Solstice® ze (R-1234ze)

Solstice® ze (R-1234ze) is an energy-efficient, ultra-low GWP refrigerant alternative to R-134a in air-cooled and water-cooled chillers for supermarkets and commercial buildings, as well as in other medium temperature applications.

Solstice® ze is an energy-efficient, ultra-low GWP refrigerant alternative to R-134a in air-cooled and water-cooled chillers for supermarkets and commercial buildings, as well as in other medium temperature applications such as heat pumps, refrigerators, vending machines and CO2 cascade systems in commercial refrigeration. Its GWP of less than 1 is 99.9% lower than R-134a.
