The Castrol Performance Bio HE ESU hydraulic oil range (previously called Carelube HES) are based on carefully selected synthetic esters, which are highly biodegradable and recommended for use in situations where leakage or spillage may present a risk of harm to the environment.
Advantages
- Inherently biodegradable so ideally suited for minimising the impact to the environment should leakage occur (note: local legislation/regulations regarding the clean up of oil leakage/spills should always be followed)
- Environmentally friendly with low aquatic toxicity – rated WGK 1
- Very high viscosity index gives reliable operation and consistent response across wide temperature ranges
- Maximum component protection at cold start-up and at elevated temperatures
- Excellent anti-wear performance and lubricity maximises component life and ensures system reliability
- Seal, diaphragm and hose material compatibility similar to that of mineral oil, allowing easy changeover without component modification
