ALPHASYN T RANGE
Synthetic Lubricating System Oil
DESCRIPTION
The Castrol Alphasyn T range of high performance, fully synthetic lubricants is designed for use in
central lubricating systems and gearboxes operating under arduous conditions - particularly at
elevated temperatures.
APPLICATION
Based upon synthetic hydrocarbons, these products exhibit outstanding thermal stability and
resistance to oxidation, excellent viscosity/temperature characteristics, high load carrying ability,
outstanding water ａnd air separation, low foaming tendency ａnd exceptional rust protection. Castrol
Alphasyn T was originally developed in ISO 150, 220 and 320 viscosity grades for the central
lubrication systems of paper-making machines. The range of viscosities available has been
extended to ensure that a product is available for virtually every application where a lubricating oil is
placed under extreme stress, from hydraulic systems (using Alphasyn T32 ａnd 46) through to large,
slow moving gears where Alphasyn T680 would be used. The outstanding oxidation stability of
Alphasyn T grades allows oil change intervals to be extended in circumstances where extreme
operating conditions results in a short service life when using conventional mineral oil based
lubricants ａnd can also allow demonstrable savings in more normal situations by reducing the level of
maintenance required. All products in the Alphasyn T range of lubricants have very low pour points
ａnd excellent viscosity/temperature characteristics, allowing their use in low temperature as well as
high temperature applications.
FEATURES BENEFITS
S Outstanding thermal stability and S Long oil life, reduction in downtime
resistance to oxidation.
S Medium load carrying ability, S Reduces energy loses
S Outstanding water ａnd air separation S Can be used in wet environments
S Exceptional rust protection S Longer machine
S Low foaming tendency S Ensures constant lubricant flow
S Low Volatility S Oil consumption due to evaporation reduced;
viscosity does not increase in service
NOTES
Castrol Alphasyn T is compatible with conventional seal materials ａnd paints ａnd is fully miscible
with mineral oil. This allows conversion of existing systems without the need for equipment
modification or extensive flushing procedures as can be required with other types of synthetic
lubricants.
Does not attack concrete in the event of spillages.
