R422D refrigerant (MO29) is a simple to use, zero ODP (ozone depletion potential)HFC refrigerant, withR22Very close cooling capacity and efficiency, with a lower exhaust temperature than R22, and at low temperatures, it provides up to 8% cooling capacity and up to 14% efficiency than R22; at medium temperature conditions and a subcooling of 10°F(6°C), the cooling capacity of MO29 is about 5% lower than R22, but the efficiency is equivalent to R22.
R422D can directly replace R22's direct expansion (DX) refrigeration equipment in medium and low temperatures, including commercial supermarket systems, fixed direct expansion (DX) air conditioning equipment, medium and low temperature commercial and industrial direct expansion (DX) refrigeration systems, such as: catering refrigeration, supermarket display cabinets, food storage and processing, ice machines, household and commercial air conditioners (AC), direct expansion (DX) water coolers, etc.
R422D provides simple, efficient and economical direct replacements, and has simpler replacements than R404A, R507, and R407C. R422D refrigerant is compatible with traditional and new lubricating oils. In most cases, there is no need to replace the refrigerant oil during the replacement process; there is no need to replace the temperature adjustment expansion valve, and the degree of superheat can be adjusted as needed. After filling and use, if it is found that there is arefrigerantIf the capacity is insufficient, it can be replenished directly without draining all the charged refrigerant.

Regulatory and compliance status (R422D / R422D (R125/R134a/R600a blend))
R422D (R422D (R125/R134a/R600a blend)) has an ODP of 0 and is not an ozone-depleting substance, and therefore is not bound by the Montreal Protocol phase-out schedule; but as a fluorinated greenhouse gas (F-gas, GWP 2690), it is controlled under the Kigali Amendment and the HFC reduction policies of major economies. The following are the regional status as of 2026, for reference in procurement and compliance decisions.
EU
- RegulationF-gas Regulation (EU) 2024/573, in force since 2024-03-11
- HFC quota60% in 2025–28, 30% in 2029–33, 20% in 2034–35, 15% from 2036; HFC fully phased out by 2050
- New equipment restrictionsNew refrigeration/air-conditioning equipment with GWP>150 has been banned for sale in phases since 2022 (commercial refrigeration 2022, standalone equipment 2025, fully by 2030)
- For R422DGWP 2690 > 150 — not permitted for new equipment of this type in the EU; servicing or top-up of existing equipment is unaffected
US
- RegulationAmerican Innovation and Manufacturing (AIM) Act (in force since 2020-12-27)
- TargetHFC production and consumption reduced by 85% by 2036
- Quota cap60% in 2024–28, 30% in 2029–33, 20% in 2034–35, 15% from 2036
- For R422DRegulated HFC, exchange value accounted by GWP 2690
China
- RegulationKigali Amendment (entered into force for China on 2021-09-15)
- Baseline2024 production/consumption freeze (production 18.53 billion tCO₂e, consumption 9.05 billion tCO₂e)
- Reduction10% reduction by 2029, 30% by 2035, 50% by 2040, 80% by 2045
- For R422DProduction and use are subject to quota management
- Domestic procurement qualificationHFC-class refrigerants require environmental filing; see the Q&A below (system: new-ods.ozone.org.cn)
Japan
- RegulationAct on Rational Use and Proper Management of Fluorocarbons
- MechanismSets caps based on “weighted-average GWP” for designated products + compliance deadlines (not an all-sector ban)
- Typical capsDomestic air conditioning ≤750 (2018), commercial air conditioning ≤750 (2020), automotive air conditioning ≤150 (2023), condensing/freezing units ≤1500 (2025), cold storage ≤100 (2019)
- For R422DGWP 2690 exceeds condensing/refrigeration units (≤1500), residential air conditioners (≤750), commercial air conditioners (≤750), vehicle air conditioners (≤150), cold stores (≤100) — such new equipment must switch to a lower-GWP refrigerant
Other countries and regions (grouped by the Kigali Amendment)
Apart from the four columns of EU / US / China / Japan, the global 170+ Kigali parties all comply under the A5 (developing countries) / non-A5 (developed countries) groupings of the Montreal Protocol, and none impose equipment-level bans. The grouping determines the HFC reduction pace and is unrelated to geography — for example, the Middle East Gulf and India belong to A5 Group 2, while Brazil, Mexico and Chile belong to A5 Group 1 (same group as China). The table below is a quick reference for the groupings of major markets:
| Grouping | HFC reduction pace | Major countries / regions (representative) |
|---|---|---|
| A5 Group 1 (developing countries, including China) | 2024 freeze → 10% reduction by 2029 → 30% by 2035 → 50% by 2040 → 80% by 2045 | Brazil, Argentina, Chile, Colombia, Peru, Mexico, South Africa, South Korea, Thailand, Indonesia, Malaysia, Vietnam, Egypt, Nigeria, etc. (about 140 countries in total) |
| A5 Group 2 (high-ambient-temperature group, HAT) | 2028 freeze → 10% reduction by 2032 → 20% by 2037 → 30% by 2042 → 85% by 2047 | India, Bahrain, Iran, Iraq, Kuwait, Oman, Pakistan, Qatar, Saudi Arabia, United Arab Emirates |
| Other non-A5 (developed countries, except EU/US/Japan) | 85% reduction by 2036 / reduced to 15% by 2050 | Canada, Australia, New Zealand, Switzerland, Norway, United Kingdom, Russia* (first two steps delayed: 5% by 2020, 35% by 2025), etc. |
For R422D: subject to quota constraints, long-term supply restricted and prices trending upward. For the complete list of Parties and groupings, refer to the UNEP Ozone Secretariat (data version 2026.09).
Buyer conclusion: R422D is still legally produced, sold and used worldwide and is not subject to a comprehensive ban; but as a fluorinated greenhouse gas (GWP 2690), its supply is constrained by national quotas and prices trend upward in the long term. In the EU, new equipment with GWP>150 has been banned in stages; GWP 2690 exceeds that threshold, so it is not permitted for such new equipment; The US and China are also progressively reducing HFCs according to their own schedules; Japan promotes substitution for domestic/commercial/automotive air conditioning based on GWP caps. Recommendation: for new projects, prioritise evaluating low-GWP alternatives (R32, R454B, R513A or a hydrocarbon refrigerant); existing equipment can continue to be maintained with R422D. Domestic customers must complete environmental filing (“Ozone-Depleting Substances Information Management System”) before purchasing, and suppliers must verify the filing and may not sell to individuals or enterprises not filed as required.

R422D refrigerant 10kg is a refrigerant/chemical product. It is widely used in refrigeration equipment such as refrigerators, freezers, water dispensers, automotive air conditioners, central air conditioning, dehumidifiers, cold storage and commercial refrigeration, as well as in aerosol propellants, blowing agents, fire-extinguishing and cleaning applications. See the product page for details.
R422D refrigerant 10kg is used as a common working fluid in refrigeration, air-conditioning and industrial applications. When replacing or retrofitting a system, qualified personnel should perform the work, paying attention to system compatibility and lubricant matching, and following relevant safety standards.
Store in a cool, dry, well-ventilated warehouse away from fire, heat sources and direct sunlight. Cylinders should be placed upright and protected from falling. Transport according to regulations for high-pressure gases or hazardous chemicals, with careful handling to avoid damage to cylinders and valves.
Ensure adequate ventilation at the workplace. Avoid direct skin contact with liquid refrigerant (risk of frostbite). Keep away from open flames and high heat. Use dedicated tools and protective equipment. In case of leakage, evacuate, ventilate and contact professionals.
The exact Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) are listed in the Physical Properties table on the product page. Select refrigerants considering energy efficiency, safety and environmental impact.
Multiple package sizes are available (e.g., cylinders, drum or ton packages - see product page). Bulk orders are supported. Contact sales for the latest quote and lead time.
