FUNCTION AND USE

The curved ceiling slot diffuser type DSC-CURV is suitable for use in rooms 2.6 to 4 m high. The air deflection blades adjustable from below allow a varie-ty of throw adjustment options. Thus, the air throw pattern can be adjusted from a vertical throw in heating mode to a horizontal throw in cooling mode. In cooling mode, a one- or two-way air throw pattern can be set. A one-way air throw pattern in "outside" direction is preferred. The blades pro-duce a stable air jet. This achieves high induction while the velocity and temperature difference of the supply air jet are effectively reduced. Due to the central housing of the blades, the free cross-section is always the same. Accordingly, when the blades are adjusted, the pressure loss and sound power level remain constant. A subsequent change of the air throw pattern on site is possible at any time. If the desired blade position is specified in the order, it will be set at the factory. The large free cross-section allows a great-er volumetric flow compared with other slot diffusers. The stable air jet and high induction mean that the DSC-CURV slot diffuser can be used in cooling mode up to T0 ≤ -8 K. The resistance created by the blades ensures that the supply air is distributed equally across the whole length of the slot diffuser. The ceiling slot diffuser can be manufactured as 1-, 2- or 3-slot model and is available either as single piece or in band design. In addition, it can be combined with the DSC ceiling slot diffuser. Due to the stable air throw pattern, the ceiling slot diffuser can be also used in VAV systems from 100 to 40%. MODELS

The return air diffuser has a perforated sheet instead of the blades. The sheet can be easily cleaned from below through the slot. In order to clean the above located volume regulation more easily, the perforated sheet is always interrupted in the area of the connecting piece. * EÖB = installation opening width

FASTENING METHODS

Permanent connection (-FV)

In the permanent connection, the slot diffuser and the ple-num box are permanently connected to one another (4 rivets per unit). Clamp fastening (-KB) in mounting position

Assembly instruction The clamp straps are delivered loose. Introduce the screw through the bore into the blade and screw it down with the clamp strap. Position the clamp straps in longitudinal direction and intro-duce them into the ceiling together with slot diffuser (see in-stallation position). Then rotate the clamp strap by about 90° by rotating the screw and lower it over the slot diffuser profile (see clamping position). Tighten the screw until the slot diffuser is firmly locked at the ceiling.

Band design (-Band)

When the ceiling slot diffuser type DSC-CURV is designed as a band, the total length BL is assembled from lengths 1000 mm or 1500 mm. The difference pieces <1500 mm to >400 mm are fitted with a plenum box. The difference pieces <400 mm are supplied as dummy pieces without plenum box. A different band division is possible after consultation and when required by the customer. To give the impression of a continuous frame, lateral front end pieces can be fitted. The end pieces are supplied loose in pairs. End piece on both sides
