R1234ze Refrigerant is an ultra-low Global Warming Potential (GWP) HFO refrigerant designed for commercial and industrial cooling applications. With a GWP of less than 1, R1234ze offers an environmentally responsible alternative to higher-GWP refrigerants while delivering reliable performance in chillers, process cooling, and specialized refrigeration systems.
R1234ze is commonly used in centrifugal chillers, air conditioning systems, heat pumps, data center cooling, industrial process cooling, and as a foam-blowing agent. Its A2L safety classification (mildly flammable, low toxicity) makes it suitable for systems specifically designed or approved for A2L refrigerants.

Important Information
R1234ze is an A2L mildly flammable refrigerant and should only be used in equipment specifically designed or approved for A2L refrigerants.
Do not substitute R1234ze for R134a or other refrigerants unless the equipment manufacturer specifically approves the conversion.
Use only with compatible POE lubricants and components.
Installation and servicing should be performed by qualified HVAC/R technicians following all local, state, and federal regulations.
