Chimneys ensuring optimum air extraction

The exhaust air chimneys offered by Big Dutchman are feature-rich, efficient, and productive. The CL600 & CL820 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

Advantages of CL 600 & CL 820

  • Enhances fan performance and reduces power consumption with their optimised integrations
  • Provide efficient air extraction, thanks to their aerodynamic design
  • Highly durable as they are insensitive to sunlight and frost
  • Easy to assemble, clean, and dismantle
  • Don’t need any additional sealing material
  • Have a self-supporting design, thus there’s no need for supplementary suspension or bracing
