Heat recovery

Air that is extracted via ventilation systems often contains a lot of heat. We do not want to let this heat go to waste and aim to recover as much of it as possible. We do this by using various types of heat exchanger. We recover the heat from the extract air and use it to heat the cold air from the outside.

We offer several different types of high-efficiency heat recovery units. This allows us to offer the most optimal solution at the same time as protecting the Earth’s resources.


On a cold winter day with an outdoor temperature of -20 ºC, we can use a rotary heat exchanger to pre-heat the outside air to 15 ºC, thus saving a lot of energy.
