The latest power industry contract for SIPOS Aktorik, the specialist supplier of variable speed electric actuator solutions, is at E.ON’s Franken 1 power plant in Nuremberg-Gebersdorf, Germany.
The project demonstrates the full scope of SIPOS expertise, which includes on-site support. Within the scope of the replacement of the 790 MW power plant’s control system, which will be managed by Siemens, SIPOS will install approx. 200 actuators / valves.
The company’s remit extends to delivery plus dismounting old and mounting new valves with actuators. SIPOS will collaborate closely with Siemens in the commissioning of complete units.
The application is significant for SIPOS as it confirms the company’s capability to provide a comprehensive partnership service. Commenting, Heinz Mueller, the Siemens Project Manager responsible for delivery of the new control system at Franken said: “We attach great importance to matching components and services from delivery through to commissioning and for the capability of one provider to offer a one source service. ”
Primary reasons cited by Siemens for the selection of SIPOS were the company’s partnership capabilities that extend beyond the supply of actuators. Additionally, SIPOS’ customer service credentials confirmed that the retrofit would be completed within a demanding time frame and led to the appointment of the actuator supplier.
A further advantage of SIPOS’ offer was the technology’s variable speed capability: SIPOS says that its actuators have a unique capability of slowing down before reaching their end position. Siemens said that this feature proved particularly attractive for this application as the solution extends the life of both the valve and its seat.
