For the extraction in the so-called ‘wet rooms’ we developed the ClimaRad MiniBox. This addition to the ClimaRad (HRV) ventilation unit has multiple connections to provide ventilation in the bathroom, kitchen and toilet. The ClimaRad MiniBox is energy-efficient and is the smallest extractor box currently available. The extraction box is automatically controlled based on moisture and CO2 levels, and also based on the time control when this is linked to the ClimaRad ventilation unit. This HRV unit in the living room and the ClimaRad MiniBox work together wirelessly.
