Ceiling cassette units in a compact Euro-grid format with EC fans and flexible control technology
The new generation of ceiling cassettes is equipped with state-of-the-art EC fans, allowing for stepless speed control. These provide high efficiency, particularly in partial load operation, ensuring draft-free cooling and quiet operation.
With an exceptionally low installation height of just 298 mm, the ceiling cassettes can be easily integrated into almost any ceiling void. The air is efficiently distributed via a round heat exchanger with a medium temperature of up to 70°C and is evenly released across all four sides below the ceiling.
The ceiling cassettes come standard with an internal condensate pump. Additionally, the 4-pipe version offers extra flexibility for controlling both heating and cooling in a single system. Optionally, fresh air supply can be integrated, or cooling for adjacent rooms can be expanded. Fault and operational conditions can be captured and processed via potential-free contacts.
