Freon™ MO49Plus (R-437A) Refrigerant

A Versatile Replacement for Common R-12 Service Blends

Freon™ MO49Plus (R-437A) refrigerant was created as a hydrofluorocarbon (HFC) retrofit for service blends like R-101A, R-401B, and R-409A that contain hydrochlorofluorocarbon (HCFC) components.

Freon™ MO49Plus provides a quick, cost-effective way to retrofit existing R-12 and R-500 equipment currently using HCFC blends (Freon™ MP39, Freon™ MP66, and Freon™ R-409A). Those refrigeration applications, designed for R-12, include:

  • Food service/restaurant storage
  • Supermarket display cases
  • Food storage and processing
  • Domestic refrigerators/freezers

Features and Benefits

Freon™ MO49Plus is compatible with traditional and new lubricants, including mineral, alkylbenzene, and polyolester oils. In most cases a retrofit doesn't require a different/new lubricant for the system, it  enables the continued use of existing equipment, and it helps extend equipment life. Freon™ MO49Plus is non-ozone depleting and not subject to phaseout under the Montreal Protocol.
