Shell Tellus Oils

sales — Wed, 02 Apr 2008 06:33:00 GMT

Shell Tellus Oils
Premium Quality Hydraulic Oils

Premium quality, solvent refined, high viscosity index mineral oil based fluids
generally acknowledged to be the 'standard-setter' in the field of industrial
hydraulic and fluid power lubrication.

Applications
* Hydraulic and fluid power transmission systems

* Bearing oils

* Spindle oils

Performance Features
* Improved thermal stability

* Excellent oxidation resistance

* Outstanding anti-wear performance

* Superior filterability

* Low friction

* Good water separation

* Excellent air release and anti-foam properties

* All round versatility

Thermal Stability
Modern hydraulic systems frequently operate in extreme conditions. As reservoir capacities are
often smaller nowadays, the tendency, in some cases, is therefore to operate at higher temperatures.

In these conditions, the thermal stability of a hydraulic oil, the measure of its ability to resist
degradation and sludging at high temperatures becomes particularly significant.

The accepted test of an oil's thermal stability is to maintain it at a temperature of 135 C in the
presence of steel and copper. After seven days the weight changes in the metals are measured
and any discolouration noted, and any sludge in the oil sample is recorded.

New Shell Tellus Oils gave excellent results in this test. Weight loss in copper and steel catalysts was negligible and there was virtually
no discolouration of the copper. No sludge was found in the oil sample.

Shell Tellus Oils have been tested for oxidation resistance, using the well known Turbine Oil Stability Test (TOST). In this test the oil is
heated at 95 C in the presence of water and oxygen with copper and iron as catalysts. The time taken for the acid value to reach 2 mg
KOH/g is then measured, or the acid value measured after 1000 hours. The test results showed that Shell Tellus Oils
have an oxidation life up to four times as long as some other anti-wear hydraulic oils.

Anti-wear Performance
When designing anti-wear hydraulic oils, priority is often given to the incorporation of anti-wear
additives which become active only under severe loading conditions.

As a result, some formulations overlook the need to provide effective anti-wear performance at low load.
Shell Tellus Oils

In the case of new, however,all operating conditions have been taken into account.

Shell Tellus Oils give outstanding results in the tough 35VQ25 test for anti-wear performance at
high load. In addition, exceptionally good anti-wear performance has been recorded in the Vickers V104C vane pump test at both high and
low load. Whereas many hydraulic oils fail to meet the requirements of one or other of these
Shell Tellus Oils tests, new are shown to deliver excellent anti-wear performance regardless of operating conditions.

Filterability
As hydraulic systems are designed with ever tighter tolerances, the filterability of an oil -- its
ability to pass continuously through a fine filter -- becomes more and more important.But filterability can suffer when a hydraulic oil is
affected by common contaminants such as water and calcium. Reaction products are formed which can block the filter.

However, extensive testing has demonstrated the excellent filterability characteristics of new Shell Tellus Oils,which eliminate premature blocking of the filter by reaction products.

Shell Tellus Oils T

sales — Wed, 02 Apr 2008 06:22:00 GMT

Shell Tellus Oils T
Premium hydraulic oil for wide temperature ranges

Premium performance, anti-wear hydraulic oils which incorporate a special viscosity index improver additive to enhance their viscosity/temperature
characteristics.

Applications
* Hydraulic and fluid power transmission systems subjected to wide variations in temperature or where low viscosity
change with fluctuating temperature is required.

Certain critical hydraulic systems can only tolerate small variations in viscosity with fluctuating temperature if efficiency and
responsiveness are to be maintained.Hydraulic oils, such as Shell Tellus Oil T, which exhibit multigrade viscosity characteristics may
be used to particular advantage in these circumstances.

Performance Features
* Very low viscosity variation with temperature
Special viscosity index technology minimises the oil's variation in viscosity with changes in temperature and provides
good pumpability at low temperatures.These features are particularly beneficial in hydraulic applications subjected to extremes of temperature.

* High shear stability
The 'VI' improver type is highly resistant to mechanical stress.

* Outstanding anti-wear performance
Proven anti-wear additives are effective in all operating conditions, including low and severe duty, high load situations.

* Excellent filterability
Minimal tendency to cause filter blockage in the presence of contaminants such as water and calcium.

* Oxidation resistant
Resist the formation of acidic products and sludge, even at high working temperatures.

* Corrosion protection
Provides long term protection against corrosion of both ferrous and non-ferrous metals.

* Rapid air release and anti-foam properties
Provide air release without excessive foaming.

Compatibility
The anti-wear additive technology used in Shell Tellus Oils T is based upon zinc which,although ideal for most hydraulic pumps,
should not be used in those of older design containing silver-plated components. Shell Tellus Oils S should be used for these applications.

Seal & Paint Compatibility
Shell Tellus Oils T are compatible with all seal materials and paints normally specified for use with mineral oils.

Guidance on Health and Safety are available on the appropriate Material Safety Data Sheet which can be obtained from your Shell
representative.

Shell Tellus Oils S

sales — Wed, 02 Apr 2008 06:14:00 GMT

Shell Tellus Oils S
Zinc-free hydraulic oils for severe duty

Shell Tellus Oils S are 'top-tier', anti-wear hydraulic oils formulated to be the ultimate 'high reference oil' in the hydraulics industry.
Based on advanced 'zinc and chlorine free' technology, Shell Tellus Oils S are formulated to ensure exceptional performance in hydraulic fluid power trans-
mission systems subjected to severe duty.

Applications
* Primary application in industrial, marine and mobile hydraulic and fluid power transmission systems.

Performance features
* Outstanding oil life
Typically two to four times that of many anti-wear hydraulic oils.

* Peace of mind
Through longer component life and trouble free operation.

* Ecologically acceptable
Zinc and chlorine free formulations unique to Shell.

Long life
The length of a hydraulic oil's life depends mainly on its ability to resist oxidation due to
heat in the presence of air, water and metal catalysts such as copper. Oxidation results in the formation of sludge and acidic products.

A standard test of oxidation properties is the Turbine Oil Stability Test (TOST), in which the
oil is heated at 95°C in the presence of water and oxygen with copper and iron as catalysts.

The test results are expressed as time taken (hours) for the acid value to reach 2 mg KOH/g.

In this test, Shell Tellus Oils S have an oxidation life of two to four times that of many other anti-wear hydraulic oils.

Vane pump wear performance
Shell Tellus Oils S have been subjected to a number of vane pump tests which are some of the most severe for evaluating steel-on-steel
anti-wear properties.

Excellent performance has been achieved in the standard industry tests using Vickers (V104C and 35VQ25M) and Denison (T6-C)
hydraulic vane pumps. In addition, outstanding performance is also observed when applying Shell in-house test conditions. These test the
fluids over the complete range of pump operating conditions. The results have proven that Shell Tellus Oils S are capable of
providing the ultimate protection under the extremes of operation found in real service.

FZG gear rig test
Gear rig tests are sometimes used for evaluating hydraulic oils and the best known is the FZG rig (Forschungsstelle für Zahnräder
und Getriebebau - Technical Institute for the study of Gears and Drive Mechanisms).

The rig utilises a pair of specially designed case-hardened spur gears and, for hydraulic oils, it is run at a pitch line velocity of 8.3 m/s,
with an oil temperature of 90°C. The test is carried out by running the gears for 15 minutes
in the test oil then weighing the gears, after which the machine is reassembled and the load increased. This procedure is carried out until at least 10 mg weight loss is recorded between the stages,
or until the gears appear scuffed.

Many anti-wear hydraulic oils fail around the tenth stage but Shell Tellus Oils S easily exceed this performance level.

Thermal stability
An oil's thermal stability is the measure of its ability to resist degradation and attack of metals at high temperature. An accelerated
test for this is to maintain the oil at a temperature of 135°C for one week in the presence of steel and copper.

Tests with Shell Tellus Oils S show negligible weight changes of the metals, whilst the steel remains bright and there is only slight
discolouration of the copper; many anti-wear hydraulic oils cause the copper to become black.

Piston pump performance
Many piston pumps utilise brass components and in particular brass slippers which fit onto

Shell Thermia Oil B

sales — Wed, 02 Apr 2008 01:55:00 GMT

Shell Thermia Oil B
Paraffinic Mineral Oil For Closed Heat-Transfer Systems

Shell Thermia Oil B is a paraffinic mineral oil heat transfer fluid for indirec closed fluid heat transfer systems operating at bulk temperatures up to 320°C
provided that there is adequate pump circulation to ensure that local film temperatures on the heater surfaces do not exceed 340 °C

Applications
* Heat transfer fluid for indirect closed fluid heat transfer systems operating at bulk temperatures up to 320°C

Peformance Features
*Good low temperature properties
Shell Thermia Oil B is fluid down to -18°C.Therefore no special precautions are necessary when closing down plant in cold
weather.Should the temperature fall below -18°C no expansion takes place.

*Low vapour pressure
Below temperatures of 320°C, the vapour pressure of Thermia B is less than atmospheric pressure. High pressure
pipework and heat exchangers, used with vapour phase heat transfer fluids, are therefore unnecessary.

*Good heat transfer characteristics
Shell Thermia Oil B has a relatively low viscosity with good temperature/viscosity characteristics which ensure high heat
transfer coefficients and consistent properties cover a wide temperature range.

Performance Benefits

*Low cost
*High thermal stability
*Operating temperature range from -18°C to + 320°C.
*Good oxidation stability
*Low viscosity to promote high heat transfer coefficients
*Good viscosity/temperature characteristics
*Low vapour pressure
*Non-corrosive
*Non-toxic

Resistance to Cracking & Oxidation

Mineral oils are subject to two forms of degradation during use:
1. Cracking or the breaking down of hydrocarbon molecules by heat. Here a large molecule ruptures into smaller
molecules. Some appear as volatile gases,while others are unstable and polymerise into non-soluble deposits. The rate of
cracking is insignificant until temperatures of around 320 C are reached. Above this temperature the rate rises steeply.

2. Oxidation or the reaction of hydrocarbon oil with atmospheric oxygen. At room temperature this reaction occurs very
slowly, but it accelerates rapidly with increasing temperature. Oxidation produces acids in the oil and, at a later
stage, sludge. The viscosity of the oil generally increases.

Shell Thermia Oil B is based on carefully selected, highly refined, high viscosity index
paraffinic base oils. It has exceptionally good stability at bulk temperatures up to 320°C.The rates of cracking and oxidation are very low,giving maximum oil life.
This assumes an efficient fluid heater with good pump circulation so that film temperatures on the heater surfaces do not exceed 340°C.

Service Life
The life of Shell Thermia Oil B in any system depends on the design and usage of the system. If it is well designed and not subjected to abnormal workloads the life can be many
years. It is important to monitor oil condition regularly as rates of change in physical characteristics are more significant than actual values. A sample should be taken from any
newly-filled system about one week after start-up to establish a datum. Further samples should then be taken every 6 months and the results compared with the previous samples.
The properties which should be monitored are viscosity, acidity, flash points and insolubles content.

outstanding lubrication performance under severe operating conditions, including improved energy efficiency, long service life and high resistance to micro-pitting.

Applications

* Enclosed industrial reduction gear systems operating under severe operating conditions,such as high load, very low or elevated
temperatures and wide temperature variations

* Worm gears

* Particularly recommended for certain‘lubricated-for-life’ systems

* Bearing and circulation systems such as calendars, where high bulk oil temperatures are found

* Plain and rolling element bearings

Shell Tivela S is not recommended for the lubrication of worm gears manufactured from aluminium containing bronze alloys. Advice on applications not
covered in this leaflet may be obtained from your Shell representative.

Performance Features and Benefits

* Excellent load carrying capacity and micro-pitting performance
Provides high levels of load carrying capacity even under shock loading conditions, along with high
resistance to micro-pitting (grey staining).These features provide benefits over mineral oil-based
products in terms of gear and bearing component life.

* Superior lubricant performance improving gear efficiency
Tivela S offers improved energy efficiency and lower operating temperatures in worm gear applications. Rig testing has shown efficiency
improvements of up to 15% in comparison with mineral oil-based products and 11% over other synthetic hydrocarbon-based lubricants.These results have been confirmed by OEM testing and
field experience.

* Excellent oxidation and thermal stability extending lubricant life
Resists the formation of harmful oxidation products at high operating temperatures,improving system cleanliness and therefore
reliability of the equipment. Tivela S is formally approved by Flender AG as providing a lifetime of
at least 20,000 hours or four years at bulk operating temperatures of up to 80°C.

* Longer service intervals
Extended component and lubricant life offers the opportunity to extend service intervals and to reduce maintenance and disposal costs.

* Excellent rust and corrosion protection of all metal surfaces

Specifications and Approvals
Meet the David Brown Type G specification.Fully approved by Flender AG.

Seal and paint compatibility
High quality epoxy paints are recommended, as polyalkylene glycols will tend to attack certain conventional paints. Tivela S has been found to be satisfactory with nitrile and Viton seal materials,
although Viton seals are preferred.

Change over procedure
Tivela S contains polyalkylene glycols and is not compatible with mineral oils or most other synthetic lubricant types. Care should therefore be taken when changing from such products to
Tivela S. The system should be flushed with the minimum quantity of Tivela S, operating under no load and draining whilst warm. Ideally, seals exposed to mineral oils should also be replaced.
Inspect the lubricant after a few days use. It is also advisable to ensure that oil systems are clean and free from contamination. Tivela S is also not miscible with some other
polyalkylene glycols, so caution is needed when topping-up. Generally the preference is to avoid mixtures by draining and refilling. Further advice can be obtained from your local Shell
representative.

Shell Turbo Oil GT

sales — Tue, 01 Apr 2008 02:44:00 GMT

Shell Turbo Oil GT
High Performance Industrial Gas Turbine Lubricant

Shell Turbo Oil GT has been developed for the most severe operating conditions imposed by modern, heavy duty industrial gas turbines.

Applications
• Power and industrial heavy duty gas turbines Shell Turbo GT is used as lubricating oil for main shaft bearings and mechanical gears as well as governor oil in the turbine control valves in modern gas turbines.
• Further industrial applications Shell Turbo GT may also be used for other industrial applications requiring a high
performance gas turbine oil, such as the lubrication of turbo compressors.

Advice on applications not covered in this leaflet may
be obtained from your Shell Representative.

Performance Features and Advantages

• Outstanding oxidation stability The lubricant's service life depends, to a great extent, on its oxidative stability. Excellent results
in both the 'hot oxidation test' (FTM5308) and the 'TOST' life test (ASTM-D943) clearly demonstrate
Turbo GT’s potential for extended service life compared to conventional mineral oil technology.

• Excellent thermal stability Higher bearing temperatures which are particularly severe during stop/start cycling
conditions, may lead to bearing deposits and the formation of harmful sludge in the system which subsequently may result in expensive “downtime” and reduce service life of system components.
Shell Turbo GT gives greater protection against thermal degradation and may hence significantly contribute to lower operating and maintenance costs.

• Extra high viscosity index Shell XHVI base fluid has inherently better viscosity/temperature characteristics compared to
standard mineral oils. Shell Turbo GT remains shear stable in service because no “VI” improvers
have been added. The high viscosity index of Shell XHVI gives the benefit of the fluidity of an ISO VG 32 grade oil at
start-up temperatures but higher viscosity compared to conventional oils at higher operating temperatures.

• Excellent air release characteristics Effective air release with a minimum of foaming tendency as required by modern gas
turbines.

• Low friction properties Shell XHVI base oil has shown a friction reducing effect in main bearings, resulting in
less generation of heat and lower bearing temperatures. This will reduce the chance of deposit formation in the bearing.

Specification and Approvals
Shell Turbo GT greatly exceeds the requirements from major turbine manufacturers specifications including:
• ISO 6743/5 ISO-L-TGB / -TGC DIN 51515-1, 51515-2 SIEMENS TLV 9013 04 ABB HTGD 90117S GEK 32568E SOLAR ES 9-224 U Class I

SHELL TURBO OILS T
Premium Lubricant For Modern Steam,Water And Industrial Type Gas Turbines

Introduction
Modern turbines generally impose more severe conditions on the oil than earlier types while at the same time requiring greater stability. Steam and bearing temperatures as
well as oil pressures are higher, and the rate of oil circulation is often more rapid while the output from power station is performed by fewer units of larger size. Greater
stability and reliability is therefore required of the oil and some authorities have issued more stringent specifications for turbine oils.

Steam Turbines
Spot temperatures in steam turbines can be as high as 200 C, but the highest local oil temperature in the bearings is usually about 100+ C. Oil enters the bearings at a
temperature of 40 C to 50 C and the oil flow rate limits the temperature rise through the bearings to 17 C to 20 C. These moderate operating temperatures assist in
giving the oil a long life which, with top-up, can be for the life of the turbine. Most problems in steam turbine oil systems are caused by contamination which can
effect demulsibility, air release, foaming and oxidation.

Aircraft-derived Turbines
The gas generator part of these units is derived from aircraft gas turbines and made by specialists such as Rolls Royce, Pratt and Whitney, Allison, GEC etc. Because of
the very high bearing temperatures mineral oils are unsuitable and only the approved aviation synthetic grades should be used.The “power” of “free-turbine” part of the unit has its own separate lubrication system and operates at temperatures similar to the heavy-duty gas turbines.For this system steam turbine oils are used.

Water Turbines
Oil temperatures in water turbines are low and although bearing loads are constant, they are very high. Steam turbine oils are used for the system lubrication and provide
the required good water separating properties and protection against rust and oxidation. Under certain conditions high viscosity oils are required for the hub of
Kaplan heads.
