Notes
Product Overview
The Siemens SQN75 is a high-torque damper actuator designed for medium to large industrial burner systems.
As part of the SQN70 series, it provides reliable air damper positioning control to ensure precise air-fuel ratio regulation in combustion processes.
The SQN75 is commonly used in industrial boilers, furnaces, kilns, and process heating systems where stable and accurate combustion control is required.
Its increased torque output makes it suitable for larger air dampers and more demanding industrial environments.
This actuator integrates seamlessly with burner management systems and supports staged or fully modulating burner operation depending on system configuration.
