Our Mission

Through the advancement of research and development in the field of HVAC, (Heating Ventilation Air Condition) systems, Tung Fung is proud to introduce R134a, otherwise known as Tetra fluoro ethane.

R134a, is used as substitute refrigerant, for R12 & R22 which are ozone depleting. R134a is rated as zero O.D.P.

Among many refrigerants, R134a is a beneficial alternative. It is a non-ozone depleting refrigerant, non-flammable and non-toxic.
