Small Hydro Rehabilitation Projects

Sorensen Systems specializes in developing fluid power systems for small and micro hydro rehabilitation projects. We have decades of experiences providing cost-effective fluid power and electrical control systems as part of modernizing hydro installations. For instance, we design and manufacture of electro-hydraulic governors, gate-operating systems, and hydraulic lubrication and bearing cooling units.

Refurbishments & New Installations

Its in-house staff of engineers and design technicians have extensive experience with applications ranging from turbine speed control to water level management. System design, fabrication, installation, start-up and field maintenance are provided for:

  • High and low pressure electro-hydraulic conversion systems 
  • Remote gate positioning systems 
  • Ball valve, butterfly valve and fixed cone operating assemblies and systems
  • Turbine lubrication and cooling systems 
  • Crest, slide and roller gate control systems 
  • Gas/steam turbine combined cycle diverter systems 
  • Electro-hydraulic governor control systems
