DUK

• Jet nozzles as supply air diffusers, with a long throw distance
• For factories, 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 – +20 K
• Adjustable discharge angle from -30 – +30°, for switching between heating and cooling mode
• Connection options:
• Push-fit connection onto circular air ducts (pipe connection)
• As a direct branch from circular and rectangular air ducts
• For installation in walls or bulkheads
  
  

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

Nominal sizes
