HP PARTHAN 680 EE is a heavy-duty industrial gear oil specifically engineered for large, slow-speed gear systems operating under extremely high load and shock conditions. Its high viscosity base oil and advanced EP additive system provide an exceptionally strong lubricating film that protects gear surfaces from scoring, wear, and micro-pitting, even under boundary lubrication conditions. Designed for maximum energy efficiency, this oil helps minimize power losses while maintaining smooth, vibration-free gear operation. HP PARTHAN 680 EE exhibits superior oxidation and thermal stability, making it suitable for long drain intervals at elevated temperatures up to 107°C. The product’s anti-foam, anti-corrosion, and demulsibility features ensure reliable protection in wet or dusty industrial environments. It is recommended for use in heavy-duty enclosed gear systems in cement kilns, mining conveyors, and industrial gearboxes requiring ISO VG 680 performance.
