The emerging role of A2L refrigerants in commercial refrigeration applications is a topic of spirited conversation among industry stakeholders. As the transition from high-global warming potential (GWP) hydrofluorocarbon (HFC) refrigerants to lower-GWP alternatives continues, A2L refrigerants are among the many likely options under consideration.
Classified as “mildly flammable,” A2Ls are currently approved for use and deployed in commercial refrigeration applications in Europe and other global regions — where they have proven to be both operationally safe and environmentally friendly. These installations have piqued the interest of food retailers in the U.S., who seek to comply with regulatory mandates and/or meet sustainability initiatives.
