Since the past 7 years, our organization has been renowned appreciation as the topmost manufacturer, exporter and supplier of Industrial Dampers like Electrically Operated Dampers, Square Louver Damper, Bypass Damper, High Temperature Damper and others. Extensively used in commercial and industrial sectors, the offered industrial dampers acts as a valve to regulate the air-flow within the installed spaces. The provided damper is manufactured by our adroit professionals using utmost quality components and contemporary techniques in line with international quality standards. Available in different designs and technical specifications, these Industrial Dampers is offered to the clients at reasonable prices.
Damper Performance
Design Characteristics
Material Selection:
The material selection is characterized as per the operational conditions to which the industrial dampers will be exposed. This helps to ensure the best equipment performance. Gases from carbon combustion & fuel-oil, from cement factories, with sulphur, metal oxide, chloride etc. may reason early wear and troubles with corrosion, which should be analyzed in all cases.
Sealing Efficiency:
Closing degree of Industrial Damper is measured as an equivalent open area percentage. In other terms, an industrial damper with closing degree of 99% is equivalent to have 1% of the conduit area open. In reality, the flow leakage percentage is from 3 to 6 times said area, hence a damper with 99% closing degree will permit leakage of from 3% to 6% of the gas flow.
Damper
Industrial Damper can be regulation type or on/off type to which a position transmitter signal or positioner may be added for the purpose of automation.
Damper Types
Wheel & Gearbox: Manual system is appropriate for units that do not have a high automation level, and with small sized dampers.
Pneumatic: With 1⁄4 turn cylinder or linear; rendering very fast actuation. Involves a 5 to 7 bar air-pressure line. An air tank may be enclosed for emergency override.
Electric: Multi-turn electric motor or 1⁄4 turn electric motor, with gear box; supplied with a manual wheel for emergency override.
