Lube Oil Water Removal by Vacuum Dehydration.
  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 optim

ized to perform on lube oil viscosities up to and above 680 cTs.

Gearbox Filtration.  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.

Bulk Fluid Handling. 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.

Compressors. 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.
