Product description
Mobil DTE 20 Series oils are high performance anti-wear hydraulic oils designed to meet a wide range of hydraulic equipment requirements. They offer a long life of the oil/filter and an optimal protection of the equipment, reducing both the costs related to maintenance and those related to their evacuation. They have been developed jointly with major manufacturers to meet the stringent requirements of hydraulic systems working under severe conditions, using high pressure, high power pumps, as well as handling the critical requirements of other hydraulic system components such as tight tolerance servo valves and machines tools with numerical control (CN) of high precision. These products meet the most rigorous performance requirements of a wide range of manufacturers of hydraulic systems and components, who use various projects with different metallurgy, to which they allocate a single product with special performance characteristics.
Mobil DTE 20 series oils are formulated with high-quality base oils and a super-stabilized additive system that neutralizes the formation of corrosive materials. They are intended to work with systems operating in severe conditions, where high levels of anti-wear protection and oil film resistance are required, although they are formulated to work where hydraulic oils without anti-wear are generally recommended.
Features and benefits
Hydraulic oils from the Mobil DTE 20 series offer a special resistance to oxidation, allowing for longer oil and filter change intervals. Their high-level anti-wear properties and excellent film strength characteristics result in exceptional equipment performance, which directly results in fewer breakdowns, helping to improve production capacity. Their controlled demulsibility allows the oils to work well in systems contaminated with small amounts of water, being ready to separate large amounts of water.
Applications
- Hydraulic systems where the formation of deposits is critical, such as sophisticated Numerically Controlled (CN) machines, especially in cases of using servo valves with tight tolerances
- Where small amounts of water cannot be avoided
- Applications where sediments and deposits are formed with conventional products
- In systems that contain gears and bearings
- Systems that require a high degree of load-transport capacity and anti-wear protection
- Applications where corrosion protection through a thin film of oil is a quality, as in systems where small amounts of water are unavoidable
- Machines that use a wide range of components that use different metals
