Refining and Petrochemical Markets
Turbomachinery
Control Solutions, LLC has experience with control retrofits on numerous
types of steam turbines in refinery & petrochemical service. 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 are
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.
