Mobil Dte 27
Mobil Dte 27 are superior performance anti-wear hydraulic oils designed to meet a wide variety of hydraulic equipment demands. These oils provide long oil / filter life and optimum equipment protection, reducing both maintenance and used oil waste costs. In addition to meeting the critical requirements of other hydraulic system parts such as servo-valves with narrow tolerances and high precision numerically controlled (NC) machine tools, as well as meeting the demanding needs of hydraulic systems operating with high pressure and high flow pumps under difficult conditions, together with major hydraulic manufacturers they have been developed. These are products that allow for unmatched performance with a single product, use designs compatible with a wide variety of metals, and meet the performances in the harshest operating conditions required by a wide range of hydraulic system and component manufacturers.
Mobil Dte 27 is formulated with high quality base oils and a maximized additive system capable of neutralizing the formation of corrosive materials. They are designed for systems in harsh operating conditions where high levels of anti-wear and film strength protection are required, as well as formulated to work for operating conditions where non-wear hydraulic oils are generally recommended.
Features and Benefits
Mobil Dte 27 hydraulic oils offer the ability to extend oil and filter change intervals with their unmatched oxidation resistance. The high level of protection against wear and excellent film strength properties can provide unmatched equipment performance that is not only limited to a reduction in the number of breakdowns but also increases production capacity. Thanks to their controlled water separation feature, these oils work smoothly in environments with very little water and they easily separate large amounts of water.
