Hydrocarbon refrigerants are environmentally friendly, non-toxic, non-ozone-depleting replacement for chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs). From a chemical point of view, a hydrocarbon is the simplest organic compound, consisting entirely of hydrogen and carbon.
R134a is an inert gas used primarily as a refrigerant for domestic refrigeration and automobile air conditioners. It first appeared in the early 1990s as a replacement for CFC-12 (also known by its trade name Freon), which has ozone depleting properties.
Freon™ 404A refrigerant Freon™ 404A (HP62) has been the long-standing HFC replacement for R-502 and R-22 in refrigeration applications. HFC-404A is included in the U.S. EPA SNAP de-listing of HFCs that will no longer be acceptable in certain end use applications in the U.S. market.
Freon™ 407C (R-407C) is a R-22 replacement primarily for air-conditioning. It's a HFC blend that requires a POE lubricant. R-407C is included in the U.S. EPA SNAP de-listing of HFCs that will no longer be acceptable in new equipment in certain end use applications in the U.S. market.
R-410A, sold under the trademarked names Suva 410A, Forane 410A, Puron, EcoFluor R410, Genetron R410A, and AZ-20, is a zeotropic, but near-azeotropic mixture of difluoromethane (CH 2 F 2, called R-32) and pentafluoroethane (CHF 2 CF 3, called R-125), which is used as a refrigerant in air conditioning applications.
