Refrigerants are chemicals used in cooling systems like air conditioners, refrigerators and freezers. Most mechanical devices depend on the chemical reactions from these liquids to remove heat from an enclosed system. Need to identify the kind of refrigerant in a cooling system? We have a selection of identifiers and diagnostic refrigerant analyzers that can differentiate between various types of refrigerants and their component contents. With R-22 refrigerant being rapidly phased out by 2020, don’t wait to convert to alternatives. Our full assortment of cost-effective alternatives includes R-427A (4LFC4) and NU-22B (6PPV1), both of which do not contain ozone-depleting hydrofluorocarbons (HFC) and are easy retrofits for most commonly used systems. Find the refrigerant and refrigerant alternatives your system needs today.
