Shell Water Detector is a device for determining the presence of
finely dispersed undissolved water in jet fuels at concentrations
lower than those normally detectable by visual examination. Water
dispersions of this type can result from the emulsification of a
water/fuel mixture during pumping or from precipitation of dissolved
water due to a fall in fuel temperature.
is it important to use the Shell Water Detector?
that jet fuels are free from dispersed or free water is a crucial
part of the quality assurance process. All jet fuels contain some
dissolved water which invariably comes out of solution as the fuel
cools during high altitude flights. Aircraft fuel systems are
designed to deal with these trace amounts and normally no
operational problems are encountered. In addition to this dissolved
water, jet fuels can contain significant levels of dispersed water.
Shell Water Detector is a reliable, convenient and cost effective
means to verify that the concentration of this dispersed water is
below the IATA recommended limit of 30ppm.
higher levels of water are loaded with jet fuel it is possible that
aircraft safety could be compromised
the fuel systems are not designed to handle unusually high levels.
On aircraft many systems, such as engines, are duplicated or even
triplicated for safety reasons. There is however usually only one
supply of jet fuel. Consequently, if there was anything wrong with
the fuel it could cause catastrophic results. It is therefore
essential that only clean, dry, on-specification fuel is delivered
on to aircraft.
Shell Water Detector is one of many products developed by Shell for
the aviation industry. Shell has been closely associated with the
development of oils greases and fluids for aircraft applications
since the earliest days of aviation. Today, the AeroShell brand name
is one of the best known within the aviation industry. Shell has
developed products to meet every significant engine and airframe
requirement for lubricants, and the range continues to be extended
to meet the performance needs of tomorrow's aircraft.
