DESCRIPTION:
Hybrid chimney cowls
Work like ordinary wind turbines when wind conditions are sufficient, when not, electric motor speeds the cowl up to the rotating speed set.
DESCRIPTION:
Hybrid Turbowent chimney cowls are devices, which, in a dynamic way, use force of the wind to increase chimney draught. They are also 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.
Its construction allows it to be mounted on ducts which are very close to each other.
Maximum ventilation efficiency at minimum exploitation costs
