In-pipe Heat Exchanger

Wastewater contains thermal energy which can be recovered. The HUBER TubeWin Heat Exchanger is designed to withdraw sewage from the sewer, screen it, pump it through above-ground Heat Exchangers to recover the energy, and then return it back into the sewer.

The high thermal energy of municipal wastewater is transferred to a carrier medium by means of heat exchanger elements which are mounted directly on the sewer bottom. This technique permits that the energy can be used by a heat pump. The heat exchanger elements do not need extra space as they are installed inside the sewer.

Economic use of municipal wastewater as an energy source and heat sink.
