What is the best replacement for R-404A?
What are the best replacements for R404A? For cold rooms and other small to medium commercial refrigeration applications, R448A and R449A and R452A or R134a are excellent alternatives to R404A, with from 50 to 65% reduction in GWP.
What type of lubricant must be used for a R-404A system?
Mineral Oil
Mineral Oil: Mineral oil has been the lubricant of choice for systems utilizing many of the CFC and HCFC refrigerants. Both the CFCs and HCFCs tend to have adequate miscibility with mineral oil, helping to ensure acceptable oil return under normal operating conditions.
Is R404A a blend?
A Widely Used and Thoroughly Trusted Refrigerant Freon™ 404A (R-404A) is a blended hydrofluorocarbon (HFC) refrigerant comprised of R-125, R-134a, and R-143a. It was designed to replace R-502 and R-22 used in commercial refrigerator equipment for low and medium temperature ranges.
Is R404A ozone friendly?
The refrigerant R404a is an alternate refrigerant to CFCs and HCFCs as they are ozone friendly and have less Global Warming Potential (GWP) than R12 and R134a.
What is Forane R-22?
Forane® 22 refrigerant (R-22) is used in a broad range of applications, including residential and commercial air conditioning, refrigeration, chillers, room air conditioning, heat pumps, transport refrigeration, and other comfort cooling and refrigeration applications.
Is Forane 22 the same as R-22?
