Energy-efficient residential ventilation for loft mounting

Category: Tag:


A good indoor climate determines the health and well-being of the entire family and protects buildings and interior from moisture damage.

The HCH range of residential ventilation units has built-in RH sensors automatically adjusting air volumes in relation to the relative humidity in the home. This means that there is no need to wire the unit up to external sensors.

The HCH units are constructed with a new, light-weight aluminium counter flow heat exchanger developed and manufactured by Dantherm, which has an efficiency level of up to 95%.

The integrated control panel allows the user to adjust individual default settings such as manual or automatic control of ventilation speed. With an optional wireless remote control the user gets access to further control options such as away and night operation.

Energy efficiency class A or A+
The standard versions of HCV/HCH are rated as energy efficiency class A. By connecting an optional CO2 sensor in the kitchen-dining room or the bedroom, the HCV/HCH units will obtain energy efficiency class A+. The CO2 sensor is connected to the MVHR unit by means of the accessory control (HAC 1).
