Mobil DTE™ 20 Series

Hydraulic Oils

Product Description
Mobil DTE™ 20 Series oils are supreme performance anti-wear hydraulic oils designed to satisfy a wide range of hydraulic equipment requirements. They provide long oil/filter life and optimum equipment protection reducing both maintenance costs and product disposal costs. They were developed in conjunction with the major builders to meet the stringent requirements of severe hydraulic systems using high pressure, high ouTPUt pumps as well as handling the critical requirements of other hydraulic system components such as close clearance servo-valves and the high accuracy numerically controlLED (NC) machine tools. These products meet the most rigorous performance requirements of a wide range of hydraulic system and component manufacturers using various multi-metallurgy designs allowing a single product with outstanding performance characteristics.

The DTE 20 Series oils are formulated with high quality base oils and a sUPEr-stabilised additive system that neutralises the formation of corrosive materials. They are designed to work with systems operating under severe conditions where high levels of antiwear and film strength protection are needed, yet they are formulated to work where non-antiwear hydraulic oils are generally recommended.

Features and Benefits
The Mobil DTE 20 Series hydraulic oils provide outstanding oxidation reSIStance allowing extension of oil and filter change intervals. Their high level of anti-wear properties and excellent film strength characteristics result in exceptional equipment performance that not only results in fewer breakdowns but helps improve production capacity. Their detergency and keep clean properties offer service over a wide range of system cleanlinesses while their controlled demulsibility permits the oils to work well in systems contaminated with small amounts of water yet readily sePARate large amounts of water.
