Mobil EAL™ Hydraulic Oil 32 and 46
EAL Hydraulic Oil
Product Description
Mobil EAL™ Hydraulic Oil 32 and 46 are premium quality, high performance hydraulic oils developed to meet the demand for environmentally acceptable hydraulic fluids. The products are based on synthetic, readily biodegradable esters. A high-performance, carefully selected additive package provides excellent anti-wear and extreme pressure (EP) properties as well as good thermal stability and corrosion protection. Inherently strong oxidation resistance helps to prevent gumming and deposit formation even at high temperatures. Because of the high natural VI of the base fluid and low pour point, the viscosity-temperature behaviour allows for a very wide operating temperature range.
Compared to vegetable oil based (HETG) products, HEES (Hydraulic Oil Environmental Synthetic Ester) fluids, such as the Mobil EAL Hydraulic Oil series, can give an overall improved performance and in particular related to higher operating temperatures and better thermal and oxidation resistance.
Features and Benefits
Mobil EAL Hydraulic Oil 32 and 46 provide excellent wide temperature range performance. Their exceptional anti-wear, lubricity and film strength characteristics assure performance in hydraulic and circulation systems operating under moderate to severe conditions. The ready biodegradability and virtually non-toxic nature of these products make them an excellent choice where leakage or spillage could enter environmentally sensitive areas. The inadvertent leakage of spillage of this product in environmentally sensitive areas could result in easier clean-up and lower remediation costs.

Applications
Mobil EAL Hydraulic Oil 32 and 46 are recommended where there could be accidental fluid loss into the environment or where surface water contamination should be avoided. Application areas include industrial, forestry and marine and particularly in mobile equipment. This can include waste water treatment plants, reservoirs, waterways, parkland, tunnel drilling, forest machines, dredgers, river sluices and harvesting machines, etc. On ships, applications could include bow thrusters, propeller systems and deck machinery.
Mobil EAL Hydraulic Oil 32 and 46 are also suitable for use in the power and energy industry, particularly in wind turbine applications.
There are some special handling procedures with the Mobil EAL Hydraulic Oil series. Whilst Mobil EAL Hydraulic Oil series is fully miscible with mineral oil based hydraulic oils, its biodegradability will be reduced if the two product types are mixed. It is always recommended to test for miscibility. Residual quantities of mineral oil should be kept at a minimum. Furthermore, paint finishes should be on 2-part epoxy system. Metals such as zinc and tin should be avoided wherever possible. The cleaning effect of these fluids can dislodge large amounts of dirt, which can shorten filter life. Water content during use should be ‹ 0,1%. Any collected water should be drained.
