What is R408A used for?

R408A, an HCFC-based refrigerant, is a cost-effective retrofit refrigerant for R-12 refrigeration systems such as walk-in coolers, beverage dispensers, vending machines, domestic and supermarket systems.

What does R408A replace?

R408A, also known as Forane® FX10, is an HCFC blend designed to be a retrofit replacement for R502 in medium and low temperature refrigeration applications.

What oil does R408A use?

mineral oil
R-408A can be used with mineral oil, alkylbenzene, or POE lubricants. Systems operating with R-502 and mineral oil and showing adequate lubricant return to the compressor may continue to use mineral oil with R-408A.

Can you use 407A with mineral oil?

R-407A is immiscible with mineral oil and alkylbenzene and will require most of the original system oil to be replaced. Drain existing mineral oil or alkylbenzene from the compressor sump, suction line accumulators, etc. Record the amount of oil removed.

What is R502 refrigerant used for?

Developed for use in low temperature refrigeration (the evaporator pressure stays out of vacuum down to -40°F). R-502 offers lower discharge temperature and improved capacity compared to R-22.

What replaces R502 refrigerant?

R404A refrigerant is accepted as an alternative to R502 in the new equipment. It can be used also for charging of some systems operating on R502, such as commercial refrigeration equipment of big universal shops, refrigeration facilities of food industry factories, transport refrigeration facilities.

Is R502 being phased out?

An R-502 Replacement for Limited Condensing Capacity Systems Older systems with limited condensing capacity, and low- or medium-temperature commercial refrigeration systems used in supermarkets often use R-502, which is now being phased out as part of the Montreal Protocol.

Can R22 replace R502?

R507 is a HFC blend, used as a replacement for R502 and R22 in low and medium temperature refrigeration. With a Global Warming Potential (GWP) of 3985, R507 is under similar scrutiny to R404A.

What oil does 407A use?

Forane® 407A requires polyolester (POE) lubricant to ensure reliable oil return and circulation throughout the system. In many cases the original system oil can be reused. Due to the zeotropic nature of Forane® 407A, it should be charged as a liquid to prevent fractionation.

Is 407A being phased out?

Among the HFCs and HFC-blend refrigerants affected by the regulations are several that are familiar to facility managers: R-404A, R-134a, and R-410A and R-407C, used to replace R-22. Under the rules, new chillers would no longer be produced using these refrigerants after Jan. 1, 2024.

Is R502 refrigerant still used?

What is r-408a refrigerant?

Freon™ 408A (R-408A) Refrigerant An R-502 Replacement for Limited Condensing Capacity Systems Freon™ 408A (R-408A) refrigerant is a hydrochlorofluorocarbon (HCFC) option designed to replace the hydrofluorocarbon (HFC) refrigerant R-502.

Do I need an oil change when retrofitting from R-502 to 408A?

An oil change isn’t necessary when retrofitting systems from R-502 to Freon™ 408A. However, some original equipment manufacturers (OEMs) do recommend switching from MO to alkylbenzene (AB) oil to achieve optimum oil return. Consult your OEM for guidance.

What type of Freon is used in commercial refrigeration systems?

Older systems with limited condensing capacity, and low- or medium-temperature commercial refrigeration systems used in supermarkets often use R-502, which is now being phased out as part of the Montreal Protocol. Freon™ 408A (R-408A) is a very effective retrofit option for that equipment.
