TotalEnergies BIOHYDRAN SE 68 – Biodegradable Ester-Based HEES Hydraulic Oil

TotalEnergies BIOHYDRAN SE 68 is a rapidly biodegradable high-performance hydraulic fluid based on saturated synthetic esters. Developed as an environmentally friendly alternative to mineral oil-based hydraulic oils, it combines excellent oxidation stability, high wear protection and long oil drain intervals for heavy-duty applications.

Product Advantages
• Biodegradable (98% OECD 301 B)
• Over 80% renewable raw materials
• Very high thermal and oxidation stability
• High natural viscosity index (VI 142)
• Excellent shear stability
• CO₂-reduced formulation
• Excellent corrosion and wear protection
• Low foaming, excellent air release
• Seal compatibility (NBR, HNBR, AU, FPM)
• Suitable for long drain intervals

Typical Applications
• Hydraulic systems in construction and forestry equipment
• Agricultural and municipal machinery
• Work near water bodies or in nature reserves
• Mobile and stationary hydraulic systems
• Heavy-duty hydraulic circuits
