Mobil DTE 21 (55 Gal. Drum)
Designed to meet the rigorous performance standards of a wide range of hydraulic system and component manufacturers, Mobil DTE 21 is a high-performance anti-wear hydraulic oil for use with high-pressure, high-output pumps as well as components such as close-clearance servo-valves and numerically controlled (NC) machine tools. Mobil DTE 21 is ISO velocity grade 10. This product’s exceptional oxidation stability and remarkable anti-wear and anti-corrosion protection outperforms conventional products in safeguarding hydraulic systems from deposit and sludge formation. Mobil DTE 21’s controlled demulsibility also protects systems from small or large quantities of water. It can be effectively used in systems employing a wide range of components using various metallurgies, under severe service conditions and extended drain intervals. Mobil DTE 21 also helps prevent thin oil-film corrosion, even in systems requiring a high load-carrying capability.
Features
- Excellent oxidation stability helps reduce maintenance downtime and costs by contributing to system cleanliness and deposit reduction, enable long oil and filter life
- Enhanced anti-wear and corrosion protection of system components using various metallurgy help extend component life and improve production capacity
- Controlled demulsibility protects systems from small and large quantities of water
- Keep clean properties reduce system deposits and sludge help protect equipment and extend equipment life, reduce maintenance costs and improve total system performance
- Quality reserve maintains performance features even under severe service conditions and extended drain intervals
Applications
- Hydraulic systems critical to deposit build-up or where sludge and deposits form with conventional products
- Hydraulic systems requiring a high load-carrying capability and anti-wear protection, and when thin oil-film corrosion protection is an asset
- Where small amounts of water are unavoidable
- Systems containing gears and bearings
- Machines employing a wide range of components using various metallurgy
