Scroll chiller uses HFO1234ze for the first time
Andalusian manufacturer Keyter is to use Honeywell’s HFO refrigerant R1234ze in a commercial scroll chiller for the first time.
Keyter’s new Helvetia scroll chiller employs the new Danfoss DSG scroll compressors, which have been optimised for use with the low GWP HFO refrigerant.
For the first time, the DSG compressors allow a medium pressure fluid like R1234ze to be used in a high pressure chiller without compromising the performance. The adoption of these scroll compressors in Keyter’s product range increases is said to increase energy efficiency when compared to models utilising R410A or R454B, while also offering the same cooling capacity.
These compressors are also available with high temperature models, making them a viable choice for heating applications.
