The refrigerant recovery and reclamation sector is striving to keep up with the changes taking place in the world of refrigerants, which means it is constantly creating new products to seamlessly adapt to the latest batch of regulations and refrigerant phaseouts.

What long-term implications will this have on the refrigerant-recovery industry, which has been built on recovering chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs) — refrigerants that are increasingly being phased out?
