COOLWEX »HPW« WATER/WATER heat pump


This system is one of the most effective heating systems. Ground/water is the perfect heating source because of its relative high temperature.


You can reach high COP (heating number) even over 5.0.

The ratio between heat pump capacity and electrical power for compressor is the highest, because of high relative temperature of heating source.


COOLWEX water/water heat pump achieve extremely high COP over the whole year.

All water/water heating systems offer very wide range of heating and cooling options, together with sanitary water heating.


Water/water heat pump needs constant flow of ground, surface or tehnology waste water. The needed flow dependson heating power and

temperature difference between water inlet and outlet.

Water/water heat pump
 All models have built-in compressor with newest »Copeland« Technology,
plate heat exchangers SWEP, Siemens regulation and other components of
the best in world recognized manufacturers. All models use environmental friendly refrigerant R407 C. All models have built-in heating circulation pump, 3-way switching valve and 3, 6 or 9 kW electrical heater in serial production.		 Serial Siemens regulator offers you to regulate 1 x mixing circuit, 1 x direct circuit, sanitary water heating, sun collectors, pool heating, cascade regulation of two compressors and much more…
We can also supply models with bigger heating capacities – HPW 22, 25 and tandem versions HPWT 30, 37, 49, 59, 67, 78, 89, 100 and 115 kW.
