General

CONDOR is a supply air ceiling system with adjustable discs. The spread pattern is infinitely flexible and can be adjusted as required without affecting the airflow, pres- sure drop or sound level. The supply air can be at over- or under-temperature. CONDOR is particularly suitable for applications where large supply airflows are required without high air velocities in the occupied zone, for example in laboratories, clean rooms, hospitals, catering kitchens and schools. The discs in the fi gure are arranged in a special pattern.

Technical description

Design

The supply air ceiling consists of a number of diffuser modules, equipped with discs, which are installed in a common backing box. The air diffuser modules are also equipped with the VariZon air distribution system to dis- tribute air uniformly.

Materials and surface treatment

The supply air ceiling is manufactured in galvanised sheet steel. The discs are made of ABS plastic and the VariZon® air distribution plates are made of polypropylene. The entire unit is painted with our pure white standard paint, RAL 9010. The unit is also available in other standard colours: Dusty grey 7037, white aluminium RAL 9006, jet black RAL 9005, grey aluminium RAL 9007 and signal white RAL 9003 (NCS 0500).

Special version

In addition to the standard sizes, this unit can be supplied in special dimensions and with different numbers of discs, etc. CONDOR is also available in galvanized finish. Please contact your nearest sales office for information.

Accessories

CRM. Commissioning damper with measuring unit.

Planning

The unit can be installed freely suspended or integrated in a suspended ceiling.

The recommended maximum under-temperature is 5°C.

The recommended minimum installation height above the floor is 2.7 m.

Installation

The backing box has a number of M8 pop nuts on top and a number of attachment eyes along the sides for sus- pended installation. The backing box can also be bolted directly to the building structure from inside the box. The diffuser panels are inserted into the backing box at an angle, with the VariZon®distribution plates facing the airflow, then laid on the grid. See Figure 1.

The dB(A) values are for rooms with normal acoustic s

absorption of 4 dB.

The dB(C) value is normally 6-9 dB’s higher than the s

dB(A) value. For more accurate calculations, see the calculation template in the chapter on Acoustics in the Technical Information section of this catalogue.
