Sludge and Varnish deposition in Turbine Oil and Hydraulic Control Oil system, caused Turbine trips, Servo valves failures, Sticking valves, high bearing temperatures, filter choking, restart problems and poor oil cooler efficiency.

HYPRO SVR1200 Soluble Varnish and contamination removal unit was selected for turbine Oil and System cleaning in order to eliminate the associated problems. To quantify the results, bi-monthly Oil analysis was conducted to monitor the improvement in oil condition. Within 3 months of installation of HYPRO SVR1200 unit, the results were achieved. Eliminated turbine trip events related to sticky valves, Improvement in bearing temperatures, reduction of filter consumption due to reduced filter choking, oil cooler efficiency improved.
