Cassette placement starts with the occupants, furniture and facade loads. We select panel, capacity and controls together, then plan where the air reaches the room and where it should avoid a direct draught.
Technical reference
- Families: FDT / FDTC — FDT four-way; FDTC compact four-way cassette
- Example capacity: 2.8 / 3.2 kW — FDT28KXZE1 cooling / heating at ISO-T1 conditions
- Example casing: 236 × 840 × 840 mm — FDT28KXZE1; standard panel is separately 35 × 950 × 950 mm
- Air distribution: Draft Panel / Airflex — Depends on a compatible indoor-unit, panel and controller combination
The panel is part of the comfort decision
Draft Panel / Airflex supports reduced direct draught on compatible FDT and FDTC combinations. It is not standard equipment on every cassette. We identify panel and controller codes in the proposal and match vane directions to desks, seats and glazing. The person sitting directly below the unit deserves attention alongside the room’s perimeter load.
Allow for everything above the ceiling
The unit’s height is only part of the installation space. Suspension, insulated pipes, drainage and connection access also need room. We coordinate the panel with lights, sprinklers and ventilation terminals. Filter maintenance should remain possible without unnecessarily closing the occupied space.
Drainage and noise need commissioning checks
Condensate drainage must follow the selected model’s pump and pipe conditions. Incorrect gradients and connections can create problems behind a finished ceiling. For acoustic assessment, we consider the real airflow needed at design load rather than only the lowest catalogue fan-speed value. We adjust fan and vane settings around the occupied room.
A fresh-air connection needs a ventilation design
An available fresh-air connection does not automatically supply the room’s required outdoor-air quantity. Airflow, filtration and the additional temperature and humidity loads require separate calculations. Where necessary, we coordinate ventilation with VRF while preserving the cassette’s main role in room heating and cooling.
Our selection checklist
- Check the ceiling module and clear installation depth
- Specify compatible panel, controller and sensors
- Direct air around the actual seating layout
- Resolve drainage, filter access and outdoor-air demand
Frequently asked questions
Is an Airflex indoor unit alone sufficient?
The panel and controller must also be compatible. We confirm the indoor-unit, panel and control codes together before ordering.
Does a cassette supply fresh outdoor air?
Room-air circulation and outdoor-air ventilation are separate requirements. If a compatible fresh-air connection is used, its airflow and conditioning load must be designed.
