These units have become very popular for all types of retail, office or commercial applications due to their high degree of flexibility. A cassette unit recesses into a false ceiling leaving only a decorative panel on view. Air is drawn in through the centre of the panel into the unit where it is filtered and cooled or heated as necessary before being supplied back to the room via four edge slots.

Cassettes distribute very effectively over large areas, making them ideal for open plan shops or offices. Cassettes are also ideal for refurbishment projects or installation in occupied spaces as they are relatively quick to fit and disruption is kept to a minimum.

Cassette can be part of single split, multi-split or larger VRV systems and range from 3.5 kW to 13 kW in capacity, each.
