Freon MO49Plus (R-437A) is an HFC retrofit refrigerant for R-12 in automotive air conditioning and stationary refrigeration systems and for replacing HCFC-containing refrigerant blends (e.g., MP39, MP66, and R-409A) in stationary refrigeration systems. Freon MO49Plus is compatible with traditional and new lubricants; in most cases no change of lubricant during retrofit is required.Freon™ MO49Plus (R-437A) is a versatile HFC refrigerant designed as a replacement for R-12 in refrigeration and air-conditioning systems. It offers excellent cooling performance with minimal system modifications, making it ideal for retrofitting existing equipment. Compatible with both mineral and alkylbenzene oils in many applications, R-437A provides reliable operation, improved efficiency, and reduced maintenance requirements. It is widely used in commercial refrigeration, transport refrigeration, and air-conditioning systems where dependable R-12 replacement performance is required.
