DIVERTER DAMPER
High-Temperature 3-Way & Bypass Gas Diverting System
The Diverter Damper is an engineered heavy-duty gas diversion system designed with one inlet and two outlets using a single pivot blade mechanism for rapid modulation (under 30 seconds) between the main stack and HRSG bypass. Built with up to 99.9% sealing efficiency (using Seal Air systems) and capable of continuous operation up to 1000°C.

Complementary Damper Solutions
COFFEEPOT DAMPER
The Coffee Pot Damper is a strong and reliable safety damper used in HAG and attached on hot-air ducting systems. It is designed to handle high temperature and pressure conditions. The damper can be operated by a pneumatic cylinder or electric actuator, while the counterweight arrangement helps in quick opening during emergency situations. Its simple, robust design makes it suitable for safe industrial operation.
MULTILOUVER DAMPER
The Multilouver Dampers are used for airflow regulation and isolation in ventilation, fans and industrial air-handling systems. The damper has multiple adjustable louvers mounted in a strong fabricated frame, which helps in smooth and uniform air control with low pressure drop. Louvers are connected through an external linkage for easy and synchronized operation. The damper can be provided with manual or motorized operation and customized in size, material and arrangement as per application requirements.
GUILLOTINE DAMPER
The Guillotine Damper is a heavy-duty damper designed for reliable ON-OFF isolation of air, gas and process ducting systems. It is available in Round and can be manufactured as per required duct/flange dimensions. The damper is suitable for high-temperature and industrial applications where low pressure drop, easy inspection and maintenance are required. When fully open, the passage remains clear, resulting in minimum load loss.
