Low Global Warming Potential (GWP) Refrigerants from UL Solutions

Product Profile

A new Kigali amendment reduction milestone will come into force in January 2025. Therefore, air conditioning and commercial refrigeration manufacturers need to identify alternative refrigerants to meet these new requirements to reduce products’ greenhouse emissions.

As you approach the A2L/A3 transition, consider the advantages of navigating the changing landscape of low Global Warming Potential (GWP) compliance and trade to gain access to new markets and offer safer products around the globe — protecting people, products and reputations.

UL Solutions is a leader in the HVAC/R industry and a trusted third party in the testing, inspection and certification (TIC) business. They have the knowledge, expertise and capabilities to help you navigate the transition.

Rely on their experts to understand the mitigation requirements for commercial refrigeration, as well as for air conditioners, heat pumps and dehumidifiers, including:

  • UL 60335-2-89, second edition, the Standard for Household and Similar Electrical Appliances - Safety - Part 2-89: Particular Requirements for Commercial Refrigerating Appliances and Ice-Makers with an Incorporated or Remote Refrigerant Unit or Motor-Compressor
  • IEC 40335-2-89, third edition
  • UL 60335-2-40, fourth edition, the Standard for Household and Similar Electrical Appliances - Safety - Part 2-40: Particular Requirements for Electrical Heat Pumps, Air-Conditioners and Dehumidifiers
  • IEC seventh edition
