Steel mill roll mill stand and Morgoil lube reservoirs are commonly plagued with high water ingression from leaky back-up bearings leading to high oil consumption and premature fluid replacement due to degradation from high water and particulate contamination. Decanting a mixture of free water and oil from the bottom of lube reservoirs is all in a typical day at many steel mills. The other problem with high water levels in lube oil is the loss of lubricating properties leading to bearing failures that can cost up to $30,000 each excluding downtime. Hy-Pro Vac-U-Dry vacuum dehydrators rapidly remove free and dissolved water to < 30ppm combining heat, vacuum and intuitive design for ease of operation. VUD skids include high efficiency on-board particulate removal filters to achieve more suitable ISO Fluid Cleanliness Codes yielding Longer Bearing and Fluid Life. Vac-U-Dry is optimized to perform on lube oil viscosities up to and above 680 cTs.
Combustion turbines (CTs) utilize lubricating and hydraulic control fluids for a wide range of applications. CTs with combined lube and hydraulic control reservoirs (GE Frame 6/7) are susceptible to varnish deposit formation which leads to unit trip and fail-to-start conditions (servo valve stiction) especially in the growing population of peaking gas turbines. Group I lube oils have given way to Group II base stock oils which have lower solubility characteristics. Lower solubility means that the newer Group II lube oils cannot hold the same levels of soluble (dissolved) or insoluble (suspended) oxidation and thermal degradation by-products in the oil thus leading to more problems with sediment, sludge and deposits (varnish). Hy-Pro has the solution to make varnish vanish . . . The SVR (Soluble Varnish Removal) removes oxidation by-products while still in solution (dissolved) to remove varnish deposits that have formed over time and to prevent varnish from ever forming. Stop varnish before it stops you with SVR!

Break the drain and refill gearbox oil change cycle and improve reliability, extend useful oil life and avoid premature contamination gearbox rebuilds by installing Hy-Pro FSL dedicated off-line filter skids specifically designed for high viscosity lube oils. High flow LF housings are also a good fit for adding high efficiency filtration to existing re-circulation lines on coal mils to control particles and water contamination.
Steam turbine EHC systems typically utilize fire resistant phosphate ester fluids which can present certain contamination challenges resulting in servo valve failure or premature fluid replacement. However, when properly maintained phosphate ester fluids not only provide the safety of fire resistance and years of reliable EHC system operation free of contamination related servo valve failures and indefinite fluid life. Hy-Pro has the full solution for phosphate ester to properly manage and eliminate problems with acid production, water contamination, dissolved metals, sub-micron products of thermal degradation, dark fluid, sludge and deposits and particulate contamination.
Hy-Pro DFE rated elements yield cleaner fluid in EHC systems in pump discharge and servo pilot filters. Prevent servo valve failures caused by contamination related failure. Hy-Pro Dynafuzz element upgrades feature stainless steel fiber media that is impervious to the effects that acid formed in phosphate ester can have on some glass medias. DFE rated Non-SparkingDynafuzz elements provide superior fluid cleanliness and solve the media migration issue in phosphate ester EHC fluid.
Dedicated filtration and breathers on bulk storage tanks for lube and hydraulic oils and stand-by diesel fuels is the first line of defense in preventing one of the worst sources of particulate and water contamination, new fluids. Bulk storage tanks collect contaminants from delivery vehicles and through ineffective breather arrangements. Eliminate this dangerous source of contamination and before transferring new fluids into critical power plant operating systems. Filter Carts are also a valuable tool for keeping fluids clean when transferred from storage to critical live systems.
Large compressors typically utilize the same turbine oils used in the turbine lube reservoirs and are susceptible to many forms of contamination including varnish, particulate contamination and water contamination. Hy-Pro has a suite of solutions available to improve compressor reliability including DFE rated element upgrades, Water Removal Elements, varnish mitigation and acid removal.
Hy-Pro has a full complement of solutions for lube & hydraulic contamination challenges in power generation. For more information on turbine related products and strategies please select the turbine type to visit the industry applications for combustion or steam turbines
DFE rated filter element upgrades ensure reliable fan operation and low ISO Codes. Dedicated off-line Filter Panels and skids are also suitable where fans are not fitted with sufficient contamination control. The V1 Portable Mini-Vacuum Dehydrator is ideal for solving periodic or continuous water issues on FD and ID fan reservoirs.
Many BFP or Seal Oil systems utilize antiquated filtration (i.e. Auto-Kleen) with coarse wire mesh filtration leaving ISO Codes excessively high for optimum reliability. Upgrade elements to Hy-Pro DFE rated elements, and housings to Hy-Pro DFNseries duplex filter assemblies or MF3 simplex housings featuring DFErated high efficiency glass media elements for years of reliable performance.
