Série DUK

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
