Varnish Prevention & Removal

Varnish contamination is a by-product of many degradation processes in hydraulic and lubrication systems. The effects of varnish on industrial and manufacturing systems range from the nuisance of minor downtime and routine maintenance to catastrophic failures of major capital equipment.

Hy-Pro advanced media technologies provide a holistic approach to solve lube oil varnish to prevent premature equipment & servo valve failure, extend useful fluid life and provide reliability of in-service fluids and systems.

Condition AW Hydraulic Oils with Sludge & Varnish Problems.

Hy-Pro have a complete recovery & maintenance solution for mineral oil based turbine oils & lubricants. ICB Ion Charge Bonding filter elements significantly reduce production losses and resolve servo valve issues by eliminating the contaminants responsible for sticking or sluggish valves.

FSLVAW for AW Hydraulic Oils with Sludge & Varnish.

Condition AW Hydraulic Oils with Sludge & Varnish Problems.

• High efficiency particulate removal (< 0.7m), water & insoluble sludge & varnish removal.
• Ideal for AW type hydraulic fluids where sludge build-up is causing valve stiction.
• Prevent premature oil replacement and extend useful oil life.
• Ideal for in plastic injection molding, steel mill and other hydraulic control applications.

FSTO Turbine Lube Oil Varnish Removal

Ideal for Maintenance of Small Turbine Lube Oil & Compressor Reservoirs

• Prevent varnish related servo valve failures on small gas turbines and compressor lube oil applications (ie gas transmission compressor units).
• Remove & prevent varnish deposits with ICB element technology (Ion Charge Bonding).
• Achieve & maintain MPC value < 20 (lower varnish potential).
• Lower ISO codes to 14/12/9 with high efficiency post filter element.
• Extend life of anti-oxidant additives & prevent premature oil replacement.

 

 

Non Spark Discharge Filter Element Upgrades

Filter element spark discharge is a recognized cause of fluid degradation in hydraulic and lube oil systems creating soluble by-products and sub-micron carbon particles that deplete additives, cause fluid darkening and lead to varnish deposits. Oil formulation changes from Group I base stocks to Group II-III base stock oils has yielded fluids with reduced conductivity characteristics which enhance the effects of element sparking especially during cold start conditions. Hy-Pro NSD (Non Spark Discharge) elements prevent one of the primary causes of thermal fluid degradation and is an important part of varnish deposit formation and phosphate ester fluid maintenance.

OA-TO Turbine Oil Analysis

Two levels of analysis; MPC only for trending varnish potential monthly & a deeper analysis for periodic monitoring.

• MPC (membrane patch Colourimetry)
• MPC patch weight (mg)
• RULER (remaining anti-oxidant level)
• ICP spectrometric element analysis ppm
• Water Content by KF (ppm)
• ISO4406:1999 particle count (4/6/14)
• AN (acid number)
