 = 35%; 2030 = 20%; 2036 = 15%; 2050 = 0%. (Source: Regulation 2024/573 Annex VII.)
- Ban on commercial refrigeration equipment with GWP ≥ 150: applies from January 1, 2026 for new equipment. R-134a (GWP 1,430) is fully banned in new EU commercial refrigeration from this date.
- Service ban on refrigerants with GWP ≥ 2,500: from January 1, 2030. R-404A (GWP 3,922) cannot be used for servicing existing equipment.
- R-290 status: Not an F-gas. Not subject to quota. Not subject to equipment bans. Approved for use under EN IEC 60335-2-89:2022 with 500 g charge limit per circuit in self-contained units.
The bottom line for EU buyers: After January 1, 2026, R-134a is illegal in new commercial refrigeration equipment. R-290 is the legal, future-proof choice.
US EPA SNAP Program
The U.S. Environmental Protection Agency’s Significant New Alternatives Policy (SNAP) program has listed R-290 as acceptable for retail food refrigeration, commercial ice makers, and vending machines under Rule 20 (2015) and Rule 21 (2016), with subsequent expansions. The 2024 final rule (Federal Register, June 13, 2024) added additional use conditions and clarified charge limits:
- Retail food refrigeration (self-contained): R-290 acceptable with charge limit of 500 g per circuit.
- Ice makers (self-contained): R-290 acceptable up to 500 g.
- Vending machines (self-contained): R-290 acceptable up to 500 g.
(Source: EPA SNAP Rule listings and Federal Register notice 2024-11690.)
Kigali Amendment to the Montreal Protocol
Adopted in October 2016 and entered into force on January 1, 2019, the Kigali Amendment commits 197 signatory countries to an 80-85% phase-down of HFC consumption over 30 years. Developing countries (Article 5 Parties) follow a delayed schedule with a 2024-2026 baseline freeze and progressive reductions. The Kigali framework is the international treaty that underpins both the EU F-Gas Regulation and the U.S. AIM Act.
China, India, Brazil, and the GCC states are all Kigali signatories. The cumulative effect: the global HFC market is shrinking by design, and R-290 is one of the few large-scale alternatives with proven manufacturing capacity.
GCC and SASO Regulations
The Gulf Standardization Organization (GSO) and Saudi Standards, Metrology and Quality Organization (SASO) have aligned with the Kigali framework. Saudi Arabia’s SASO energy efficiency standards for commercial refrigeration (SASO 2874/2017) increasingly favor low-GWP refrigerants. The GCC G-Mark (also called GSO Conformity Track) for commercial refrigeration certifies products across all six GCC member states (Saudi Arabia, UAE, Kuwait, Bahrain, Oman, Qatar) and accepts R-290 under the same charge-limit framework as the EU.
Yichuhui’s experience: Yichuhui’s R-290 beverage merchandisers for the Saudi market have held GCC G-Mark certification since 2021. GCC G-Mark acceptance has become an increasingly common buyer requirement for new supermarket and convenience-store rollouts in the region.
China GB Standards and Hydrocarbon Adoption
China’s standardization framework treats R-290 as a mature, supported refrigerant:
- GB/T 19230.1-2020: Safety requirements for hydrocarbon refrigerants in household and commercial appliances.
- GB 4706.13-2014: Safety standard for commercial refrigeration appliances, harmonized with IEC 60335-2-89.
- HG/T 4632-2014: Refrigerant-grade propane purity standard.
China’s National Development and Reform Commission has included R-290 commercial refrigeration in its “Green Refrigeration” subsidy program since 2022, with rebates of 8-12% on certified equipment. This has accelerated domestic production capacity and reduced the cost premium for export buyers.
Safety Considerations for R-290 Commercial Refrigeration
R-290 is a highly flammable (A3) refrigerant. The safety profile is fundamentally different from R-134a (A1, non-flammable) and even R-32 (A2L, mildly flammable). For OEM/ODM buyers, safety compliance is not optional—failure to meet EN IEC 60335-2-89:2022 voids the product’s CE marking and prevents sale in the EU.
ASHRAE 34 Safety Classification: A3
The ASHRAE 34 classification system combines a letter (toxicity: A = lower toxicity, B = higher toxicity) with a number (flammability: 1 = no flame propagation, 2L = mildly flammable, 2 = flammable, 3 = highly flammable). R-290 is A3: lower toxicity but high flammability.
| Class | Flammability | LFL (g/m³) | Heat of Combustion | Example Refrigerants |
|---|---|---|---|---|
| A1 | No flame propagation | N/A | N/A | R-134a, R-404A, R-410A |
| A2L | Mildly flammable | > 250 | Low | R-32, R-454B |
| A2 | Flammable | > 250 | Moderate | R-152a |
| A3 | Highly flammable | ≤ 250 | High | R-290, R-600a, R-1270 |
The critical metric is the Lower Flammability Limit (LFL): R-290 becomes ignitable at concentrations of 2.1% by volume in air, equivalent to about 38 g/m³. The EN IEC 60335-2-89:2022 charge limit of 500 g is calibrated so that if the entire charge leaks into a small room, the resulting concentration stays below 25% of the LFL—the threshold for safe ventilation and ignition prevention.
EN IEC 60335-2-89:2022 Charge Limit and Safety Requirements
The 2022 update to the European harmonized standard EN IEC 60335-2-89 (corresponding to IEC 60335-2-89 Ed. 3.0) raised the maximum A3 charge in self-contained commercial refrigeration equipment from 150 g to 500 g per refrigerant circuit. This single change, ratified in 2023, opened R-290 to most reach-in coolers, beverage merchandisers, display freezers, and ice cream display freezers in the EU.
Mandatory safety features for R-290 units under EN IEC 60335-2-89:2022:
- Hermetically sealed refrigeration circuit — no field serviceable access, no flare fittings, only brazed joints.
- Self-contained design — no field-installed line sets; the refrigerant circuit must be factory-assembled and tested.
- Spark-proof electrical components — switches, thermostats, and relays rated for hydrocarbon environments.
- Leak detection — optional but increasingly required by end customers (methane/propane sensors with auto-shutoff).
- Forced ventilation — for built-in or enclosed installations, minimum airflow to dilute any leaked refrigerant below 25% of LFL.
- Yellow A3 label — visible warning sticker per EN 378 indicating the refrigerant and its safety class.
- Operator manual — explicit instructions on leak response, service procedures, and prohibited actions (no open flame within 1 m of the unit).
Yichuhui’s charging infrastructure: R-290 charging at Yichuhui takes place in a dedicated, mechanically ventilated hydrocarbon charging room with continuous leak detection, nitrogen-purged charging equipment, and intrinsically safe electrical fittings. The line is certified to GB 50058-2014 (explosion hazard design) and audited annually by an independent certification body.
Installation and Maintenance Best Practices
For B2B buyers, the safety responsibility does not end at the OEM. Installation and service require trained technicians:
- Service technicians must hold a hydrocarbon certification (e.g., EN 13313 in the EU, EPA Section 608 Type II in the U.S., or equivalent local credential).
- Recovery cylinders must be hydrocarbon-rated, and leak-checked before each use.
- Leak detection equipment must be calibrated for propane (calibrated to R-134a will give false negatives).
- Ventilation in service rooms and equipment rooms must meet EN 378 calculations based on room volume and charge size.
- No open flame, no smoking, no hot work within 1 meter of any R-290 equipment.
R-290 Energy Efficiency Benefits in Commercial Refrigeration
The energy efficiency of R-290 is its second-largest commercial advantage after climate impact. Real-world test data and field installations consistently show 5-8% lower electricity consumption compared to R-134a in matched applications, with the gap widening when R-290 is paired with modern components.
Field-Tested Efficiency Gains
Independent testing on R-290 versus R-134a self-contained commercial refrigeration units at standard EN 23953 test conditions (25 °C ambient, +4 °C evaporator, +32 °C condenser) confirms the efficiency advantage:
| Refrigerant | Compressor Type | COP | Directional Efficiency vs R-134a |
|---|---|---|---|
| R-134a | Fixed-speed reciprocating | Baseline | Reference |
| R-290 | Fixed-speed reciprocating | +5% to +9% | R-290 better |
| R-290 | Variable-speed (inverter) | +25% to +35% | R-290 + inverter best |
Why R-290 is more efficient: Propane’s thermodynamic properties—higher vapor pressure, higher latent heat of vaporization, and lower discharge temperature—reduce compressor work and improve heat transfer in the condenser and evaporator. The thermodynamic COP advantage is approximately 6-9% in typical operating conditions. A variable-speed compressor layers another 20-25% on top by matching compressor output to actual cooling demand.
Total Cost of Ownership: Directional Guidance
The 5-year total cost of ownership is where R-290 wins decisively. Since actual savings depend on local electricity rates, climate, duty cycle, and specific equipment configuration, the figures below are directional ranges based on industry benchmarks. Contact Yichuhui for a project-specific TCO model.
| Cost Driver | R-134a Fleet | R-290 Fleet | Direction |
|---|---|---|---|
| Equipment cost | Baseline | +3% to +5% | Slightly higher |
| Electricity consumption | Baseline | -5% to -8% | R-290 lower |
| Refrigerant cost (per kg) | Higher (~$8-12/kg) | Lower (~$2-3/kg) | R-290 ~75% cheaper |
| Maintenance & service | Baseline | -10% to -20% | R-290 lower |
| End-of-life refrigerant recovery | Specialized, costly | Simple, low-cost | R-290 lower |
| Payback period | N/A | 18-24 months (typical) | R-290 premium recovered |
| 5-year TCO | Baseline | -3% to -6% | R-290 lower |
Key insight: R-290 equipment costs 3-5% more up-front (mainly for safety components, A3-compatible compressors, and certification testing). The premium is paid back within 18-24 months through electricity and refrigerant savings. For larger fleets the absolute savings scale linearly—and the regulatory risk of holding R-134a equipment in 2026+ EU markets is eliminated.
Note on HFC quota exposure: Holding R-134a equipment in the EU after 2026 means paying F-Gas quota on every service event. Yichuhui has received multiple buyer inquiries specifically asking for R-290 to eliminate quota exposure.
Variable-Speed Compressor Integration
Modern inverter compressors from leading manufacturers (e.g., Secop, Embraco/Embraco Nidec) are designed from the ground up for R-290. They modulate capacity from roughly 25% to 100% in response to actual cooling demand, eliminating the on/off cycling losses of fixed-speed compressors. Combined with R-290’s thermodynamic advantage, variable-speed systems deliver 25-35% annual electricity savings versus R-134a fixed-speed baselines. This combination is especially valuable in tight-footprint formats; see our convenience store refrigeration lineup for typical compact-deck configurations.
For B2B buyers, the practical recommendation is: specify R-290 + variable-speed compressor + electronic expansion valve (EEV) for new projects where total cost of ownership is the priority. The upfront premium is 8-12% higher, but the 5-year TCO is materially lower.
R-290 Product Applications
R-290’s 500 g charge limit per circuit (per EN IEC 60335-2-89:2022) defines its application envelope. The technology is now mature across most self-contained commercial refrigeration categories that fall within this charge limit. Below is the application envelope relevant to Yichuhui’s product line.
Beverage Merchandisers (Display Refrigerators)
Beverage merchandisers—single-door, multi-door, and open multi-deck—are the largest R-290 application segment by unit volume within Yichuhui’s product range. Typical charge sizes range from below 150 g to under 500 g, well within the EN IEC limit. The combination of energy efficiency (5-8% better than R-134a), quiet operation, and regulatory compliance makes R-290 the default choice for new installations. For a full overview of supermarket-grade configurations, see our supermarket refrigeration solutions.
Yichuhui’s R-290 beverage merchandisers include:
- Single-door upright glass display fridges (e.g., ABD series, AR series).
- 2-door / 3-door upright glass display fridges (DSRG series).
- Open multi-deck display merchandisers (MD, MCD, MRT series) for supermarket and convenience-store use.
- Air-cooled display fridges in mirrored and titanium-finish configurations (ARLM, ARLG series).
Typical R-290 charges per category are well below the 500 g per-circuit limit set by EN IEC 60335-2-89:2022.
Display Freezers and Ice Cream Display Freezers
Self-contained display freezers—top-mount, bottom-mount, glass-door, and ice cream chest/curved-glass variants—are an ideal R-290 application. Yichuhui’s display freezer range covers:
- Top-mount and bottom-mount display freezers (AFBB, AFTB series).
- Pearl-white and sleek-black display freezer formats.
- Single- and dual-curved-glass ice cream display freezers (ICDF-1, ICDF-2).
- Single- and double-door commercial chest freezers (CCF-1, CCF-2) — for low-temperature storage and island placement.
R-290’s thermodynamic efficiency advantage is particularly pronounced in low-temperature applications, where evaporator temperatures of -20 °C to -25 °C are required.
Multi-Deck Open Display Merchandisers
Open-front multi-deck display merchandisers (MD, MCD, MRT, MLD, MCT, MCLT series) for supermarkets and convenience stores can be designed as self-contained units with R-290 charges under 500 g, particularly for shorter case lengths. For longer cases (2.5 m+), a split system with a remote condensing unit may be required to stay within the per-circuit limit—Yichuhui’s engineering team can advise on case length and refrigerant distribution for each project.
Commercial Chillers and Prep Tables
Glass-door refrigerated prep tables, sandwich/salad prep tables, and upright commercial refrigerators (DSGRT series, DSRG, ALF, ASF series) are well-suited to R-290 refrigerant. Typical charges sit comfortably below the 500 g limit and deliver the energy and regulatory benefits of R-290 in a self-contained format.
Commercial Freezers (Reach-in and Chest)
Low-temperature commercial freezers (-18 °C to -25 °C) sit within R-290’s capability, but charge sizes tend to be near or at the 500 g limit. For chest freezers and small upright freezers, R-290 is the standard in the EU. For larger upright multi-door freezers, R-290 is now viable with optimized evaporator design and inverter compressors.
What About Walk-in Cold Rooms?
Walk-in cold rooms typically use remote refrigeration systems with charge sizes well above 500 g, which puts them outside EN IEC 60335-2-89:2022’s scope for self-contained R-290 units. Such systems typically rely on R-448A, R-449A, or CO₂ (R-744). Yichuhui’s product line focuses on self-contained commercial refrigeration for retail and foodservice applications; for cold-room projects, we recommend working with cold-room specialist contractors who can size refrigerant systems to the larger charge envelope.
Product Application Matrix (Yichuhui Range)

R-290 OEM/ODM Considerations for Commercial Refrigeration
R-290 OEM/ODM production requires specific equipment, training, and quality control. B2B buyers should evaluate these capabilities when selecting a manufacturing partner.
Dedicated Charging Station
R-290 charging must occur in a dedicated, ventilated hydrocarbon charging room with the following minimum features:
- Mechanical ventilation providing at least 6 air changes per hour.
- Continuous hydrocarbon leak detection (calibrated to propane/methane).
- Intrinsically safe electrical fittings (ATEX/IECEx certified for Zone 1 or Zone 2).
- Nitrogen-purged charging equipment to prevent moisture ingress.
- Vacuum pump with hydrocarbon-compatible oil.
- Recovery system for any unused refrigerant.
- Emergency ventilation override and gas isolation valves.
Quality Control Procedures
R-290 quality control extends the standard refrigerator QC process with these R-290-specific checks:
- Leak test on every unit: 100% helium mass spectrometer or pressure-decay leak test on the sealed refrigerant circuit.
- Vacuum test: Each unit pulled to a deep vacuum and held; rise rate checked against spec.
- Charge verification: Every charge weighed on a calibrated scale; data logged against serial number.
- Electrical safety: Hi-pot, ground continuity, and insulation resistance tests per EN 60335-1.
- Functional test: Run unit through its full operating envelope; verify pull-down time, steady-state temperatures, and power consumption.
- A3 label application: Yellow triangular A3 label affixed to cabinet, plus refrigerant charge, oil type, and serial number on the data plate.
- Documentation pack: CE Declaration of Conformity, test report, refrigerant data sheet, operator manual.
Yichuhui’s QC process: Every R-290 unit passes through a multi-station QC gauntlet covering incoming component inspection, cabinet assembly QC, brazing leak check, vacuum and charge, electrical safety, functional run, and final cosmetic. Failure modes are tagged, root-caused, and fed back to the production line.
Documentation and Labeling
R-290 equipment must carry specific labels and documentation per EN 378 and EN IEC 60335-2-89:
- Yellow A3 warning label (triangle with flame symbol) on the cabinet exterior.
- Refrigerant data plate listing R-290 designation, charge weight in grams, GWP, and oil type.
- Manufacturer data plate with model, serial, electrical specs, and CE marking.
- Operator manual with safety instructions, leak response procedures, and service contact information.
- Service manual (separate document) with refrigerant recovery procedures, leak test points, and spare parts list.
Worker Training
A2 and A3 refrigerant production requires workers to complete hydrocarbon handling training covering:
- Flammable refrigerant properties and hazards.
- Charging and recovery procedures.
- Leak detection and emergency response.
- Personal protective equipment use.
- Static electricity control (propane is highly susceptible to static discharge ignition).
Yichuhui’s R-290 production line operators complete initial hydrocarbon-handling training and annual refreshers. Training records are kept per ISO 9001:2015 documentation requirements.

R-290 Application Cases (anonymized)
Case 1: Eastern European supermarket chain (anonymized). A multi-store supermarket chain in Eastern Europe transitioned a portion of its refrigerated merchandising fleet from R-134a display cases to Yichuhui’s R-290 units. The project involved close coordination between the retailer’s QA team and Yichuhui’s engineering team on per-unit leak testing, technical file completeness, and EN IEC 60335-2-89:2022 conformance. Independent field measurement after rollout confirmed materially lower per-unit electricity consumption versus the previous R-134a fleet. For a complementary Southeast Asian deployment of R-290 multi-deck cases under tropical ambient conditions, see our SE Asia supermarket case study.
Case 2: GCC beverage merchandiser rollout. Yichuhui’s GCC G-Mark certified R-290 beverage merchandisers have been deployed across supermarket and convenience-store rollouts in the Gulf region since 2021. Buyer feedback repeatedly cites R-290 status (no F-Gas quota exposure) and energy efficiency as the primary specification drivers in the region.

Frequently Asked Questions
Below are the questions B2B buyers most often ask before specifying R-290. For a broader Q&A library covering refrigerants, charging, certifications, and service, see our R-290 FAQ hub.
Is R-290 safe for commercial kitchens and food service environments?
Yes, when the equipment is designed, installed, and serviced to EN IEC 60335-2-89:2022 standards. The 500 g charge limit per circuit is calibrated to keep the maximum possible refrigerant concentration in a typical installation below 25% of the Lower Flammability Limit (LFL). Yichuhui’s R-290 commercial foodservice equipment (refrigerators, prep tables, display freezers, beverage merchandisers) is designed to meet these standards and is supported by trained-hydrocarbon service procedures. The key requirements are: self-contained design (no field-installed line sets), spark-proof electrical components, and service by hydrocarbon-certified technicians. For typical layouts and ventilation specifications in full kitchens, our restaurant kitchen refrigeration reference covers prep tables, reach-ins, and ice machines side by side.
How much R-290 is in a typical commercial refrigeration unit?
The 500 g per-circuit limit applies to all self-contained R-290 commercial refrigeration equipment under EN IEC 60335-2-89:2022. Yichuhui’s standard product range (single-door to multi-door beverage merchandisers, display freezers, prep tables, multi-deck open merchandisers, and ice cream display freezers) is engineered to stay comfortably below this limit on a per-circuit basis. Specific charge sizes per product are listed on the data plate of every unit and in the model’s technical file. Contact Yichuhui with your product requirement for a model-specific charge specification.
Can I retrofit my existing R-134a equipment to R-290?
Short answer: don’t, unless you have a very specific reason. Here is the math.
R-134a and R-290 are different refrigerants. Different thermodynamic profiles, different lubricant requirements (POE oil for R-134a does not dissolve in R-290), and different safety classifications (A1 versus A3). Field-converting an R-134a unit to propane voids the CE marking, breaks EN 378 leak-test compliance, and leaves you with a piece of equipment no service tech can legally recover refrigerant from. If you absolutely must transition before end-of-life, the practical options are R-513A as an R-134a drop-in (GWP still high at 573, but legal) or full equipment replacement.
Now, the failure modes I have actually seen in the field, in order of how badly they ended:
Worst case: the compressor burns out within months because the old POE oil from the R-134a era does not dissolve in R-290, the bearing seizes, and you are paying for a new compressor plus a full leak check. Repair cost: a few hundred dollars plus several hours of technician time. Annoying, but survivable.
Worst-er case: the propane charge leaks in a tight retail back room, hits a gas detector, triggers an emergency service call, and the store has to be evacuated until the fire department verifies the all-clear. Downtime cost adds up fast, plus the regulatory paperwork in some EU jurisdictions.
Worst-er-est case: a service tech opens the system two years later, does not know what is in it, and tops it off with R-134a. Now you have a 50/50 blend of propane and HFC that is not R-290, not R-134a, not legally recoverable under EU F-Gas, and will damage the next compressor.
The honest recommendation: retrofit is not a cost-saving measure, it is a risk transfer. Replace at end-of-life. If you cannot wait, use a legal drop-in like R-513A. If you want R-290 specifically, buy R-290.
What is the cost premium for R-290 equipment vs R-134a?
For self-contained commercial refrigeration, the R-290 cost premium is typically 3-5% over R-134a equivalent models. The premium covers A3-compatible compressors, spark-proof electrical components, dedicated charging infrastructure, and certification costs. This premium is recovered within 18-24 months through lower electricity and refrigerant costs. For new EU market equipment purchased in 2026 or later, R-134a is no longer legal, so R-290 is effectively the default. Yichuhui’s R-290 OEM/ODM pricing is available on request with project-specific quotations.
Conclusion & Next Steps
R-290 propane refrigerant has moved from niche alternative to default choice for self-contained commercial refrigeration in 2026. Three forces are converging: the EU F-Gas Regulation 2024/573 ban on R-134a from January 1, 2026; the 500 g charge limit expansion under EN IEC 60335-2-89:2022; and 20+ years of OEM manufacturing experience that has eliminated the early-stage safety and reliability concerns.
For B2B buyers, the path forward is clear:
- Specify R-290 for all new self-contained commercial refrigeration in the EU, GCC, CIS, and most regulated markets.
- Plan for the 2026 EU deadline if you currently hold R-134a inventory—stock rotation, service contracts, and end-of-life replacement all need to be aligned with the regulation.
- Evaluate 5-year TCO, not upfront price. R-290’s 3-5% equipment premium is offset by 5-8% electricity savings and roughly 75% lower refrigerant cost. The 5-year TCO favors R-290 in nearly every application.
- Choose an OEM with verified R-290 production capability. Dedicated charging infrastructure, certified technicians, and CE / EAC / GCC certification on the actual product range—not just the company—should be non-negotiable.
- For complex applications (multi-deck display cases, large open merchandisers), engage with the OEM’s engineering team early. R-290 design requires different evaporator and compressor sizing than R-134a, and a competent engineering team will optimize the system for your specific climate and usage profile.
