The INDUS-GEAR BIO ES Series is a high-performance, environmentally conscious range of industrial gear oils based on biodegradable unsaturated fatty acid esters. Engineered for severe-duty gear systems operating in sensitive environments, this range delivers exceptional protection, durability, and sustainability.
The INDUS-GEAR BIO ES Series is ideally suited for use in sectors such as hydropower, forestry, mining, and wind energy – where performance cannot be compromised, and environmental responsibility is a priority. Achieving over 60% biodegradation in 28 days (OECD 301B), these lubricants offer a reduced ecological footprint in the event of leakage or accidental release, and meet the requirements of DIN 51517 Part 3.
Key Benefits
- Sustainable and Safe
Rapid biodegradability supports ecological safety in environmentally sensitive operations. - Enhanced Gear Protection
High natural polarity ensures strong adhesion to metal surfaces, improving micro-pitting resistance under extreme loads. - Extended Oil Life
Formulated for thermal stability and long-term performance, even in elevated temperature conditions. - Rust and Corrosion Resistance
Provides reliable protection across both ferrous and non-ferrous metals, including in moisture-rich environments. - System Compatibility
Miscible with most conventional gear oils, simplifying changeovers with minimal downtime. - Operational Efficiency
Excellent air release and water separation characteristics reduce foaming and help protect against cavitation in circulation systems.
Product Range
The INDUS-GEAR BIO ES Series is available in three viscosity grades to suit a wide range of gear system requirements:
- INDUS-GEAR BIO ES 150 (Product Code: 12730) – For applications requiring moderate viscosity and excellent flow at low temperatures.
- INDUS-GEAR BIO ES 220 (Product Code: 12731) – A balanced, general-purpose grade suitable for a wide range of industrial gear systems.
- INDUS-GEAR BIO ES 320 (Product Code: 12732) – A higher-viscosity option designed for systems operating under severe load conditions.
