HAROL HY Series Zinc-Free Hydraulic Oil is engineered for hydraulic systems that require high-performance lubrication without the use of zinc-based additives. Its advanced ashless additive technology provides effective wear protection while minimizing the risk of deposit formation and environmental impact.

This hydraulic oil offers excellent thermal and oxidative stability, helping maintain consistent viscosity and performance over extended operating periods. It resists breakdown under high temperatures and pressures, reducing sludge formation and helping keep systems clean.

HAROL HY Series also demonstrates strong demulsibility, allowing it to separate efficiently from water and maintain lubrication performance in environments where moisture contamination may occur. Its anti-foam characteristics ensure smooth system operation by preventing air entrainment and cavitation, improving efficiency and reliability.

This Zinc-Free Hydraulic Oil is particularly well suited for systems containing silver-plated components or sensitive materials where traditional zinc-based oils may cause compatibility issues. It is suitable for use in a wide range of industrial hydraulic applications requiring dependable, clean, and environmentally considerate performance.
