Diesel engine fuel, when bulk stored for extended periods, can easily become contaminated with any number of foreign bodies from water and dirt to airborne microbes – a situation recognized by many of the major oil companies, who now recommend that fuel and fuel tanks are cleaned on a regular basis.
Contaminated fuel can have a serious impact on engine life, performance and reliability, in particular where high pressure common rail injection systems are used on modern engines.
The range of IPU fuel-polishing systems offer simple and reliable solutions to the problem faced by operators and rental companies who store diesel in environments subject to water ingress or general contamination.
In each case, fuel is pumped from the storage tank and ‘polished’ removing virtually 100% of water and all particles down to 5 microns before returning back to the tank, eliminating the expense of totally removing or replacing the fuel.

Mobile fuel polishing buggies
IPU fuel polishing buggies are lightweight mobile units designed for on-site cleaning of fuel tanks, drums and bowsers and incorporate a state-of-the-art fuel filter separator element to remove potentially damaging particulate contaminants and water from the diesel fuel. The units help protect engines from failure and unscheduled shutdowns and offer a high flow rate to ensure quick and effective filtration.
