x-well central domestic ventilation – healthy thermal comfort for modern new-builds.

x-well® central domestic ventilation Healthy thermal comfort for modern new-builds.

Bring new freshness into your four walls.

Due to stricter building regulations, e.g. the energy saving ordinance (EnEV), new-builds are becoming more or less hermetically sealed buildings without natural air exchange to the outside. However, everyday activities, such as cooking, washing, or showering, as well as the air breathed by the residents, increase the humidity in the rooms. Without sufficient ventilation, the health risks to people and to the building arising from mould forming are increased. To ensure the minimum hygienic air exchange, it would be necessary to air throughout for approx. 10 minutes every two hours. How can this be achieved in reality?

This is where controlled domestic ventilation solves the problem. Domestic ventilation ensures you have fresh air and great thermal comfort. The Kermi x-well domestic ventilation systems are available as central or decentralised systems – for renovations in existing buildings as well as for new-builds.

x-well domestic ventilation

Healthy thermal comfort for modern new-builds.

Systems for domestic ventilation are standard today for all modern new-builds. Kermi x-well means you are always right up to date – both technically and with regard to the most recent building and energy regulations.

Saving energy while ventilating.

x-well domestic ventilation systems consume very little energy while working thanks to the high heat distribution. So in contrast to window airing, ventilation which is independent of the user is ensured, without heat being lost unnecessarily. This saves fuel and therefore hard cash.

Aesthetically pleasing and functional for optimal air.

The new Kermi x-well design air vents offer harmonious solutions for various installation situations in both suspended ceilings and also in dry construction walls. As flow-optimised source air vents, they contribute to a comfortable ventilation of the rooms.

Everything perfectly controlled.

With demand-led control, the air quantity is adjusted to current demand. (depending on the ventilation units' options characteristics).

x-well® S series

Central living space ventilation with heat recovery

The compact ventilation units in the Kermi x-well® S series with heat recovery offer comfortable and controlled living space ventilation. The volume flows can be controlled as required via the relative humidity of the exhaust air . The units (type dependent) have a humidity sensor integrated in the exhaust air . With this sensor, it is possible to control the volume flows according to demand through the relative humidity. The countercurrent heat exchanger made of polystyrene used for heat recovery is proving to be particularly efficient. In contrast to that, the integrated summer bypass provides support in the summer to ensure that no warm air gets inside the building. 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 cartridges.

Using a flat ventilation unit as an example, the S280, shows how it is possible to install the unit as well as the main duct system in the suspended ceiling. Here, manifolds/collectors and the ventilation ducts are encased in the bare concrete ceiling.

When retrospectively installing an x-well domestic ventilation system, it makes sense to integrate it into the floor construction. Here, the ventilation ducts are laid in the insulation layer. Ideal for renovation situations.

If the controlled domestic ventilation is used over several storeys, then the ventilation unit is connected to the manifold/collector via silencers and main duct pipes. There are three different options for integrating the ventilation ducts: in the suspended ceiling, in the bare concrete ceiling, or in the bare concrete ceiling.

x-well® F series

Central domestic ventilation with heat recovery

The x-well F series is the controlled domestic ventilation for upgrading. Thanks to the versatile installation options and due to its shallow construction depth, it is ideal for renovation and can easily be installed in drywalls and suspended ceilings.

The Kermi x-well® F series with heat recovery provides as compact ventilation units comfortable and controlled living space ventilation.  The volume flows can be controlled as required via the relative humidity of the exhaust air . The units have a humidity sensor integrated in the  exhaust air . With this sensor, it is possible to control the volume flows according to demand through the relative humidity. The countercurrent heat exchanger made of polystyrene used for heat recovery is proving to be particularly efficient. The white powder-coated (RAL 9003) housing made of sheet steel is heat insulated and soundproof. The removable front part provides easy access for service and maintenance work or for replacing filter cartridges.

x-well® brine/air geothermal energy exchanger

For temperature control of outside air. Preheating in the winter / cooling in the summer

Unlike the air, the ground has relatively constant temperatures. That way, the brine/air geothermal heat exchanger can preheat the outside air at low outside temperatures in the winter and keeps it frost-free. As a result, optimum operation for the ventilation unit can be assured even at temperatures below the freezing point. In the summer the ground temperatures are considerably cooler than the outside air. As a consequence, the outside air can be adequately tempered via the brine/air geothermal heat exchanger. In addition, the brine/air geothermal heat exchanger is an energy saving alternative to electric preheating coils thanks to the use of regenerative energies.
