x-well® S-series

Compact ventilation units for comfortable and controlled residential ventilation in new builds.

The x-well S-series with heat recovery offers a wide range of compact ventilation units for comfortable and controlled residential ventilation. The volume flows can be controlled in accordance with demand based on the relative humidity of the extract air. For this purpose, the units have a humidity sensor integrated into the extract air line (depending on the unit configuration). Using this sensor, it is possible to control the volume flows according to demand based on the relative humidity. The countercurrent heat exchanger is made of polystyrene and serves as a really efficient heat recovery solution. Conversely, the integrated summer bypass helps to prevent any warm air from entering the building in the summer. The white powder-coated (RAL 9003) housings made of stainless steel are heat insulated and soundproof. The removable front part provides easy access for service and maintenance work or for replacing filter cassettes.

Central residential ventilation system with heat recovery for use in detached houses

The units from the x-well S-series have been designed for central controlled ventilation of houses and apartments. A generously proportioned heat exchanger is used to transfer thermal energy from the extract air to the outside air. The well-dimensioned fans generate minimal sound emissions and are extremely efficient. 

The x-well S-series with heat recovery offers a wide range of compact ventilation units for comfortable and controlled residential ventilation. The volume flows can be controlled in accordance with demand based on the relative humidity of the extract air. For this purpose, the units have a humidity sensor integrated into the extract air line (depending on the unit configuration).

Installation in the raw concrete ceiling

Using the S280 flat ventilation unit as an example, this video shows a possible installation scenario that involves placing the unit and the main duct system in the suspended ceiling. Here, the manifolds/collectors and ventilation pipes are encased in the raw concrete ceiling.

Installation on the raw concrete ceiling

If you are retrofitting an x-well residential ventilation system, it makes sense to integrate it into the floor structure. Here, the ventilation ducts are laid in the insulation layer. Ideal for renovation situations.
