Decentralised recirculating air cooling system that sets new standards in terms of dimensions, cooling capacity, acoustics and thermal comfort. The INDULVENT connect offers 3D ambient air conditioning: maximum cooling capacity, low level acoustics and highly effective induction characteristics result in above-average user satisfaction. It functions as a 2-pipe system for cooling and a 4-pipe system for combined heating and cooling mode. Additionally, the unit can optionally be operated with a supply air socket, allowing for flexible adaptation to specific ventilation requirements.
