Darco system


It guarantees stable ventilation at minimal costs.

Hybrid Turbowent chimney cowl NET version is a device, which, in a dynamic way, use force of the wind to increase chimney draught. It is equipped with a low power brushless electric motor. When the wind speed is too small to achieve the desired efficiency, electric motor speeds the turbine up, when it is too strong it slows the turbine down. When the wind speed is strong enough to achieve the rotation speed set on the steering device, motor does not work, and cowl works just like the ordinary Turbowent.

Network version – NET is equipped with a logic module placed in the control box of the base. This module allows to integrate cowls into a network and control them by using special Darco PC computer programme. Network version is compatible with inteligent building systems based on the protocole of data transmission Verso-Bus type.


  • creating hybrid ventilation systems
  • when there are wind fluctuations on the chimney duct ending, caused by its bad location
  • when there is an unfavorable terrain configuration, with strong and frequent winds
  • when there is a lack of chimney draught or it is too weak
  • in order to improve the natural (gravitation) ventilation
