502a – Hydrocarbon-Based Refrigerant

RED TEK® 502a, a hydrocarbon-based refrigerant from Thermofluid Technologies, is a blend of environmentally safe hydrocarbon fluids designed as a direct replacement and retrofit refrigerant option for replacing R502 refrigerants in commercial air conditioning and refrigeration systems.


RED TEK 502a possess similar volumetric refrigerating effects to R502 refrigerants. Operates at lower head pressures and offers improved cooling properties and performance versus R22 and R502.

Lower Cost

502a refrigerant is far less expensive than R502 refrigerant. Furthermore, your air conditioning systems can experience increased energy savings of up to 30%.


RED TEK 502a refrigerants are organic, non-ozone depleting, non-toxic compounds. These refrigerants are endorsed by the Green Peace organization and are in full compliance with the UN Montreal Protocol.


502a operates at lower head pressures and offers improved cooling properties and performance versus R502. RED TEK Refrigerants are up to 40% more efficient than Hydrofluorocarbon refrigerants.


Compatible with most common refrigeration materials and lubricants including R22, R502, metal components, mineral and synthetic (Ester and PAG) lubricants, seals, gaskets, hoses, compressors, and O-rings. Red Tek 502a refrigerants are non-corrosive, non-caustic, and do not form acids in combination with system moisture.
