Chimneys for exhaust systems

Cooling air chimneys

The cooling air chimney contains a ventilation and non-return flap as well as 2 measuring points which can either be optionally equipped with measuring instruments or used for own purposes. The chimney can be insulated on the outside. Depending on the operating conditions and use of the cooling air, which can also be used for heat recovery, it may be necessary to equip the system with an additional chimney cooling air fan to mix cold ambient air into the clean hot cooling air. Therefore, a connection of this optional system via the non-return flap is provided.

All chimneys are offered in a standard construction height of 6 m, with the possibility of an extension to 9 or 12 m. Other heights as special design.
