Fuel polishing system consumes less than 1W

Parker Hannifin's Racor Division is introducing an ultra-low-power fuel polishing system for use in with small diesel engines. The new system has been developed to remove the moisture and fine particles that accumulate in fuel tanks and lines, especially when the engine has been lying idle for extended periods. It prevents filtration systems from becoming clogged and protects the operation of diesel engines.

Fuel contamination can be a major problem; in particular, moisture and condensation forming in tanks and fuel lines can lead to the growth of bacteria and algae. Together with particles of debris forming from corroded surfaces or entering the fuel during refuelling, these can quickly affect the function of engine filters, reducing the efficiency of engines and, in the worst case, causing a complete failure of an engine.

Parker's latest fuel polishing system eliminates these problems by using extremely low-power piezo-electric pumping technology to circulate fuel from the tank through a specialised polishing filter and then either back to the tank or direct to the engine. Ideally, the system is set to run when engines are shut down, with the polishing unit steadily removing contamination in the fuel tank, ready for when the engine is next required.

The fuel polishing system can be set to run automatically and is capable of circulating up to 325 litres per day, with the system drawing less than 1.0W; typically only 1Ah is required to circulate 900 litres of fuel.
