JWH/BH 020÷342 S/Y/P

Watercooled Heat Pumps for very high temperature hot water production with scroll compressors and plate exchangers.

The units are designed to produce hot water at very high temperature, in compliance with the most stringent directives on energy efficiency and respect for the environment. In addition to this, their flexibly interacts with all technological plant solutions defined for every type of building, be it residential, commercial or industrial.
These units are ideal for indoor installation and, equipped with a self-contained structure, they can reduce the overall dimensions to a minimum while at the same time making installation and maintenance operations easier.
Thanks to the high construction standard and the precise regulation system, the units are able to guarantee a very high efficiency both at the nominal operating point and in partial load conditions.
These characteristics are visible on the machine's working range which is among the most extensive on the market with the production of hot water leaving the condenser up to 80° C with evaporator water outlet temperatures up to 40° C.
The units are compliant to the ErP Regulation.
On request, units can be supplied with R513A refrigerant.
