DUK- JET NOZZLE DIFFUSERS

Product catalog summary

Description: Jet nozzle diffusers are designed for applications where air needs to travel long distances from the discharge point to the occupied zone. They allow for adjustable discharge angles to suit heating or cooling modes, with a temperature difference range from -12 to +20 K. The DUK model features an adjustable throw angle and a special frame, while the DUK-M includes a motor for adjustment.

Material: Made from aluminum, these diffusers are known for their long throw distances and excellent acoustic properties. They are available in nominal sizes ranging from 100 to 400 mm and support volume flow rates from 15 to 400 l/s or 54 to 1440 m³/h.

Finishing: Standard finish is powder-coated in RAL9010, with other colors available upon request.

Installation: Options include screw mounting or no fixing. Accessories such as a plenum box are available.

Technical Data: The DUK selection table provides values for a discharge angle of 0°, with throw distances specified for isothermal operation.

Installation: The document includes a schematic illustration for installing the DUK-M model directly onto circular ducts, detailing components like the nozzle, face cover ring, actuator, casing, linkage, and spigot.

Order Codes: The order code system specifies options for neck diameter, actuator presence, mounting type, coating, and plenum box inclusion.
