Product Description
Mobil DTE 10M Series oils are supreme performance anti-wear hydraulic oils
engineered for wide temperature range applications. They exhibit optimum
flow characteristics at sub-zero temperatures and are resistant to shearing
and viscosity loss so that system efficiency is maintained and internal pump
leakage is minimised at high operating temperatures and pressures. These high
quality hydraulic oils with controlled low-temperature flow properties also
provide maximised anti-wear protection for high pressure vane, piston and gear
pumps. 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 OEM’s 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. Their multi-metal compatibility
properties allow their use with system components employing various alloys in
their designs.
The DTE 10M Series Oils are formulated with high quality base oils and a
carefully balanced super-stabilised additive system that helps neutralise the
formation of corrosive materials. They are designed to work with systems
operating under severe conditions where high levels of anti-wear and film
strength protection are needed, yet they are formulated to work where
non-anti-wear hydraulic oils are generally recommended. The DTE 10M Series
Oils have a history of proven performance in rotary screw compressor service
in the natural gas industry.
The DTE 10M Series Oils also have a history of proven performance in rotary
screw compressor service in the natural gas industry.
Features and Benefits
The Mobil DTE 10M Series hydraulic oils provide outstanding low and high
temperature performance. Their excellent oxidation resistance allows
extension of oil and filter change intervals while assuring clean systems.
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
controlled demulsibility permits the oils to work well in systems contaminated
with small amounts of water yet readily separate large amounts of water.
