Hydraulic systems must be sustainable, efficient and reliable above all else. This is precisely where hydraulic oil comes in; after all, it carries the main responsibility for power transmission. Ensuring the durability of the hydraulic fluid – alongside delivering high performance, biodegradable products – is more pressing than ever before. ECOSYNT HEPR sets new standards for durability and tangibly reduces operating costs while increasing sustainability.
When analysing the overall operating costs of construction machinery, the service life of hydraulic oil is often underestimated. Instead, the focus is on the specifications and the price of filling itself. This, however, only provides a snapshot of the situation. With the added value of being able to extend the change intervals many times over, ECOSYNT HEPR is perfectly in tune with the spirit of the time.
The innovative HEPR formulation (Hydraulic Oil Environmental Polyalphaolefins and Related Products) uses special fully synthetic polyalphaolefins. These hydrocarbon compounds show particularly high chemical stability in comparison to many other commercially available hydraulic oils that biodegrade quickly (>50% regenerative raw materials) and to products based on ester liquids. ECOSYNT HEPR barely reacts and only reacts very slowly with water. Water can penetrate the hydraulic system due to high humidity, condensation or faulty seals, which in turn leads to costly defects. ECOSYNT HEPR’s high hydrolytic stability helps to prevent any reaction (such as corrosion or oxidation and subsequent acidification in these instances. This basic requirement, together with high power reserves, form the basis for its long-term use.
Laboratory analyses of hydraulic oil samples provide crucial information when it comes to extending the oil change interval. MOTOREX’s testing service uses cutting-edge measuring devices to examine the condition of hydraulic oil under the microscope. An insightful laboratory report provides information about the general condition of hydraulic oil by including data on water content, wear metals, ageing and viscosity. It builds the foundations for the decision of whether oil can continue to be used. However, it is important to note that this only applies to extending oil change intervals: Filters must still be replaced, and other maintenance work carried out, in accordance with the manufacturer’s instructions. Filling fluids are often only replaced because the amount of dirt or water in the hydraulic oil is too high. In such cases, the analysis report recommends complete fine filtration, which can extend the service life of high-quality hydraulic oils such as ECOSYNT HEPR. As a general rule, the more carefully a hydraulic system is monitored, the more efficiently it can be operated.
ECOSYNT HEPR 46 has recently undergone the demanding TOST (Turbine Oil Oxidation Test) at an independent laboratory. This test examines how many hours of operation it takes a hydraulic fluid to reach the maximum acidity level as specified in DIN ISO 15380. The minimum threshold to pass this test is 1,000 hours. When testing ECOSYNT HEPR 46, the clock was stopped at 12,000 hours – a first in terms of acidity level. This record-breaking performance shows just how much potential the groundbreaking HEPR technology has to offer.
