Ventilation – Advice

  • Ventilation units with DHW heat pump

    In ventilation units with a DHW heat pump, the extract air is routed centrally through the unit from the individual rooms and the supply air is fed in on a decentralised basis. They also supply domestic hot water.

    Ventilation units with heat recovery

    In ventilation units with heat recovery, up to 90% of the latent heat in extract air is recovered by a countercurrent heat exchanger. The compact units fit in any basement or utility room and are also suitable for multi storey apartment buildings. Special versions for smaller apartments are also available.

    Demand-dependent ventilation units without heat recovery

    In individual rooms, such as kitchens or bathrooms, demand-dependent ventilation units provide automatic ventilation. They have an integral humidity sensor that regulates the humidity in the air independently of the ventilation unit. Stale air is routed outdoors via an integral extract air fan. Fresh air is drawn in via vents in the living area, and the entire dwelling is ventilated subject to demand.
