The use of fluorinated greenhouse gases is regulated and current legsislation provides gradual transit to refrigerants, which are more environmentally friendly. First step is transit on refrigerants with less global warming potential.

Refrigerant R449A is new refrigerant with considerably lower global warming potential than most of existing traditional refrigerants and thermodynamic  properties max close to those of R404A refrigerant.

Refrigerant R449A can be used either for retrofit of existing systems as well as for new installations.

Major equipment and components manufacturers approved R449A use in their equipment:
