Description

Square ceiling diffusers type ADLQ (aluminium) are ideal for flush mounting in ceilings. They are suitable for use in rooms with heights up to 4.00 m.The recommended supply air temperature differential is -10K. Ceiling diffusers can be used both for supply and extract ap-plications.With a fixed blade arrangement the ceiling diffusers are mainly suitable for horizontal discharge. Specially developed ancillar-ies and plenum boxes, with optional flow rate control dampers, are available to ensure optimum discharge characteristics.

Construction • Dimensions

ConstructionThe face section of the type ADLQ diffuser consists of a pe-ripheral border, fixed air control blades and a centre cone. The diffuser face section is fitted or removed by means of a central fixing screw. The screw head is then covered with a decorative cap. Types ADLQ are available as a diffuser face complete with plenum box and side entry spigot, or with the following ancillaries:

-...-A face section only -...-AR with rear mounting ring-...-CK with opposed blade volume control damper adjustable from diffuser face -...-C with double flap damper adjustable from diffuser face The use of versatile ancillaries for standard or duct mount-ing subframes or for installation in vertical ducts, results in great flexibility in installation for this type of diffuser. For easy adjustment of volume flow rate the plenum box is equipped, if required, with a test point for measuring pressure and a volume control damper which can be adjusted by a cord. The plenum box with side entry spigot can be used with vari-ous TROX air diffusers providing the combined technical data is taken into account.

Installation • Assembly • Materials

Installation • AssemblyType ADLQ ceiling diffusers can be adapted for use in almost all situations using the accessories available. All sizes are suit-able for mounting flush with the ceiling.

The plenum box is suspended on wire or straps using the holes provided. The seal is fixed to the edging of the plenum box.The diffuser face is fixed to the plenum box by the centre screw and the cross bridge provided.

If a vertical rigid duct is provided on site the diffuser can be fixed by means of a cross bridge and centre screw, or directly to the neck of the diffuser, e.g., by self-tapping screws. For these types of fixing the AR can be used. A duct mounting subframe can be supplied for constructions without plenum boxes. The following examples show the various types of installation.

Materials ADLQThe diffuser face is in extruded aluminium sections. The rear ancillaries are in formed sheet steel. The surfaces are phosphate treated and black stove enamelled .
