Application for RED TEK® Refrigerants

RED TEK® hydrocarbon refrigerants are used in a wide range of automotive, commercial, and industrial air conditioning and refrigeration systems.

REFRIGERANT COMPOSITION REPLACEMENT
RED TEK® 12a zeotrope (CFC-12, HFC-134a)
RED TEK® 22a pure HCFC-22
RED TEK® 502a zeotrope R502, HFC-407C


Environmental Properties

Environmental organizations and Green Peace have endorsed hydrocarbon refrigerants because they are ecologically safe and non toxic. RED TEK® refrigerants are non ODP products and are very low global warming.

Seal/Refrigerant Compatibility

Most all common elastomer and plastic refrigeration materials used as o-rings, seals, and gaskets are compatible with RED TEK® refrigerants. Butyl hoses are incompatible and should not be used with hydrocarbon refrigerants.
