Forty years of experience in the development and production of ventilation systems provide the basis for Zehnder's well-designed products and systems with many advantages: They are effective, energy saving, hygienic, user friendly and have perfectly matched individual components. From planning to maintenance: Zehnder Comfosystems are always a good choice.
Cross-flow, counter-current heat exchangers are standard equipment for Zehnder ventilation systems. They are therefore capable of transferring the heat energy of the used air to the fresh air. This heat transfer takes place through thin plastic plates according to the counter-current principle. The heat recovery level is approx. 90%, which saves approx. 40% of the heating costs.
The relative humidity in the building is optimised by plate heat exchangers, which is ideal when the air is dry in winter. The water vapour from the humid exhaust air "condenses" and is taken up by a membrane. The recovered humidity and heat are transferred to the fresh air without any transfer of smells or microbes.
