The exhaust air chimneys offered by Big Dutchman are feature-rich, efficient, and productive. The CL600 & CL920 models are part of the CL series and have been running for the past 25 years.
These models are both suited for installation on the Roof, Side Wall or Gable, providing optimum performance with superior flexibility. Exhaust air volume can also be precisely controlled even in minimum ventilation conditions due to the motor-driven shutter.
Technical
- On site adjustments are easy as GRP is used to make the roof sheet and external ducts
- The CL 74 actuator can be used with the models to securely close the chimney and reduce the volume flow
- Ensures water tightness since there is a labyrinth seal installed between the roof duct and roof sheet
