Characteristics:
- R450A is a non-flammable, zeotropic HFO blend refrigerant developed as a low GWP alternative to R134a.
- R450A is an energy-efficient alternative when used in medium temperature applications.
- Lowest GWP (547) in class with no flammability.
Physical Attributes:
- ODP: 0
- GWP: 547
- Class/ Type: Zeotropic blend (A1)
- Refrigerant Kind: HFC/ HFO Blend
- Oil type: Polyolester Oil (POE)
- Glide: 0.4K
Performance:
- Suitable low GWP retrofit replacement for R134a in DX supermarket refrigeration applications, R450A delivers a comparable carbon footprint in medium temperature applications
- Polyolester oil is recommended with R450A to ensure adequate oil return
- The same POE oil as R134a can be used with minimal adjustment to TX valves
- The small glide of R450A is of no effect in most DX systems
- Slightly reduced capacity compared to R134a
- Highly efficient when used in systems designed for R450A
Features:
- 58% reduction of GWP compared with R134a
- Improved energy efficiency compared to R134a
- Similar performance to R134a, with slightly less capacity
- Suitable for retrofit or new installations
- Approved by most OEM manufacturers (check guidelines)
- Liquid or vapour charge
Applications:
Medium and high-temperature applications including:
- DX medium temperature refrigeration systems
- Heat pumps
- Air and water cooled chillers
- Vending machines and beverage systems
