Siemens SQN30 Burner Actuator
SQN30.111A2700
Servo actuator for air damper control in burner systems.
The Siemens SQN30 electromotoric actuators are precisely engineered for driving air dampers on small to medium-capacity gas or oil burners. Working in conjunction with burner control units (e.g., LFL, LME series), they modulate the air volume during pre-purge, high-fire, and low-fire operational sequences. Featuring integrated mechanical limit switches and a position indicator, they allow streamlined calibration during onsite commissioning.
