Modernization of existing hydraulic systems and turbine controls

Retrofit Solutions

Extend the lifespan of your technology – economically and reliably

With decades of experience in energy and plant engineering, Keicher Engineering AG offers specialized retrofit solutions for hydraulic systems. Whether it’s outdated units, hard-to-replace control blocks, or obsolete valve technology: We modernize strategically and tailored to your existing infrastructure – mechanically, electrically, and in terms of control technology.

Typical Retrofit Areas

In the modernization of hydraulic systems, the focus is on replacing outdated technology with current, standard-compliant solutions. Our retrofit projects include both mechanical components like units and accumulators, as well as electronic controls – always aligned with the existing infrastructure.

  • Replacement of outdated hydraulic units (e.g. with silenced units)
  • Retrofitting existing control blocks to modern screw-in technology
  • Replacement of old proportional valves and pressure control stages
  • Integration of digital sensors and measurement systems
  • Migration from analog controls to PLC or fieldbus
  • Retrofit of quick-closing, safety, or bypass functions
