Gas-Tight Shut-Off Dampers
Shut-off dampers are implemented to allow or block airflow within HVAC systems on ships, maritime vessels as well as carbon capture applications.
Four pieces are welded together to construct a heavy-duty frame. This allows the damper to be applied on load-bearing constructions including bulkheads, bridges, or onto the sides of vessels.
The steel used to make the dampers is galvanized, painted, or stainless steel. Blades contain stainless steel spring seals or silicon seals. A variety of accessories, as well as an pneumatic, electrical, or manual operation system, are available.
By understanding their features and the benefits they offer, we can truly appreciate their real-world value and the positive impact they have on advancing Carbon Capture and Sequestration (CCS).

Dampers used in Carbon Capture
Dampers play a crucial role in ensuring the efficient and effective capture of carbon dioxide (CO2) emissions.
The following are the key characteristics of an ideal damper for carbon capture and optimization to mitigate climate change:
- Gas-Tight Seal: An ideal damper for carbon capture should possess a gas-tight seal. This feature ensures that once the CO2 is captured, it remains securely contained, preventing any leakage back into the atmosphere. By maintaining a reliable seal, the damper helps maximize the efficiency and integrity of the carbon capture system.
- High Flow Capacity: Carbon capture involves handling significant volumes of gas. Hence, an ideal damper should have a high flow capacity, allowing for the smooth and uninterrupted movement of gases. With this capability, the damper can effectively manage the large-scale capture of CO2 emissions from industrial sources.
- Temperature Resistance: Carbon capture processes often take place in high-temperature environments, such as power plants or industrial facilities. An ideal damper should be designed to withstand and operate reliably under these extreme conditions. With temperature resistance, the damper can effectively handle the hot gases encountered during the carbon capture process.
- Quick and Responsive Actuation: In carbon capture systems, quick and responsive actuation of the damper is crucial for optimal control over gas flows. The ability to actuate swiftly and responsively allows for timely adjustments to changing process conditions. This feature ensures efficient capture of CO2 by adapting to fluctuations in gas composition, pressure, or temperature.
- Robust Construction: Durability is a key aspect of an ideal damper for carbon capture. It should be built with sturdy materials capable of withstanding the harsh conditions and demands of carbon capture processes. A robust construction ensures that the damper can operate reliably over an extended period, contributing to the long-term effectiveness of the carbon capture system.
By incorporating these key features into the design of dampers for carbon capture, we can enhance the efficiency and reliability of the entire process.
Investing in the development and implementation of such ideal dampers brings us one step closer to achieving our goals of combating climate change through effective carbon capture.
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.
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.
