If required, systems can later be converted relatively easily to non-flammable (A1) HFO/HFC alternatives with a GWP of approx. 600 (Low GWP" alternatives for HFC … 2021-01-20 HFC alternatives can be identified via the portal for each product in categories such as Appliances, HVAC/Mechanical, Cleaning Products, Refrigeration Systems, and Vehicles and Vehicle Products. When SNAP is identified as the environmental program relevant for federal procurement of a specific product, a link directs users to the applicable page within the SNAP program website that lists Hydrofluorocarbon (HFC), any of several organic compounds composed of hydrogen, fluorine, and carbon. HFCs became widely used as refrigerants in the late 1980s, but their status as potent greenhouse gases led to their manufacture and use becoming increasingly regulated in the 21st century.
