RAVENOL Bio-Hydraulikoel HEES 46

RAVENOL BIO-Hydraulikoel HEES 46 is based on synthetic, easily biodegradable unsaturated esters and a powerful, environmentally friendly combination of additives which gives the product excellent properties regarding oxidation stability, corrosion, low temperatures as well as EP behaviour.

Compared with products of vegetable triglyceride base, RAVENOL BIO-Hydraulikoel HEES 46 has much better high temperature oxidation stability.

RAVENOL BIO-Hydraulikoel HEES 46 can be used year-round due to its outstanding low-temperature behavior and provides excellent wear and corrosion protection.

Application Note

RAVENOL BIO-Hydraulikoel HEES 46 is used wherever there is the danger of hydraulic fluidleaking into the ground or waste water. This includes all equipment operating in or near areas ofwater purification or water protection or near surface water, such as e.g. sewage treatment plants, dredging ships and floating dredges, lock hydraulics and river weirs, pipe and tunnel diving machines, - hydraulic aggregates in forests and on plains, earth moving machines in water collecting areas, forestry machines.
