Solstice® ze Refrigerant (HFO-1234ze) from Honeywell, a leading global refrigerant brand, offers a new and more sustainable alternative to conventional refrigerants.

With ODP = 0 and GWP < 1, Solstice® ze has a Global Warming Potential approximately 99.9% lower than R-134a.
It is classified under ASHRAE Safety Class A2L and is compatible with POE lubricants.
The pure-molecule characteristics of Solstice® ze also make it suitable for use in flooded systems.
Applications of R-1234ze
R-1234ze can be used in energy-efficient refrigeration equipment and commercial air-conditioning applications, including systems used in supermarkets, commercial buildings, and other medium-temperature applications.
Typical applications include:
- Heat pumps
- Refrigerators
- Vending machines
- CO2 cascade systems
- Commercial refrigeration
- Commercial air conditioning
