HTC Oil with VarniShield® ISO 32

1 of 8 products in this brand
HTC Oil with VarniShield® ISO 32 is a premium quality non-detergent, anti-wear, rust and oxidation inhibited oil that is specially formulated for use in those critical high precision industrial and mobile type low pressure and high pressure hydraulic systems, rotary vane, rotary screw, reciprocating, axial and centrifugal type air compressor systems and vacuum pumps and blower applications. HTC Oil is particularly suited for those hydraulic applications such as plastic injection molding machines, glass transfer systems, heavy presses, numerically controlled machine tools and mobile equipment where excessive operating temperatures are seen and protection against the formation of varnish deposits on close clearance servo-valves and other system components is critical.

Features & Benefits

Benefits

HTC Oil is formulated from the finest high viscosity index severely solvent refined, severely hydrofinished base stocks available which provide the following benefits:

  • Excellent thermal stability.
  • Excellent resistance to oxidation and thermal degradation.
  • A naturally high viscosity index which provides a minimum change in viscosity that helps preventexcessive leakage, sluggish operation, lower overall efficiency and other deficiencies attributed to low viscosity index oils over wide operating temperature ranges.
  • Excellent film strength for increased wear protection.
  • Excellent operating temperature reduction. 100% base oils have better specific heat values, (less heat is absorbed) and better thermal conductivity that conventional base oils. These combined properties help reduce operating temperatures.
  • Superior chemical stability.
  • Low volatility wich allows lower makeup requirements from evaporation loss and fewer deposits.
  • Low carbon forming tendencies.
  • Compatible with all types of seals and coatings.
Product Highlights

VarniShield™ is patented hydraulic fluid additive technology designed to prevent the formation and buildup of varnish deposits, while providing exceptional anti-wear performance, outstanding thermal and oxidation stability, rust and corrosion protection and rapid water separation. The VarniShield™ additive system provides HTC Oil with a high degree of thermal and oxidative stability thus minimizing the formation of sludge and varnish. If any varnish particles do form, the dispersancy of the VarniShield™ additive will keep these particles suspended to prevent them from depositing on critical internal components. This helps eliminate the replacement of components such as filters and valves and the costs associated with these activities. In addition to protecting against the formation of varnish deposits and keeping the system clean and operating longer, the VarnishShield™ additive technology provides the following performance benefits:

  • Exceptional and long lasting anti-wear protection to protect system components
  • Extended pump life and bearing life.
  • Enhanced thermal and oxidative stability.
  • Superior hydrolytic stability.
  • Excellent demulsibility characteristics so water separates quickly.
  • Excellent rust and corrosion protection that extends component life and protects multi-metallurgy components.
  • Excellent anti-foaming and air release properties.
  • Reduced sludge, varnish and deposit formation.
  • Improved durability of non-ferrous parts.
  • Reduced filter blockage and excellent filterability.
  • Enhanced compatibility with existing fluids.
  • Excellent fluid quality reserve to maintain its performance features even under severe service conditions and extended drain intervals.
  • Enhanced fluid and seal life which provides reduced system maintenance.

The trend by hydraulic pump manufacturers to employ higher speeds, higher pressures, reduced cycling times and smaller systems along with the fact that in many applications the equipment may be operating beyond its design capacity can result in thin film lubrication conditions. These thin film lubrication conditions can result in increased wear conditions and rates, which can lead to a loss in system efficiency, reduced equipment life and potentially catastrophic system failure.

HTC Oil also contains Micron Moly®, a liquid soluble type of moly that plates itself to sliding, rolling and rubbing metal surfaces of hydraulic and compressor systems. This plating action forms a long lasting solid lubricant film on surfaces that will withstand pressures up to 500,000 pounds per square inch. Micron Moly® not only produces a smooth finish surface, but also reduces friction between the moving parts which results in less heat being generated, lower operating temperatures, and a reduction in downtime.

Uses

HTC Oil can also be used as a slide and way lube, an airline oil for pneumatic systems, as a circulating oil and in those bearing and gearbox applications, where the use of a non-extreme pressure oil is specified.
