How to Recharge the Freon in a Commercial Refrigerator or Freezer
Chlorofluorocarbons (CFCs,) often known as Freon®, and their replacements, hydrochlorofluorocarbons (HCFCs), are being phased out, globally. Consequently, R-22, HCFC-141b, HCFC-142b can no longer be produced or imported into the United States. Freon that has been stockpiled or that is cleaned and recycled, however,...
R32 vs R290 vs R134a vs R12 Refrigerant
With more refrigeration and HVAC units being retrofitted to support new refrigerant bans and protocols, knowing about these key chemicals is crucial to maintenance and repairs. When technicians and facility managers search the web to learn about the refrigerant in the unit they're working on, there are four types that often...
U.S. Refrigerant Phase Out Chart & Info
In the United States, hydrochlorofluorocarbon (HCFC) refrigerants are being slowly phased out from production or being importing. The U.S. Environmental Protection Agency (EPA) still allows many of these types of HCFCs refrigerants to be used in repairs or retrofitting. However, without new production, the cost is becoming more...
