R-1234ze is a hydrofluoroolefin (HFO) refrigerant with a GWP of less than 1, representing one of the lowest environmental impact options available for refrigeration and air conditioning systems. This non-flammable refrigerant comes in two isomers: R-1234ze(E) and R-1234ze(Z), each with distinct pressure characteristics and applications. The ultra-low GWP meets or exceeds future environmental protection standards.
Performance and Safety Profile
R-1234ze(E) has a normal boiling point of -19°C and operates at lower pressures than many traditional refrigerants, reducing system stress. The refrigerant is classified as A1 for non-flammability, eliminating flammability-related safety concerns. Operating pressures typically range from 50-300 psi depending on application and ambient temperature, with excellent thermodynamic efficiency.
Industrial Refrigeration Applications
R-1234ze(E) is increasingly used in centrifugal chiller systems and high-temperature industrial refrigeration applications where its low pressure drop characteristics provide advantages. The minimal environmental impact makes it ideal for facilities with environmental compliance objectives. Compatibility with mineral oils and synthetic lubricants facilitates retrofit and new equipment installations.
