Key Performance Benefits

HiTEC® 544 has been designed to provide superior performance over traditional hydraulic additive systems in severe duty and high-load applications. It increases the life of the hydraulic fluid whilst enabling operators to reduce the environmental impact of their operations.

HiTEC® 544 delivers performance benefits in a number of key areas:

  • Excellent oxidation stability
    • Capability to extend the oil drain interval resulting in reduced disposal costs. Potential to improve efficiency during the length of the oil drain due to decrease in deposits
  • Good sludge and particulate control
    • Improved protection of critical components with tight tolerances such as servo-valves and pumps
  • Exceptional wear protection
    • Delivering maximised equipment life and reduced maintenance costs
  • Excellent separation from water
    • Water contamination rapidly separated and maintained during service
  • Effective foam control in most base oil combinations
    • Additive package includes antifoam, precludes the need to purchase a separate foam inhibitor

Recommended Dosage

The standard treat rate for HiTEC® 544 is 0.82 % wt. It has been extensively tested in a range of Group I and II base stocks. HiTEC® 544 has demonstrated compatibility with calcium and zinc-containing hydraulic fluids. A small number of systems may require draining or flushing prior to first use. Please contact your Afton Chemical representative for specific recommendations.
