Opteon™ XP44 (R-452A) Refrigerant

A New Generation Refrigerant Replacement for Industrial and Transport Refrigeration

Opteon™ XP44 (R-452A) refrigerant is a non-ozone depleting, low global warming potential (GWP) hydrofluoroolefin (HFO) based replacement for R-404A and R-507 refrigerants. It can be used in new commercial refrigeration equipment and for the retrofit of existing systems.

Opteon™ XP44 is well-suited for use in direct-expansion (DX) chillers, as well as for commercial systems that provide low- and medium-temperature transport DX refrigeration, such as refrigerated trucks, refrigerated vans, and reefer containers. It also can be used in low- and medium-temperature commercial and industrial DX refrigeration systems.

Features and Benefits

Opteon™ XP44 is approved and adopted by major commercial refrigeration equipment manufacturers. It offers a similar compressor discharge temperature and mass flow rate of R-404A and R-507.

Benefits of using Opteon™ XP44 as an R-404A or R-507 replacement in commercial refrigeration systems include:

  • Low GWP: 45% reduction compared to R-404A/R-507
  • Compatibility with existing equipment designs and lubricants
  • Eliminates the need for thermal expansion valve (TXV) adjustments
  • Can be topped off after leaks
  • Matches discharge temperature of R-404A and R-507
  • Safe and nonflammable
