A ventilation system that does not meet these demands or is poorly designed will not be helped by modern construction methods and could indeed contribute to poor air quality in the home. Well insulated houses can suffer with mould growth within the fabric of the building if there is...

5 VR 400/700 DCV and DC are complete air handling units suitable for homes, smaller offices and similar premises. With EC-fan motors and a new regulation system the energy use is optimized to be able to meet the new regulations on energy management. Compared to AC-motors EC-motors maintain efficiency throughout the motor speed range when speed controlled and are therefore suitable to use in demand controlled ventilation units. Measurements show that an EC-motor reduces the energy use with up to 50% compared to a traditional voltage controlled AC-motor. To ensure optimal operation, the...
