#184 Hydraulic Turbine Compressor Oil
The extremely high viscosity index allows HTC to exhibit low temperature properties that permit hydraulic pumps to be safely started at low ambient temperatures where the flow properties of a conventional, straight grade hydraulic oil might cause problems.
HTC Oil is a premium quality multi-grade anti-wear non-detergent oil that is specially formulated for use in mobile and industrial pressure and high pressure hydraulic systems that are subjected to wide variations in ambient and system operating temperatures.
Includes VarniShield
Available in SAE 5W-30.
It is blended from the finest high viscosity index, solvent refined, severely hydro-finished, 100% pure paraffin base stocks available. Blended into these 100% pure paraffin base stocks is a highly specialized performance additive package and an extremely shear stable polymer-type viscosity index improver.
The highly specialized performance additive package provides HTC Oil SAE 5W-30 with the following performance benefits:
- Exceptional anti-wear protection.
- Extended pump life.
- Extended bearing life.
- Enhanced thermal and oxidative stability.
- Superior hydrolytic stability.
- Excellent demulsibility characteristics.
- Excellent rust and corrosion protection.
- Excellent anti-foaming properties.
- Reduced sludge, varnish and deposit formation.
- Improved durability of non-ferrous parts.
- Reduced filter blockage.
- Enhanced filterability.
- Enhanced compatibility with existing fluids.
- Enhanced fluid life.
- Enhanced seal life.
- Reduced system maintenance.
The extremely shear stable polymer-type viscosity improver provides HTC Oil SAE 5W-30 with a viscosity index of 140. This extremely high viscosity index allows it to exhibit low temperature properties that permit hydraulic pumps to be safely started at low ambient temperatures where the flow properties of a conventional, straight grade hydraulic oil might cause problems. Conversely, when the hydraulic equipment reaches operating temperature, the high viscosity index of HTC Oil SAE 5W-30 allows it to have the proper viscosity needed to minimize internal pump leakage and wear.
Trends in hydraulics
The trend among hydraulic pump builders and compressor manufacturer's is to employ higher speed and pressures. Further, many turbine systems, especially those that are geared type turbine systems are generally subjected to shock loads and occasional overloading. These conditions often result in conditions of thin film lubrication that can result in excessive wear. This excessive wear cannot only result in a loss in hydraulic pump, compressor and turbine efficiency, but also can result in a costly shutdown for maintenance.
Though HTC Oil SAE 5W-30 contains an exceptional anti-wear performance that last longer that most conventional anti-wear hydraulic fluids, even this exceptional anti-wear package also will disappear over time. To fortify its anti-wear capabilities, Micron Moly® is further blended into the oil.
The Schaeffer Solution
Micron Moly® is a liquid soluble type of moly that plates itself to the sliding, rolling and rubbing metal surfaces of the hydraulic, turbine and compressor systems. This plating action forms a long lasting solid lubricant film on these rubbing, rolling and sliding surfaces. This moly film will withstand pressures up to 500,000 pounds per square inch. Once plated to the sliding, rolling and rubbing metal surfaces the Micron Moly® not only produces a smooth finish surface, but also reduces friction between the moving parts. This results in less heat being generated, which in turn not only reduces operating temperatures, but also downtime.
HTC Oil SAE 5W-30 can also be used as an airline oil for pneumatic systems, as a circulating oil and in bearing applications, where a non-extreme pressure oil is called for. HTC Oil SAE 5W-30 meets and exceeds the following specifications and manufactures' requirements: Haggulands Denison HF-O, Vickers I-286-S and M-2950S, Rexnord, Commercial Shearing HD 21900, commercial Hydraulic, Cincinnati Milicron P-54 and P-68, DIN 51524 Part 1 & 2, US Steel 126, 127 and 136.
