Siemens SQN31.111A2700 actuator

Siemens SQN31.111A2700 actuator: fast and reliable air damper control. Buying Siemens SQN31.111A2700 means equipping your burner with a high-speed electric actuator for precise air supply regulation. This model is designed for gas and oil burners of small and medium power and ensures an optimal fuel-air mixture ratio. Purpose and application: The Siemens SQN31.111A2700 actuator is intended for rotating air dampers of burner devices, controlling the precise ratio of fuel and air. It is integrated into single-stage, two-stage, or modulating burners of small and medium power. Main functions of the actuator: Damper positioning during ignition — supplying the amount of air necessary for safe ignition; Damper control during burner operation at low and high power; Opening the damper during combustion chamber purge to remove residual gases. The actuator is controlled by burner controls (combustion managers) LOA..., LMO..., LMG..., LFL..., and is also compatible with P-PI or PID controllers, e.g., RWF40.
