R452A Opteon™ XP44 HFO Refrigerant
R452A, also known as Opteon™ XP44, is a lower-GWP HFO refrigerant blend used as a replacement for R404A and R507 in low-temperature transport refrigeration applications.
Designed to closely match the performance of R404A, R452A is suitable for transport refrigeration systems where low discharge temperatures are required. As a zeotropic blend containing R32, R125 and R1234yf, R452A must be charged from the liquid phase to maintain accurate refrigerant composition during service and installation.

Safety & Documentation
R452A must be handled by appropriately licensed refrigeration and air-conditioning technicians. As a zeotropic refrigerant blend, it must be charged from the liquid phase to maintain accurate composition during installation and service.
A-Gas notes that compressors must be charged with polyolester oils, and technicians should contact the compressor manufacturer for system-specific oil compatibility guidance. Store cylinders in a cool, dry and well-ventilated area, away from direct sunlight. Used cylinders should be returned through the A-Gas wholesale partner returnable cylinder fleet.
Always refer to the current A-Gas Safety Data Sheet and equipment manufacturer guidance before use.
A-Gas R452A Opteon™ XP44 is a practical lower-GWP refrigerant option for compatible transport refrigeration systems where a non-flammable A1 replacement for R404A or R507 is required.
