Actuators for Building Management Systems
Zone control for Building Management Systems requires accurate, reliable and low-noise actuators with a long lifetime expectation and equipped with many control options. Möhlenhoff´s thermal and motoric actuators fulfil these requirements to our customer´s satisfaction as they are exactly designed for this purpose.
Actuators for Building Management Systems
Automatic zero-point and valve stroke calibration provide an accurate true control signal even if not every valve stroke is identical due to its production tolerances. Noiseless thermal actuator technology with any control signal provides appropriate solutions with forces up to 125 N. For higher forces of up to 200 N the low-noise motoric actuators fulfil these requirements in a similar way. Whereas thermal actuators are intrinsically fail-safe, motoric actuators are also available in special fail-safe versions using a powerpack concept enabling the actuator to run to any preconfigured position when power is interrupted.
Our full range of zone control actuators are topped off with a Modbus interface enabling full integration into Building Management Systems.
