Ceiling chests for niche installation

The optimum, invisible solution for offices, banks or hotels because of its small installation height. Thanks to the modern, energy-efficient EC motor, the installed fan is infinitely variable. This increases the user's comfort. The rectangular device air outlet is designed to accommodate adjustable air outlet grilles for an individual distribution of air. The air is filtered in the unit's air intake with a reclaimable plug-in filter. The internal tangential fan allows multiple airflow settings. The diagonally fitted copper-aluminium heat exchanger is designed for cooling medium temperatures of up to 80°C. The unit can easily be upgraded to a 4-pipe system through the installation of a heating register. The register connections can be mounted on either side of the unit in a condensate-insulated housing. A valve assembly for 2- and 4-pipe systems are available as accessories for cooling control.
