Bio hydraulic oil - Biodegradable hydraulic oil
Generally referred to as "bio-hydraulic oil", these speciality hydraulic oils are high-performance lubricants that have a defined biodegradability due to their formulations. ADDINOL offers lubricants of biogenic origin as well as biodegradable lubricants in this category.
When working in sensitive areas or directly in our environment, far more aspects need to be considered than, for example, when selecting lubricants for stationary industrial plants. Especially when using heavy technology, such as dredging work in drinking water catchment areas, it is not only legal requirements that must be observed. Any contamination of all areas requiring protection should be avoided. Unfortunately, despite all preventive measures, accidents cannot be avoided. The use of high-performance lubricants with a composition that is rapidly biodegradable should therefore be a matter of course.

Our biodegradable hydraulic oils
The ADDINOL product range includes an extensive range of high-performance lubricants that are ideally suited for this application. The biodegradable hydraulic oil fully fulfils the lubricating properties of normal hydraulic oils and can also withstand harsh conditions (extreme temperatures, high workloads). You should pay particular attention to our exclusive NatureProof range.

Typical areas of application are
- Ecologically sensitive areas
- Water protection areas
- Agriculture
- Forestry
- Municipal economy
Biodegradable hydraulic oils are used as hydraulic fluids in hydraulic systems. They are primarily required for outdoor work when a loss of hydraulic oil from the system, e.g., due to leaks, cannot be ruled out.
