Healthy thermal comfort for every living situation. Contemporary construction or energy efficient renovation and the specifications of the EnEV require a high level of energy efficient insulation. That is why central residential ventilation systems are now standard in passive houses, low-energy houses, and housing renovations. x-well residential ventilation supplies rooms with fresh air around the clock and thus permanently creates hygienic thermal comfort and a pleasant level of humidity, not too high. By filtering dust and pollen, your own four walls also become a place of well-being for allergy sufferers. As no window needs to be opened, street noise stays outside, as do pollen and allergens. We only install external filters of the highest possible filter class ePM1 according to ISO 16890 in all central ventilation units. During air exchange, odours are naturally also removed from the kitchen, bathroom, and WC. Apart from that, x-well residential ventilation systems consume very little energy while working due to the high heat distribution. So in contrast to window airing, no heat is unnecessarily lost.
The design air vents fit in with any interior design furnishings.

The x-well S-series with heat recovery offers a wide range or compact ventilation units for comfortable and controlled residential ventilation. The volume flows can be controlled as required via the relative humidity of the extract air and they have a humidity sensor integrated in the extract air (depending on the unit configuration). 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.

x‐well hygienic is an electronic air filter. It was developed to improve the air quality of the supply air and to protect the health of the people who are in the building. The electronic air filter is based on the principle of separating particles present in the air by their electrical polarisation and their subsequent fixation on opposing, differently charged metal surfaces that form numerous strong electrical fields. As a result, pollutant particles become electrically charged and are attracted and held in place as if by small magnets. The electronic filter effectively stops particles of category ePM1 (fine dust), soot, pollen, biological substances, and viruses that are on the particles.
Benefits of the x-well hygienic air filter
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. Apart from that, the brine/air geothermal heat exchanger is an energy saving alternative to electric preheating coils thanks to the use of regenerative energies.
Characteristics
Heatable air vent for use in the supply air area. Suitable for installation in the ceiling and in the wall. Own heating output control depending on the air quantity through PTC heating element. For ventilation pipe flat. With adapter also for round pipe. Version SEA500 without electric heating element can be used for the extract air with an optional filter .
