| Environmental Properties [top] |
|
Environmental organizations and Green
Peace have endorsed hydrocarbon refrigerants because they are ecologically safe
and non toxic. RED TEKŪ refrigerants are non ODP products and are very low
global warming.

RED TEKŪ refrigerants are fully
compatible with most common refrigeration lubricants. All RED TEKŪ refrigerants
are soluble with all refrigeration oils. RED TEKŪ refrigerants should not be
used with silicone oils.

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

| Seal/Refrigerant Compatibility [top] |
|
Most all common elastomer and plastic
refrigeration materials used as o-rings, seals, and gaskets are compatible with
RED TEKŪ refrigerants. Butyl hoses are incompatible and should not be used
with hydrocarbon refrigerants.
