We offer turnkey delivery of wastewater heat pump systems based on natural refrigerants. Our solutions are customized and tailored to our customers' individual needs for the most value-adding result.
For the majority of the year, wastewater is warmer than both seawater and air, making it an ideal heat source for a heat pump system that can produce district heating in a green, sustainable, and cost-effective way.
Stable energy supply
There are several advantages to reusing the energy in wastewater. Firstly, it benefits the district heating consumers, as the relatively high temperature of wastewater ensures a more stable energy supply. Likewise, it is positive for the aquatic environment, as lowering the discharge temperature of the treated wastewater brings it closer to the temperature of the aquatic environment into which it released.
How does it work?
Air collectors capture energy from the air, which is then transferred to a refrigerant in a heat exchanger. The refrigerant is compressed in the compressor to increase the temperature and transfer the absorbed thermal energy to water at a higher temperature. The hot water is subsequently sent out into the district heating network.
