Environmental Responsibility and A2L Refrigerants
The global objective to minimize greenhouse gas emissions has highlighted the need for lower GWP refrigerants. Progressively, the HVAC industry has introduced A2L refrigerants, which, despite having a higher flammability than traditional A1 refrigerants, are notably less combustible than A3 hydrocarbon types.
Compliance and Standards
A standard known as UL 60335-2-40 has been created to ensure keeping with safety measures
A standard known as UL 60335-2-40 has been created to ensure compliance with safety measures in North American markets, pinpointing components used in ignition-proof systems.
This standard is a more conservative adaptation of the international IEC 60335-2-40, widely used in Europe, ensuring the safe use of low-GWP refrigerants.
Conclusion
With its recent UL Certification and focus on utilizing A2L refrigerants, NOARK Electric continues to provide safe and reliable definite purpose contactors for a variety of applications.

Why A2L Refrigerant?
The goal to reduce global warming will require a global approach, and many calls to action are being implemented or are already in effect around the world. For example, in support of the Kigali Amendment to the Montreal Protocol and the Paris Climate Agreement, an area of focus is on the reduction of potent greenhouse gas emissions, such as the hydrofluorocarbon (HFC) refrigerants, in the atmosphere. This mandate is prevalent around the globe, where measures are curtailing the use of these products.
The air conditioning and refrigeration industry has been actively working since 2006 to develop a new classification of refrigerants, known as A2L, to meet the lower Global Warming Potential (GWP) challenge. While having slightly higher flammability characteristics as compared to traditional A1 refrigerants, A2Ls are much harder to ignite and are much less flammable than A3 hydrocarbon refrigerants.
A new standard was created for certain components, for example, arcing/sparking electrical components used in A2L flammable refrigerant systems. These components can have a higher risk of igniting the refrigerant. According to UL 60335-2-40, it provides the testing to certify that these components comply with the Flame Arrest-Protected component standard in ignition and explosion-proof systems.
The Current Updates According to UL Solutions:
UL 60335-2-40 3rd Edition is an ANSI/SCC-approved standard covering electrical heat pumps, air-conditioners, and dehumidifiers. Further, it is a binational standard (U.S. and Canada) that is based on the international IEC 60335-2-40 standard.
IEC 60335-2-40 is currently being used as the basis for the design, evaluation, testing, and certification of HVAC equipment using low-GWP refrigerants in places like Europe. Overall, UL 60335-2-40 has adopted more conservative safety requirements than the IEC standard to address the unique product usage of the North American market.
