R134a Refrigerant Gas

Danus R134a refrigerant (chemical name as 1,1,1,2-Tetrafluoroethane) is a hydrofluorocarbon (HFC) gas, with a not relevant ODP potential.


R134A Refrigerant OVERVIEW

Danus R134a refrigerant (chemical name as 1,1,1,2 – Tetrafluoroethane) is a hydrofluorocarbon (HFC) gas, with a not relevant ODP potential. It can be used both pure as well as with blends. It is considered as one of the principle replacement products for CFC and HCFC refrigerants. It can be used at medium and high temperatures. For its energy efficiency and refrigerating capacity, the refrigerant danus R134a has similar performance to the R12 and is considered as a possible alternative to the refrigerant R12 in a wide range of applications. It and is widely used in the new installation of refrigeration and air conditioning and many automotive A/C systems.
