Ventilation Chimneys

Ventilation Chimneys

The formation of condensation and frost is a problem in all manhole structures. HUBER offers significant help in the form of a welded-on vapour hood on the manhole cover. Moist air is light, rises upwards in the shaft and is discharged at the highest point of the shaft through the welded-on vapour hood of the shaft cover. An additional ventilation chimney optimises this effect.
