Hi-Tec Bio-Hydraulic Oils S Type are biodegradable hydraulic lubricants containing synthetic fatty esters, stabilizers, anti-wear additives, corrosion inhibitors and foam inhibitors. They are biodegradable according to OECD 301B and meet the HEES requirements.
Hi-Tec Bio-Hydraulic Oils S Type do not contain mineral lubricating oils: they are based on high quality synthetic fatty esters derived from Australian harvested vegetable oils, which in comparison with mineral oil based lubricants, are more easily biodegraded, less hazardous and more suitable for use in environmentally sensitive areas. They are much less likely to cause any harm to soil, waterways or other parts of the environment than mineral oil based lubricants.
Hi-Tec Bio-Hydraulic Oils S Type display excellent viscosity – temperature characteristics due to the high naturally inherent viscosity indices of the vegetable oil based synthetic esters. They are specially formulated for high exposure or high temperature applications. The optimum operating temperature range is from -10oC to 100oC.
Compared with mineral oil based lubricants Hi-Tec Bio-Hydraulic Oils S Type are:

  • Safer for users and the environment
  • More easily biodegradable
  • Lower in toxicity – free from heavy metals
  • Enhanced in performance characteristics
  • Less changeable in viscosity as operating temperatures increase due to higher viscosity index
  • Higher in lubricity resulting in lower equipment operating temperatures

Hi-Tec Bio-Hydraulic Oils S Type were developed to meet and exceed the current requirements of the agricultural, forestry, heavy engineering, construction and marine equipment industries.
Hi-Tec Bio-Hydraulic Oils S Type can be used in mobile or stationary equipment such as forklifts, cranes, tractors, graders, bulldozers, hoists, marine equipment, mining equipment, ski lifts etc. and is particularly suited to use in environmentally sensitive areas such as;

  • National or State parks
  • Near or on waterways
  • Recreational areas
  • Road, rail and tramways
  • Local Government Maintenance Vehicles
  • Water, Electricity, Telecommunication and Gas Service providers etc.

Hi-Tec suggests that the equipment manufacturers’ recommendations for viscosity grade, performance requirements and general operating conditions should be checked prior to use.
Hi-Tec Bio-Hydraulic Oils S Type are fully miscible and compatible with mineral oils therefore changing to Hi-Tec Bio-Hydraulic Oils S Type is simple as no prior system flushing is required.
