Siemens expands damper actuator family

With the new 4 Nm-torque spring-return actuators, Building Technologies can more finely scale air damper motorization, thus avoiding unnecessary and expensive over-motorization. Spring-return actuators are primarily used when spring force is needed to move de-energized air dampers (e.g., power failure) into a defined fail-safe position.
The new conventional damper actuators with 2 Nm torque are now available for AC 230 V as well as AC/DC 24 V. This means greater flexibility and less effort during installation because no additional power supply needs to be installed, regardless of the controller's specifications. Other variants with DC 0/2-10 V control signals for continuously modulating actuators and for non-modulating actuators with 2/3- positions open up new control options for damper actuators.
The 2 Nm damper actuators are suitable not only for ventilation applications but also water applications, such as heated and chilled ceilings. There they contribute to a cost-efficient solution using the new DN10 6-way control ball valves from Siemens.
All the new damper actuators are equipped with a left-right switch that allows the direction of rotation to be changed without added cabling effort. With an IP54 protection class, the new models are highly resistant to dust and water and hence offer greater reliability during operation.
The modern air damper actuators of the OpenAir family are fast and easy to install thanks to the new one-screw shaft adapter. Other quality hallmarks include extreme robustness and long product life of approximately 100,000 full and 5,000,000 partial cycles.
Like all products in the OpenAir family, the new damper actuators have a printed data matrix code that allows instant online access to product information (datasheets, installation instructions etc.).
