 Castrol Alphasyn T
Product Data 
                                            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.
