Ceiling cassette and ceiling-mounted unit compared
Efficient climate control with fan coil units – suitable for any ceiling configuration
Whether integrated into grid ceilings or surface-mounted, there is a suitable solution for every ceiling configuration.
The KaCool D AF is a ceiling cassette designed specifically for grid ceilings (e.g. Euro grid) to provide efficient and discreet heating and cooling for a comfortable indoor climate. If the air conditioning technology is mounted visibly beneath the ceiling, the KaDius ceiling-suspended unit offers clear advantages: a 360° air outlet, concealed connections, and an architecturally refined design.
This comparison shows which of the two fan coil units is better suited to your project
KaCool D AF
The ceiling cassette KaCool D AF has been designed for suspended ceilings and fits perfectly into Euro grids of 625 x 625 mm or 900 x 900 mm – available in any RAL colour and with an optional metal front panel.
KaDius
The KaDius can be installed just below the ceiling as a ceiling-suspended unit or integrated as a free-hanging unit within the room. Its outer casing can be easily customised.
