Reliable Shut-off Dampers in Arctic Conditions

These shut-off dampers are designed to effectively close off the air intake when gas turbines are not in use.

In their open position, these dampers feature blades that align with the direction of the airflow, ensuring minimal pressure loss.

Furthermore, the supplied shut-off dampers are designed to withstand the most extreme arctic conditions. Their robust design allows them to operate flawlessly even in extreme cold, withstanding temperatures as low as -60°C. This exceptional resistance to cold makes them a reliable option for gas turbine applications in harsh arctic environments.

Specifications

Dampers are a practical choice when it comes to controlling and balancing airflow in high-pressure ductwork. These dampers are designed to meet international standards for both rectangular and round ducts, ensuring compatibility with various systems.

When the dampers are open, the blades are aligned with the direction of the airflow, allowing for smooth passage without causing significant pressure loss. This feature ensures efficient operation without compromising the overall performance of the system.

They are commonly used as shut-off, gas, and balancing dampers in applications where tightness and reliability are of utmost importance. With their dependable design, they provide a trustworthy solution for maintaining air tightness and achieving precise airflow control in diverse settings.

Material Thickness & Dimension

The shut-off, gas, and balancing dampers are designed to meet international standards, providing reliable performance in various applications. The dampers provided come in standard sizes for both rectangular ducts (with widths ranging from 100 mm to 1200 mm and heights from 100 mm to 1600 mm, in 1 mm increments) and circular ducts (with diameters from 100 mm to 1250 mm). Custom dimensions are also available upon request, ensuring a perfect fit for specific needs.

They feature a standard flange width of 27 mm, and flanges and drilling can be provided according to ISO 15138 standards. Additionally, for larger requirements, modular construction sizes are available up to 2400 mm by 3200 mm.

To ensure durability, the frame thickness of the dampers ranges from 3 mm to 10 mm, with the standard frame thickness being 3 mm. The blades of the dampers are crafted using a sandwich design, consisting of two sheets, each 1 mm thick. This construction enhances the structural integrity and performance of the dampers.

Overall, these dimensions and material specifications highlight the versatility and robustness of the dampers, making them a reliable choice for achieving tight shut-off, efficient gas control, and precise airflow balancing in various applications.
