Enquire Now Brochure not available


The HCH residential ventilation units are primarily designed for 1-2 family houses. The units are supplied as packaged ventilation units complete with built-in demand-control and 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.

Key features

  • Demand-controlled ventilation with integrated humidity sensor
  • High-efficiency heat recovery
  • EC motors with extremely low energy consumption (low SPI)
  • Easy-to-install solution with pressure pipes for air volume measurement and adjustment on the unit
  • HCH models are suitable for installation on uninsulated attics
  • Separate HCH control panel included, plus a 2m cable

HCH models

The HCH residential ventilation units are horizontal models designed to be fitted in the loft or on the floor of a plant room. They fulfil the ventilation requirements of houses up to app. 475m<sup>2</sup>, depending on national requirements and the actual pressure loss in the installation.

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.
