Frequently asked industrial damper questions (FAQ’s).

What is a damper?

An industrial damper is a mechanical device used in various industrial applications to control the flow of gas or air within a duct or pipeline. Essentially a fabricated valve, dampers are designed to regulate the flow rate, pressure, or temperature of the fluid in a system. They can be manually operated or automated, depending on the specific requirements of the industrial process. We have a full page dedicated to explaining exactly what a damper is, which you can read by clicking here.

What materials of construction are used for dampers?

The materials of construction will be determined by the process application, the operating environment and the project specifications. But we manufacture dampers in many different grades of steel including carbon steel, boiler plate, stainless steels (304, 316, 321, 310, 410), chrome moly, corten, duplex and high nickel alloys.

Can a damper be provided with insulation?

We routinely provide industrial dampers with internal insulation, usually in the form of either blanket / rockwool with stainless steel liners, or using a lightweight castable refractory. We can also design the damper to allow for external lagging at site, or with the external lagging pre-installed.

What types of damper actuators do DTL use?

We can provide dampers with a wide variety of actuation including manual lever, manual gearbox, electric, pneumatic, or electro-hydraulic. We also provide control additional instrumentation and controls for open / close operation, modulation operation, emergency shut down and failsafe operation.

Are DTL industrial dampers compliant with industry standards?

Whilst there is no overarching industry standard for the design of industrial dampers, we consider our designs, control our manufacture and provide certification according to many internationally recognised standards including:

Where are DTL dampers manufactured?

We can manufacture our dampers in UK, India, North America, Europe and China. So DTL are well placed to provide expert damper solutions worldwide.
