Floor Induction Diffuser DISA-B Description The SCHAKO floor induction diffusers of series DISA-B belong to the group of air/water systems and are suitable, thanks to their induction technology, for discharging high loads using small conditioned external air flows and the energetic benefit of load discharge (heating/cooling) by the medium water. Advantageously, DISA-B are used for room-high glazed buildings without false ceiling and low storey heights. In heating mode, draughts caused by cold air drop and surfaces emitting cold at the façade can be avoided, and in cooling mode the DISA-B reduces...

Floor Induction Diffuser DISA-B Assembly The DISA-B series is suitable for horizontal assembly in false floors. Thanks to the adjustable legs and the mounting plates, the DISA-B can also be levelled from the room side, after completed assembly. The floor induction diffuser DISA-Bis particulary maintenance-friendly. Grille, register and plenum box are cleaned with an industrial vacuum cleaner or steam cleaner or by spraying it with Apmax (kPa) a non-aggressive cleaner.
