Polishing module

Condensation in diesel fuel can cause bacteria growth and contamination.

Parker Energy Systems’ new FPM-050 Fuel Polishing Module removes emulsified water, thus preventing corrosion, maximizing filter effectiveness and reducing the need for fuel treatments and additives.

The FPM-050 is a recirculation system with a solid-state pump and a built-in Racor filter that can polish up to 50 gallons of fuel daily. It consumes 150 mA at 12 VDC and can be powered by a solar panel. It incorporates an automatic bypass valve that eliminates the need for manual switching and the manufacturer says it’s compatible with diesel, biodiesel and kerosene. The FPM-050 can be retrofitted to existing diesel fuel systems, either in line with the main fuel filter/water separator or as a dedicated fuel maintenance loop. It retails for $587.
