New HFO refrigerants available from Kirby

Kirby now has available HFOs designed to replace R404A, R507, R123 and R134a.

R452A is a non-ozone depleting, non-flammable HFO refrigerant blend designed as a lower GWP alternative to R404A and R507 in low and medium temperature applications. R452A closely matches R404A thermodynamic properties and performance and offers a lower compressor discharge temperature. This refrigerant is primarily used for transport refrigerated vehicles as they require a safe, non-flammable and low toxicity refrigerant, with the ability to work efficiently under a wide range of ambient conditions.

• R452A should only be liquid charged into a system to ensure correct refrigerant composition and system performance
• Non-flammable, A1 safety classification
• POE oil
• Used as a retrofit or new installation
• Is used in low and medium temperature applications

R1233zd is a non-ozone depleting, non-flammable HFO refrigerant, produced as a replacement for R123. It is primarily used in low to negative pressure centrifugal chillers, with better performance and improved efficiency compared to R123.  R1233zd is suitable for new equipment and NOT suitable for retrofit applications. For optimal performance, it is recommended to use valves and fittings with plastic sealing washers. Avoid using fibre washers as leaks may occur.

• Non-flammable, A1 safety classification
• Mineral oil (specific)
• Ultra-low GWP 1
• Innovative single component HFO

R1234ze is a HFO refrigerant designed as a low GWP alternative to R134a. Used in chillers, commercial air conditioning and as the secondary refrigerant in CO2 cascade systems in commercial refrigeration. Due to the flammability, it is essential to check equipment compatibility.  R1234ze Should only be used in systems specifically designed for R1234ze.

• Ultra-low GWP < 1
• Compressors must be charged with modified polyolester oils (check OEM guidelines)
• Not suitable for use in retrofit applications
• Liquid or vapour charge
