What is R 409A refrigerant?

As various global regulations drive the gradual phaseout of certain refrigerants, the Freon™ brand continues to develop alternative refrigerant options, including Freon™ 409A (R-409A) refrigerant. Freon™ 409A carries an ASHRAE A1 safety classification and blends R-22, R-142b, and R-124.

What type of oil should I use when replacing R-12 with Freon™ 409A?

Original equipment manufacturers (OEMs) recommend using either mineral oil (MO) or alkylbenzene (AB) oil when replacing R-12 with Freon™ 409A. Many applications don’t require oil replacement; consult your OEM to find out when AB oil must be used. Freon™ 409A is a nonflammable hydrochlorofluorocarbon (HCFC) based refrigerant.

What is a retrofit blend for R-12 refrigeration?

Looking for something else? A retrofit blend for R-12 refrigeration systems. The pressure and system capacity match R-12 when the blend is running in a 10°F to 20°F evaporator, and there is typically 13°F temperature glide in the evaporator.

What is the difference between R-12 and R-409A?

Discharge pressure and temperature increases compared to R-12, which may be a problem in very hot ambient conditions. Capacity holds well into lower application temperatures (-30°F). R-409A mixes well with mineral oil down to 0°F.

What is the normal low pressure for R 134a refrigerant?

The pressure gauges for this refrigerant stays between 22 PSI and 57 PSI (pounds per square inch). But you have to keep in mind that there are two different sides to this chart. And you have to consider the low as well as the high side. Hence, the normal low-pressure side for R 134a needs to be less than 90 degrees.

What is the ideal refrigerant pressure for a refrigerator?

The pressure gauges for this refrigerant stays between 22 PSI and 57 PSI (pounds per square inch). But you have to keep in mind that there are two different sides to this chart. And you have to consider the low as well as the high side.
