In-pipe Heat Exchanger

Wastewater contains thermal energy which can be recovered. The HUBER ThermWin® system 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.
Because our Heat Exchanger will be installed above-ground instead of a direct sewer installation, there are several benefits regarding installation and maintenance effort.

Due to the modular design the Heat Exchanger can be customized for any project size. Dependant on it’s size, this system may generate some hundreds kilowatts of “green” heating power in connection whth a heat pump.
