Fuel Polishing

In addition to our tank cleaning services, we are delighted to offer a comprehensive fuel polishing programme. When combined with tank cleaning, fuel polishing can reduce equipment breakdowns, and lower costs on consumables such as filters and injectors.

The need for fuel polishing can arise from a multitude of scenarios, the most common of which is a build up of water and sludge in the base of a tank over a period of years. The waste in the tank then reacts with today’s modern blend of fuels to produce bacterial growth, commonly known as diesel bug.

Our range of available equipment allows us to offer both small and large scale services. The largest unit utilises a bank of six filters, beginning with 5 micron pots, before passing the fuel through a 1 micron filter to finish the process. Up to 10,000 litres of fuel per hour can be polished with a larger unit, it is also equipped with an internal particulate counter. This allows up to the minute monitoring of the fuel being returned to the tank.

The single pot mobile filter uses a 5 micron coalescing filter to remove water and particulates. This unit is capable of polishing up to 3000 litres per hour, and is ideal for smaller applications.

The difference following a tank clean

A point to consider however, is the tank in which your clean fuel is being returned to. Fuel tanks are inherently dirty environments, which are incredibly difficult to empty without accessing it internally. Putting polished fuel back into a dirty tank can often defeat the object of the exercise, so we would always recommend thoroughly cleaning the tank during the process.

 

 

 

The majority of tanks will have a fill pipe that extends to a striker plate at the base. An option being offered by many other companies involves putting a probe to the base of the tank and sucking out as much contamination as possible. Unfortunately this doesn’t deal with the often large build up of sludge at the ends of a tank, as a probe through the fill pipe simply cannot access it.

By cleaning the tank prior to returning the fuel, we are ensuring that your polished product remains clean rather than potentially becoming contaminated again.
