Water condensed modulating chillers with high performances MHW

Water condensed modulating chillers with high performances

Continuous capacity modulation

Max efficiency at partial loads

Extreme low-noise with Hi-Box®

Easy accessibility with Hi-Rail®

All compressors are installed in the brand new Hi-Box® for a very low noise emission and can be pulled out of the frame for easy maintenance thanks to the Hi-Rail® solution.

MHW is the last generation of water condensed chillers, designed with a combination of ON/OFF and BLDC inverter driven compressors.

Thanks to a dedicated control software, developed inside HiRef, MHW units provide a continuous modulation of the cooling capacity, don’t require buffer tanks and have reduced start-up currents.

The BLDC inverter driven compressors are frequency modulated in order to reach the highest cooling capacity or the highest energy efficiency in every single working point.

MHW can be connected to all Polymorph® by HiRef

MHW can be connected to all Polymorph® by HiRef for the highest flexibility of your systems.
