The differences between fuel before and after polishing

It's a well documented fact that diesel fuel used for standby Generators sits in the tank for a long time waiting to be used.

During this period (about 6 months after delivery) the tank will condensate water into the fuel (which sinks to the bottom) In addition a bacterial growth begins within the fuel. This has the effect of creating a black sludge which settles in the bottom of the tank causing clogging of the fuel filter system.

If allowed to get into the Generator fuel system it can cause a reduction in power or system failure.

Under extreme circumstances the fuel can be rendered unusable, which at today's prices is very expensive problem when it has to be removed, disposed of and replaced.

Fuel Polishing is a way of removing the water and sludge (and any solid contaminants that may be present) from the fuel by passing it through a series of electromechanical filters. The process is a secondary one (ie it has no effect on the operation of the Generator) and is done by pumping the fuel out from the bottom of the tank, through the filter machine and then back into the top.

The sludge, water and solids are collected in a centrifuge bowl and removed during filtering. After the end of the process a biocide is then added to the fuel to retard the bacterial growth.

Fuel polishing will prevent any build up of sludge in the filters, prevent water entering the Generator (and reducing the power output) and generally ensuring a more reliable standby power system.
