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
