As a result, the public utility, Stadtwerke Heidelberg replaced approximately 50 pneumatic devices with AUMA SGC electric actuators. Leakage in the compressed air system was recognised as representing an additional, and considerable, cost for the pneumatic actuators. AUMA’s electric actuators are powered by maintenance-free electrical cables, ensuring high energy efficiency: calculations determined that savings during operation justified procurement of the electric actuation technology.
The SGC actuators’ highly compact design 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.
