2 Function and use I Models FUNCTION AND USE Since multi-purpose halls have many different uses, great demands are placed on their air-conditioning and ventilation requirements. Since both sporting and cultural events are held in these halls, requirements with regard to supply of air volumes and temperature differences between supply and room temperature also change. The long throw nozzle grille type WGA has been specially developed to cope with these different requirements. The advanced and well designed construction of the grille allows high throw speeds at low noise levels. The high throw speeds result in deep penetration of the room to be ventilated. This ensures that fresh air is circulated throughout the whole room and not just near the supply air grille itself. A further advantage of the long throw nozzle grille is that the entire air jet is divided into a large number of individual jets, thus resulting in a high level of induction. The temperatures and velocities of the individual jets are very quickly reduced. This means that on the one hand the supply air does not drop into the occupied area in cooling mode and, on the other hand the air does not rise too fast towards the ceiling in heating mode. The long throw nozzle grille type WGA-Q-V0-... with individually manually adjustable nozzles allows a diverging air jet (pivoting range 45 ). To achieve an even greater throw for cooling applications and effective, energy saving room heating for heating applications, the long throw nozzle grille type WGA- Q-V0-... has been designed with individually or jointly adjustable nozzles. In the WGA-Q-VG-..., WGA-Q-VE-... and WGA-Q- VT-..., the nozzles are fitted to a pivoting faceplate which can be adjusted manually, electrically or by means of a thermocouple (pivoting range 34 ). In the model with thermocouple, at a supply air temperature of 20 C or lower the nozzles of the WGA- -VT- are in the cooling position with throw direction diagonally upwards (max. angle 17 ). At a supply air temperature of 35 C or higher, the nozzles of the WGA- -VT- are in the heating position with throw direction diagonally upwards (max. angle - 17 ). In the temperature range between 20 C and 35 C, the nozzle rows are adjusted linearly. The long throw nozzle grille is available in models WGA-R-F0-..., WGA-R-V0-..., WGA-R-VG-..., WGA-R-VE-... and WGA-R-VT-... for direct installation in round ducts. At an extra charge, bars can be fitted to the faceplate as ball-impact guards. An integrated hit-and-miss damper is available for simple air volume regulation.

MOUNTING Screw mounting (-SM, standard) -- Screws must be provided on site Concealed mounting (-VM) (-VM, only possible for WGA-Q- F0... and WGA-Q-V0-...) -- with VM pole brace Number of nozzles WGA-Q- L H Number of nozzles WGA-R- L H At an extra charge, a plenum box can be mounted (only available without hit-and-miss damper). The damper in the spigot of the plenum box (at an extra charge) serves for easy air volume regulation. All models can be used in 100% to 40% VAV systems. The installation of the WGA-R-... in spiral ducts must take place free of stress. Avoid using unround or deformed spiral ducts, in order to protect the grilles from distortion.

28 Specification texts I SPECIFICATION TEXTS Long throw nozzle grille type WGA-Q-F0- particularly suitable for air-conditioning of high and large rooms such as multipurpose halls. High-induction supply air intake through several nozzles of high throw speeds at low sound power level, to achieve long throws and efficient throw pattern through optimum nozzle shape. High flexibility through a wide range of installation options. Installation in walls, ceilings, plenum boxes and ducts. Cooling and heating modes are possible. Suitable for use in 100% to 40% VAV systems. Housing consisting of sheet steel painted with a high-quality powder coating to a RAL colour (RAL 9010 [white, standard], RAL 9005 [black], RAL 9006 [white aluminium], RAL 9007 [grey aluminium] or a freely selectable RAL colour). Fixed nozzles made of plastic, similar to RAL colour RAL 9010 (-DW, white, standard), RAL 9005 (-DS, black), RAL 9006 (-DA, white aluminium) or RAL 9007 (-DG, grey aluminium).
