The quickly biodegradable ECOSYNT HEES 46 hydraulic oil has long since established itself on the market as a high-performance hydraulic oil. The official listing by Bosch Rexroth confirms its suitability for use in state-of-the-art high-performance hydraulic systems (hydrostatics) employed in construction, forestry, agricultural, municipal and special machines.

ECOSYNT HEES 46 is a success story that began in 2007. As one of the first biodegradable hydraulic oils from MOTOREX to be widely used, it has impressively demonstrated that sustainability and performance do not have to be contradictory ideas in application. On the contrary, it shows that the duration of use can be significantly increased, which is really helps promote the sustainable use of resources. To this day, the hydraulic oil is used in countless machines around the world.

MOTOREX is constantly pressing ahead with the further development of its products to meet changing market requirements. In recent years, the performance range of many machines—including their hydraulic systems and hydrostatics—has increased significantly. This places stricter requirements on the hydraulic oil used. It has to cope with higher temperatures and pressure loads, as well as an increase in circulation rates and longer maintenance intervals.

Recognised performance for many years

ECOSYNT HEES 46 meets the latest technical and regulatory requirements. The formula is based on extensive research and numerous tests, and complies with the applicable specifications. It offers outstanding oxidation stability as well as strong wear protection and contains more than 25% regenerative raw materials. ECOSYNT HEES 46 also stands out from the competition thanks to its optimal elastomer and hose compatibility.

Responsible performance when used in hydraulic systems

ECOSYNT HEES 46 was designed for applications with strict environmental and technical performance requirements. The zinc-free, hydrolytically stable formula is particularly suitable for use in sensitive environmental zones and in hydraulic engineering.

Tested under the toughest of conditions – passed with distinction

Being listed by Bosch Rexroth is one of the most technically demanding certifications in the field of hydraulic oils, confirming the highest level of quality and performance. Many manufacturers explicitly stipulate that only approved hydraulic oils are to be used. The hydraulic oil is therefore ideally suited for use in state-of-the-art high-performance hydraulic systems. It offers reliable operational safety, particularly in areas such as construction, forestry, municipal infrastructure and power plants.

A reliable partner for OEMs and users

Bosch Rexroth’s listing is therefore more than just a technical milestone for MOTOREX. It is the expression of a long-term strategy with OEMs. With ECOSYNT HEES 46, manufacturers can include an environmentally friendly hydraulic oil in their operating manuals, approval lists and maintenance concepts, thus creating security for the after-sales service process.
