Heatex Damper
Heatex Damper


Suitable for close/open bypass exchanger section in connection with a cross-flow plate heat exchanger.

Product Information


The damper has hidden wheels for better protection against filth and mechanical damage. As standard, the driving shaft is placed on the end of the middle wing on the by-pass side, or by even number of wings the upper wing next to the middle. The damper can upon request be supplied with driving shaft turned inward.

As an option, the damper can be supplied painted which is standard for exchangers with a painted framework. We also recommend painted dampers for installation in areas with heavily polluted air.

A special only inside-bypass damper is also available.
