Dampers from Damper Technology Limited.

DTL Butterfly dampers provide a simple and cost effective method of control and isolation. Stainless steel dampers for high temperature applications are available in a variety of sizes. Various sealing arrangements can be used to provide the correct efficiency for your application.

Sealing efficiency can be increased to 100% with the addition of twin seals and a sealing air fan. Butterfly dampers can be actuated pneumatically, electrically or manually by a simple hand lever or reduction gearbox.

DTL Guillotine Damper and blanking plates can be used in any application where a positive isolation is required for routine maintenance and/or entry to a duct behind a media source.

Our guillotine designs have a record of proven reliability on major UK and overseas power stations as well as offshore installations. Actuation can be manual, pneumatic, hydraulic or electric, with various designs to suit all budgets and specifications.

Vane Damper is predominantly used on fan inlet applications, offering an enhanced level of flow and pressure control. A Radial Vane Damper has multiple blades arranged around a central hub enhancing the performance of the fan by introducing swirl into the fan inlet providing an efficient method of control. DTL’s Radial Vane Dampers can be fitted with any form of actuation allowing either local or remote modulating control. Engineered to ensure ease of maintenance and service without removing the damper from the fan and designed to withstand the high air velocities that can be experienced in use.

To minimise heat loss from the boiler and to prevent the ingress of rain water, Damper Technology Ltd have a range of stack isolating dampers which are designed for use with stacks from 300mm dia to in excess of 7m diameter. The stack isolating damper can be of the butterfly, twin louvre, multilouvre or twin flap design and can incorporate an automatic pressure relieving system to prevent over pressurisation and damage to the turbine.
