Ceiling units for installation in ceiling voids – The perfect, discrete solution

With their low installation height, these ceiling units are the ideal, invisible climate control solution for offices, banks, or hotels. The integrated EC motor ensures energy-efficient operation and allows for continuous fan speed adjustment, significantly enhancing comfort and user-friendliness. The rectangular air outlet is designed for adjustable air outlet grilles, enabling customized air distribution. A regenerable insert filter at the air intake efficiently cleans the air. The internal tangential fan provides multi-stage airflow adjustment for precise room adaptation. The diagonally installed copper-aluminium heat exchanger is designed for medium temperatures up to 80°C. With the option to integrate a heating coil, the units can easily be upgraded to a 4-pipe system. The coil connections are available on both sides of the condensate-insulated housing. A matching valve assembly for 2-pipe and 4-pipe systems is available as an accessory for precise cooling performance regulation.
