Type DUK

For installation into walls and onto rectangular and circular ducts, adjustable and fixed – made of aluminium

Adjustable and fixed jet nozzles achieve long throw distances and have excellent acoustic properties

  • Nominal sizes: 100, 125, 160, 200, 250, 315 and 400 mm
  • Volume flow rate range: 15 to 400 l/s or 54 to 1440 m³/h
  • Visible parts made of aluminium
  • For variable and constant volume flows
  • Low sound power levels due to aerodynamically optimised nozzle contours
  • Discharge angle can be adjusted manually or with an actuator
  • Quick and easy to fix, concealed fixing


Optional equipment and accessories

  • Exposed surface in RAL CLASSIC colours
  • Circular spigot
  • Connection pieces for circular and rectangular ducts
  • Internal or external actuators for adjusting the discharge angle

Jet nozzles type DUK suitable for long throw distances with optimum acoustic properties, preferably used for heating and cooling in critical areas. The adjustment facility – manual or automatic via internal or externally mounted electric actuation – allows variation in discharge angle to compensate for changing temperature differences, adjustment angular range 30° upwards to 30° downwards. The manually adjustable version can also be rotated through 360°.The fixed jet nozzle type DUK-F consists of an aerodynamically shaped discharge nozzle deep-drawn in one piece, with fixing holes. Adjustable construction type DUK-V consists of a discharge nozzle with spherical outlet mounted in a housing, a mounting flange and in a circular duct rear connection spigot for direct connection to a circular duct. Also available with rear-mounted duct connecting element with peripheral flange and optional spigot or saddle connection with flange for fixing to the side of rectangular or circular ducts; the rear contour of the saddle connection is profiled to the duct diameter.

MATERIALS AND SURFACES
- The discharge nozzle and face cover ring are in aluminium, the mounting for the eyeball is with two plastic rings colour white RAL 9010 (Temperature resistant up to max. 50 °C), the connection element and saddle connection are in galvanised sheet steel. The surface can be pre-treated and powder coated in white (RAL 9010) or another RAL colour (the spigots remain galvanised finish).

Application

Application

  • Type DUK jet nozzles for supply air discharge, with a long throw distance
  • For production halls, gymnasiums, theatres and conference rooms as well as for large internal spaces in airports, railway stations and shopping centres
  • Attractive design element for building owners and architects with demanding aesthetic requirements
  • For supply air to room air temperature differences from –12 to +20 K
  • Adjustable discharge angle, from –30 to +30°, for switching between heating and cooling mode
  • For push fitting directly onto circular ducts or as a branch off circular or rectangular ducts; also for installation into walls and bulkheads

Special characteristics

  • High discharge momentum, hence large penetration depth in heating mode
  • Optimised nozzle contours
  • Fixed and adjustable variants
  • Discharge angle can be adjusted from –30° to +30°, either manually or with an actuator
  • Electric actuator as an option

Nominal sizes

  • 100, 125, 160, 200, 250, 315, 400 mm
