R450A Refrigerant Gas Product Features:

– Azeotropic refrigerant blend containing R134a and HFO1234ze.
– Refrigerant can be charged from either liquid or vapour phase.
– R450A Refrigerant cylinders have dual port valves, making liquid offtake easier.
– Non-flammable with a safety classification of A1.
– Compressors must be charged with polyolester oils, contact the compressor manufacturer for more information.

– Suitable replacement for R134a, with comparable operating characteristics and similar performance.
– 58% lower GWP to R134a.
– Lower discharge temperature than R134a.
– Higher coefficient of performance at higher ambient temperature providing energy savings.

Buy  Quality R450A Refrigerant Gas.

Application: Medium and low temp refrigeration applications, appliances. Retrofitting R-12 or blends used to previously retrofit R-12 systems.Performance: Similar capacity and efficiency to R-12. Higher pressures, similar to R-401A and R-409A

Lubricant: R-450A requires polyolester (POE) lubricant. Follow manufacturer’s recommendations for changing mineral oil to POE.

Characteristics

• 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

How R-448A compare to R-404A?

R-448A has a similar cooling capacity with improved energy efficiency compared to R‑404A. In many cases the compressor discharge temperature will not be a concern but for some low temperature applications, under the same operating conditions,R‑448A will exhibit a significantly higher compressor discharge temperature than

R‑404A which, in a retrofit situation, may need to be managed.Full theoretical performance comparisons at customer specified conditions are available from Lunxabrefrigeration on request.

Packaging and Supply

  • Lunxabrefrigeration supply R-448A in 10kg, 19kg or 53kg returnable cylinders.
  • Conforms to AHRI 700-2016 specifications.
