Stack Damper
To minimize heat loss from the boiler and to prevent the ingress of rainwater, we offer a range of stack isolating dampers which are designed for use with stacks from 300mm diameter to in excess of 7m diameter.
The stack isolating damper can be either a butterfly, multilouvre or twin flap design and can incorporate an automatic pressure relieving system to prevent over pressurization and damage to the gas turbine.
