chimney elements: chimney roots
ROTOWENT on plain bearings
The self-adjusting chimney cowl ROTOWENT (on slide bearings) is a device dynamically using wind power to support chimney draft. Regardless of the direction, strength and type of wind, the outlet of the root cap is positioned on the leeward side of the wind blowing. It is mounted on ventilation chimneys with gravity, combustion and smoke.
application:
– for supporting gravitational exhaust ventilation and draft in the flue and smoke chimneys
– when there are air turbulences at the outlet of the chimney caused by its unfavorable location
– with unfavorable terrain configuration, strong and frequent winds (II and III wind load zone)
– when there is no stabilized chimney draft or it is too small
Warranty: 2 years
– Maximum working temperature – 500 [° C]
– Rotating system: plain bearings
