Lower GWP R515B offered on water-cooled heat pump chillers

Aermec's WFGN and WFGI water-cooled chiller and heat pumps will now be available with the option of using R515B, a lower GWP HFO refrigerant that has an A1 non-flammable classification.

Originally both series of chillers were developed with optimised compressors and heat exchangers, enabling them to use R1234ze, a low GWP A2L (mildly flammable) refrigerant and achieve a higher SEER value.

But following extensive R&D, customers can now use R515B, which is a non-flammable option to R1234ze.

R515B is an azeotropic combination of R1234ze and small amounts of R227ea which suppresses the flammability. Tests confirm that R515B can achieve similar performance compared to R1234ze which both the WFGN and WFGI were originally designed for.

The WFG and WFGN are designed for indoor installation and suitable for large sized services in commercial, industrial and residential buildings.
