The basic compact ventilation for your home
The iV-Light ventilation system is designed to ventilate living rooms and bedrooms in single and multi-family houses, as well as rooms in public facilities and work rooms in office buildings. It is suitable for both installation in new buildings and for retrofitting in existing buildings. Installation is carried out in the exterior wall. The ventilation unit iV-Light comprises a wall sleeve into which a thermal accumulator insert is installed, as well as an inner cover and a weather protection grille as an exterior closure. The thermal accumulator insert contains the ceramic thermal accumulator and inVENTron®. The flow-optimised design of inVENTron®, the two guiding vanes with embedded reversible fan Xenion®, ensures optimum heat recovery with maximum air flows through the thermal accumulator.
The ventilation unit operates on the principle of heat recovery by changing the direction of the fan. The integrated thermal accumulator charges itself with heat energy from the room's air as it flows to the exterior (extract air). After 70 seconds, each Xenion reversible fan changes direction and releases the stored heat energy into the incoming outside air (supply air).
For this principle to work correctly and to ensure the room’s pressure stability the incoming air and extract air volumes must match, i. e. two iV-Light ventilation units are required. These are operated in pairs in pushpull operation: One ventilation unit works in supply air mode while the other works in extract air mode at the same time.
The standard length of the wall sleeve is 495 mm. For thicker walls, there is the option of ordering a wall sleeve with a length of 745 mm. Both versions can be trimmed on site.
