RS-45 is a blend of HFC and HC refrigerants, almost azeotropic, with zero Ozone Depleting Potential, used as a direct replacement (drop-in) for R-22 in systems equipped with adjustable expansion valve (TXW) and working in positive temperatures, medium and low up to -35ºC.
It is the recommended solution to substitute R-22 in flooded systems and big air conditioning units.
Easy, direct and efficient, RS-45 is compatible with the existing mineral oil in the installation. It provides the same cooling capacity as R-22, even in low temperatures and it is the perfect alternative for flooded evaporators thanks to its low glide temperature. It may be necessary to open/regulate the expansion valve.
