Shell Tellus S2 MA
Industrial Detergent Hydraulic Fluid
Shell Tellus S2 MA fluids are high performance detergent based hydraulic fluids for use where
emusifiable fluids are preferred. Using proven ashless anti-wear technology they provide
reliable performance in applications where contamination by aqueous fluids, such as cutting
fluids, or where cleanliness or control of solid contaminants is important.
Performance Benefits
• Protection in severe environments
The established detergent and modern ashless antiwear technology in Shell Tellus S2 MA fluids
provides extra protection in challenging
environments by:
– Preventing water accumulation
– Dispersing solid contaminants
– Preventing corrosion in presence of water
– Providing low-friction anti-wear
performance
Outstanding anti-wear and load-carrying
properties in hydraulic and geared systems,
especially under high load and low speed
boundary lubrication conditions are demonstrated
by the high Brugger and FZG load values.
• Fluid life – Maintenance saving
Shell Tellus MA fluids have good resistance to
thermal and chemical breakdown to ensure
consistent performance and protection throughout
the fluid drain interval.
• Maintaining system efficiency
Superior cleanliness in severe environments helps
keep the hydraulic system functioning efficiently.
This is supported by excellent air release and antifoam characteristics.
In addition, Shell Tellus S2 MA provides excellent
filterability allowing the use of fine filters for extra
protection and long equipment life.
Smooth operation of the hydraulic system is
supported by the low-friction additive system that
helps reduce stick-slip behaviour under high loads
or poorly lubricated contacts.
Shell Tellus S2 MA has a minimum cleanliness of
max ISO 4406 21/19/16 class (ex Shell filling
lines) as defined by DIN 51524 specification for
extra equipment and filter protection. As
recognized by DIN 51524 specification, the oil
is exposed to various influences with transport
and storage that could effect the cleanliness
level.
Applications
• Industrial hydraulic systems
Shell Tellus S2 MA fluids are suitable for a wide
range of industrial and manufacturing applications
including:
– Injection moulding machines
– Electronically controlled hydraulic equipment
– Mobile equipment
– Headstocks and hydraulic controls in automatic
lathes (when a synthetic or semi-synthetic waterextendible metal working fluid is used)
Where low start up and high service temperatures
are encountered the use of Shell Tellus S2 VA 46 is
recommended.
