heat recovery unit & systems at exodraft


To ensure optimal safety and efficiency the exodraft  CHR P/P-S-heat recovery unit must always be used with original exodraft accessories:

3-Way-Mix Valve

The mixing valve ensures that circulation will only take place to the collection tank when the water has reached the desired temperature.
Sensor til varmemængdemåling
If the water does not have the desired temperature, it is recirculated to the heat exchanger until the desired temperature is reached.

Motor for Mix Valve

Motor to control a 3-Way- Mix Valve.

Safety Temperature Cut-off

Safety valve

Temperature gauge

Temperature gauge to control an additional collection tank.

Equalization Valve

Equalization valve with integrated flow meter and gauge glass.

Sensor for heat quantity measurement

A flow meter, which when used in conjunction with the EHC controller, measures the amount of recycled energy.

Product Range
