Electric actuators replace pneumatic technology

01 July 2014

Compact electric actuators have offered energy cost savings for a water treatment plant, compared to the previously used pneumatic technology.

The high maintenance costs of pneumatic actuation technology for valve control, with its associated compressed air supply, were reviewed as part of a modernisation initiative at the Schmidtsche Quelle water treatment plant in Heidelberg, Germany. As a result, the public utility, Stadtwerke Heidelberg replaced approximately 50 pneumatic devices electric actuators supplied by Auma.

Leakage in the compressed air system was recognised as representing an additional cost for the pneumatic actuators. In contrast, AUMA’s SGC range of electric actuators are powered by maintenance-free electrical cables which ensures high energy efficiency. Calculations determined that savings during operation justified procurement of the electric actuation technology.

The compact design of the actuator met the scheme’s prerequisites, as installations were required in cramped locations. Additionally, availability of a Profibus DP interface enabled actuator integration into the new control system.
