Long Throw Nozzle WDA

Long throw nozzle WDA

Specification text

Long throw nozzle for air-conditioning of large and high rooms, such as halls, theatres or concert halls. The cone-shaped body of the nozzle increases air velocity ensuring a stable core jet. This results in very long throws. The dynamic internal construction of the jet nozzle allows a very high exit velocity at low noise levels and high induction. The technical data is secured and guaranteed by measurements and documentation in Schako's own fluid dynamics and acoustics laboratory. Suitable for cooling and heating modes. A wide range of connection and installation options such as wall, ceiling, duct or pipes. Consists of the nozzle part made of aluminium painted with a high-quality powder coating to a RAL colour (RAL 9010, white, standard). Suitable for use in VAV systems.

Accessories:

-Swivel head (-SK) for adjusting air outlet direction, without any change in the pressure loss or noise level, consisting of:

-Aluminium painted with a high-quality powder coating to the RAL colour of the nozzle (standard RAL 9010, white)

(not possible for NW 050)

-Swirl disc (-DS) consisting of sheet steel painted with a high-quality powder coating to RAL 9005 (black) which increases induction, reducing length of throw and end velocities of jet

-Reduction piece (-RS) for connecting small pipe diameters, made of sheet steel painted with a high-quality powder coating to the colour of the nozzle

(only WDA-F/W-... NW 063 - 200 possible).

-Electric actuator

(only available with swivel head NW 063 - 400):

-Actuator mounted externally on the left (-AL, standard)

-Actuator mounted externally on the right (-AR)

-Actuator mounted internally (-AI, at an extra charge)

(not possible for NW 400)

-(230 V AC, 3-point activation)

-(24 V AC, 0 - 10V; standard model)

-(24 V AC, 3-point activation)

-Cover plate (-BR) for covering the fixing and fastening screws, made of sheet steel painted with a high-quality powder coating in the same color as the nozzle (only NW 063-200 available)

-Damper (-DV), for manual volumetric flow adjustment, made of galvanised sheet steel (only NW 400)

-Ball impact guard, made of steel painted with a high-quality powder coating to RAL 9010 (white) (NW 063-200 only) (not for models -W and -R)
