Dantherm HCH 5 – residential ventilation unit
Attic-mounted home ventilation units
The HCH residential ventilation units are primarily designed for 1-2 family houses. The units are supplied as packaged ventilation units complete with a control panel. The residential ventilation units are fitted with highly efficient counter-flow heat exchangers which are optimised to a very high efficiency level thus achieving a very low specific fan power (SPI value) for the entire unit.

All HCH models have duct connections at the ends and service access at the front. Electrical connection is at the end of the unit facing the fresh air – right-hand – side. The ducts connected to the home (supply and extract) are always on the left-hand side of the unit. The condensation drain is located at the rear of the unit.
