Vulkan Energiewirtschaft Oderbrücke GmbH, based in Eisenhüttenstadt, pursues the goal of a secure and economical energy and media supply. Since its foundation in 1994, the company has acted as a regional service provider in the industrial and commercial centre of Eisenhüttenstadt.
As a long-standing customer of a German valve manufacturer, Vulkan Energiewirtschaft Oderbrücke GmbH benefits from its service team, which is regularly on site. This partnership ensures that the control valves in the power plant are maintained and guaranteed to operate smoothly. Recently, two injection coolers were successfully repaired. After 18 years in industrial use, the original performance parameters of the valves were restored through the overhaul.
Another focus was on converting the injection cooler actuators to ABB technology, in particular the ABB Contrac RHD250-10 quarter-turn actuator, which is characterised by being maintenance-free for up to ten years and enables continuous positioning, three-point or bus control. It is also stall-proof and requires no travel or torque-dependent switch-off. Mechanical stops limit the end positions and a handwheel allows emergency operation.
The accompanying microprocessor-controlled electronic unit with integrated frequency converter ensures precise control of the electric drives. This enables more precise control via the digital RS232 interface and improves the data documentation of the control sequences. Overall, this comprehensive solution promises to increase the efficiency of the injection coolers used at Vulkan Energiewirtschaft Oderbrücke GmbH.
