Precision 1234zeUK: Commercial refrigeration manufacturer Precision is to offer the low GWP HFO refrigerant R1234ze as an option in its foodservice equipment.

Following successful tests working with refrigerant manufacturer Honeywell, Precision is to offer the new refrigerant as an option across its refrigerated storage range, from under counter cabinets to blast chillers.

According to Precision, the foodservice industry has been looking for refrigerants that are greener than traditional HFC refrigerants but also safer than hydrocarbons. Classified as “mildly flammable” under ASHRAE’s A2L rating, R1234ze is considered by some to be a preferable option to the highly flammable hydrocarbons.

“We’ve been trialling Solstice ze for several months,” says Nick Williams, managing director of Precision.  “It performs as well as, if not better than, traditional refrigerants like R134a and hydrocarbon R290. It runs particularly well in high ambient conditions, which is ideal for the foodservice industry.

“HFOs like Solstice ze are more environmentally friendly than traditional refrigerants such as R134a and safer than hydrocarbons: they are the foodservice refrigerants of the future,” he added.
