ProEco® HE 501XE-15: Viscosity meets environmental standards

Conventional hydraulic liquids cannot be used in agriculture or forestry, as a single burst hose would be enough to cause significant environmental damage. Harvests can even fail if lubricants containing toxic, poorly-degradable active ingredients get into the soil. At the same time, substances used outdoors are often subjected to large differences in temperature and extreme working temperatures in general. What is needed is a lubricant that retains its viscosity even under such tough conditions. With ProEco® HE 501XE-15, BTC's range now includes a hydraulic oil that is made for precisely this kind of use. 

Synthetic esters: biodegradable

All the products in the ProEco® HE 501 series are quickly-biodegradable hydraulic oils that are produced based on synthetic esters, with a high content of naturally-growing raw materials. They therefore meet the strict requirements of the EU Ecolabel for hydraulic liquids and can be used in both stationary and mobile systems, such as forestry machinery, diggers, tractors, lifts and presses. 

For steel structures in contact with water, conservation areas and ski slopes

“Locks, weirs and lift bridges, i.e. all steel structures in contact with water, are ideal fields of use” says Gabriele Möller, Head of Business Management Europe at BTC for the Fuel & Lubricant Solutions division. “The new addition to the ProEco® HE range is an ideal lubricant for vehicles that operate in environmentally sensitive terrain.” This applies to both forest and nature reserves, where it is crucial that no harmful or even toxic substances get into the soil or water when leaks occur. ProEco® HE 501XE-15's lack of temperature sensitivity also makes it ideally suited to use in piste equipment in mountainous areas.
