Properties [top] |
|
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.

RED TEK® 12a, 22a, and 502a hydrocarbon refrigerants are 99.7% pure saturated
hydrocarbon. Total quality is assured from product development through actual
production. RED TEK® refrigerants blending process complimented by ISO 9002
certification, means consistent, continuing conformance.

Compatibility [top] |
|
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.
