Control Solutions, LLC has experience with control retrofits on numerous
steam turbines in industrial manufacturing applications. We have
retrofitted the following types of turbines: Elliott, Worthington,
Dresser-Rand, GE, Westinghouse, DeLaval, Murray, Skinner, Coppus, Terry,
Mitsubishi, AEG, ABB, Allis-Chalmers, Siemens.
The following is a
list of typical steam turbine applications and control modes. The list is
not meant to be all-inclusive, but rather an overview of applications which
TurboControls can provide expertise and proven product solutions.
