Assembly Assembly The two long sides of the DID300B are each provided with two suspension holes or for L1 = 1500 4 holes are provided on each side. The assembly is installed on site using wire or metal hangers which must have the Building Authority certificate of approval. When the DID300B has been installed, 4 locking devices can be loosened with a screw driver (detail X) and the whole induction grille can be lowered down lengthways. The induction grille is supported by two safety cables. The coil is accessible when the induction grille is removed. The coil connections are on the outside of...

Installation The DID300B unit is fitted with a border extrusion which is suitable for the usual range of ceiling constructions. This ensures the best possible ceiling design. Installation in T-bar ceilings or closed ceilings Installation into grid ceilings Weight relative to the stability of the construction must be taken off the ceiling. Suspension holes are provided for this. The same also applies to preventing the units themselves from sagging. The DID300B can be installed on site at the ends using the support angles which are available as an accessory. The support angles are supplied loose...

Order details Specification text Support angles and flexible hoses are available as accessories for the DID300B unit. The active chilled beam type DID300B is suitable for dealing with high internal heat loads using a combination of air and water. It consists of the top plenum which serves as primary air duct and a diaphragm plate with nozzles in two longitudinal rows (different nozzle sizes are available). A coil is fitted underneath the primary air plenum and diaphragm plate. The induction grille below the coil is a perforated plate. The coil can be used either for heating or cooling (2-pipe...
