VATIS UPDATE Article

Carrier, the United States, has announced that it sees the low GWP HFO refrigerant R1234ze(E) as the best long-term sustainable solution for screw chillers. Carrier joins a long list of major chiller manufacturers now offering R1234ze(E) solutions, but said that it will continue to provide HFC R134a chillers in all regions including Europe. In addition to Carrier, manufacturers already offering 1234ze chillers include Climaveneta, Airedale, Star Refrigeration, Cofely, Blue Box and Klima-Therm.

The US manufacturer considers R1234ze(E) as the long term sustainable solution for the next generation to come and the best alternative that supports the European 2030 F-Gas carbon dioxide (CO2) equivalent reduction goals. Carrier anticipates that customer demand for very low GWP HFO-1234ze(E) chillers will grow with the evolution of European and national phase-down regulations. It also sees the introduction of high leaving water temperature screw chillers combined with very low GWP HFO 1234ze(E) as a means of extending its heat pump offer.
