Ceiling units for installation in ceiling voids – The perfect invisible solution

With a compact installation height, these ceiling units offer an optimal, discreet solution for offices, banks, or hotels. The rectangular air outlet is designed for the integration of adjustable air outlet grilles, allowing for customized air distribution.

The air is filtered at the air intake of the unit via a regenerable insert filter. The internal tangential fan enables multi-stage adjustment of the air volume. The diagonally mounted copper-aluminum heat exchanger is suitable for medium temperatures of up to 80°C.

By installing a heating coil, the units can easily be upgraded for a 4-pipe system. The coil connections are integrated on both sides within the sweat-water-insulated housing. For regulating cooling performance, a valve assembly for 2- and 4-pipe systems is available as an accessory.
