Honeywell Refrigerant Approved for Use in Supermarkets Ahead of EPA Regulations

Honeywell logoHoneywell’s Solstice N40 (R-448A) refrigerant has been approved for use by the EPA in applications ranging from stand-alone refrigeration systems to commercial refrigeration.

The EPA has also broadened approvals for the company’s Solstice N13 (R-450A) refrigerant, allowing it to be used in new vending machine applications.

The EPA approved the new low-global warming refrigerant uses under its Significant New Alternatives Policy (SNAP), which evaluates substitute chemicals and technologies that are safe for the ozone layer. The final rule will be published in the Federal Register in the coming weeks.

Global regulators are increasingly moving to phase out high-global warming refrigerants and, on July 2, the EPA announced regulations that will phase out the use of many of the world’s most potent HFCs, such as R-404A, in a variety of applications. The new regulation, effective summer 2016, will require supermarkets, the largest consumers of R-404A in the US, to discontinue use of R-404A as a retrofit refrigerant. R-404A will also not be permitted for use in new supermarkets beginning Jan. 1, 2017.

The EPA had previously given SNAP approval for Honeywell’s Solstice yf, also known as R-1234yf, a low-global-warming replacement for R-134a, which is commonly used for automotive air conditioning. It has also approved Solstice zd (R-1234zd) and Solstice ze (R-1234ze), which can be used in chillers and a wide range of other end uses.

The latest approvals allow Solstice N40 refrigerant to replace R-22 and R-404A in commercial refrigeration applications, including new and retrofit supermarkets, various types of commercial refrigeration equipment, ice machines and refrigerated transportation.
