Decentralised recirculating air cooling system that sets new standards in terms of dimensions, cooling capacity, acoustics and thermal comfort. The INDULVENT ec offers 3D ambient air conditioning: maximum cooling capacity, low level acoustics and highly effective induction characteristics result in above-average user satisfaction.
The INDULVENT ec only responds to the actual cooling demand of the interior, thus avoiding unnecessary energy losses. The use of energy saving EC technology and variable flow rates, adapted to the actual cooling load, ensure high energy efficiency at low operating costs.
Dimensions no larger than those of standard air diffusers allow the INDULVENT ec to be integrated into all commonly used ceiling systems. Different designs and numerous special solutions offer interior designers and architects greater creative freedom than is found with conventional recirculating air cooling systems.
Decentralised recirculating air cooling system with a cooling capacity of up to 2600 watts for maximum thermal comfort. The hinged front panel enables maintenance and cleaning work to be carried out quickly and easily from within the room. Integral Vent-BUS technology supports efficient, user-focused operation.
The energy saving, acoustically optimised EC fan draws ambient air into the casing and cools it via the integral ring cooler. The cooled ambient air is then returned to the room via the front panel, which features highly inductive air guide vanes. The advantage of combining a recirculating air cooler with inductive air injection is the significantly higher level of thermal comfort. In contrast to conventional systems, which blow supply air straight into the room without mixing it thoroughly with ambient air, the recirculating air cooler creates a pleasant, draught-free ambient air flow, as is typical of Kiefer products.
A condensate pan with float switch and a low-noise condensate pump are integrated inside the casing to ensure operational reliability. This means any condensate that forms can be easily and safely discharged via a condensate line. The supply air flow rate and associated cooling capacity are regulated according to the requirements of users and of the room in question. The integral Vent-BUS technology enables master/slave operation without any further outlay for control equipment. In conjunction with a remote switch, it is even possible to set up single room control.

The centrifugal fan draws warm ambient air into the unit through the central air intake in the front panel. The air flows through a filter fleece in the intake duct to protect the internal components from dust and dirt.
The INDULVENT ec casing is no larger than that of a standard air diffuser and can be easily integrated into all common ceiling systems. The RQF version enables suspended installation where there is no suspended ceiling, without any reduction in comfort levels.
The INDULVENT ec complies with the hygiene requirements of air handling systems to VDI 6022. The front panel can be opened without tools via the standard folding hinge. This makes the casing, filter, fan, heat exchanger, condensate pan, etc. easily accessible for cleaning.
