Cool heads in classrooms
Following the completion of the comprehensive renovation of the St. Karli school building, school operations resumed in August 2023. The 12 classrooms and various group rooms are ventilated using three RECOCOOL® system units. These are characterised by their compact design and high evaporation efficiency.

Ventilation units with a recirculation system were used for the other rooms, stairwell, toilet facilities and corridors. The HABITUShygro ventilation unit was used for the nursery school. This ensures a high level of heat and moisture recovery with the enthalpy counterflow exchanger.
