SIE-M • Non-Spring return actuators

  • Actuators
  • Without spring return

  • Durable actuators for HVAC applications, air volume control as well as fire and smoke protection dampers

  • The damper actuators provide optimum ventilation in a particularly energy-efficient manner because their low-consumption motors deliver high positioning forces using little energy. The actuators for air volume control also save energy thanks to their highly precise measured value acquisition, which prevents energy losses

  • In addition to energy savings, the damper actuators also pay off due to their long service life: Thanks to a very robust housing, they are resistant to the rough conditions encountered during transportation, storage and on the construction site. Moreover, a functionally tested module concept ensures maximum quality and reliability


Application

  • Actuators for HVAC applications are available for low and high torques, so you can choose the right product for any type of application. The powerful actuators with 35 Nm offer maximum safety under demanding operating conditions. And with their compact design, the small actuators with 2 Nm are ideally suited for difficult installation conditions. They can also be easily mounted in tight places, e.g. in false floors. Fast-running damper actuators with a torque of 6 Nm and 2 s running time are perfectly suited for special applications like fume hoods
  • Self-centering shaft adapters simplify installation and reduce installation expenses – and make mounting foolproof. They also reduce the stress on the actuator, which increases its service life and reliability

Specifications

  • High reliability thanks to high torque
  • Compact actuators for difficult installation conditions
  • The suitable actuator for every application – e.g. fastrunning damper actuators for laboratories
  • Simple installation thanks to self-centering shaft adapters
