Freon™ MP39 is an HCFC retrofit refrigerant for R-12 in stationary positive displacement air-conditioning and refrigeration systems such as walk-in coolers, beverage dispensers, vending machines, and supermarket systems. Field experience has shown that no oil change is needed in many unitary and close-coupled systems.
R-401A; A1 Safety Classification
Medium- and low-temperature positive displacement equipment in supermarket systems and walk-in coolers.
- Works with existing mineral oil (MO) in many unitary and close-coupled systems.
- Alkylbenzene (AB) oil is recommended for optimum oil return.
- One compressor oil change to AB will typically remove 50% to 80% of the existing MO, which satisfies the recommendations and requirements of most compressor manufacturers; 10% to 25% less refrigerant is needed. See retrofit guidelines for full details.
