Summer­freshness
Cooling without a refrigeration system - Thanks to the particularly efficient adiabatic cooling on the exhaust air side of the Recocool system air-conditioning unit, a refrigeration system can be dispensed with in many cases. Thanks to the high evaporation capacity, wetting takes place with 100% fresh water. This results in great ecological and economic advantages.

«New» ventilation & hygiene unit for little money
The solution is called redevelopment. Our throwaway society has a tendency to remove old things and replace them with new ones. This can quickly become expensive in the case of "monobloc" ventilation units. But this is not necessary. Ingenious renovation solutions make it possible to carry out a cost-effective conversion. The increase in energy efficiency ensures an attractive payback period.

Air is our most important food. We inhale about 15 kg of air every day, 90% of it in closed buildings. Therefore it is necessary that the buildings are supplied with fresh air. Whereas the building envelope used to have natural breathing, the walls and windows of modern buildings need to be insulated for energy reasons. Natural air circulation is prevented. So that we do not have to do without good air nevertheless, we have the solution...
