Whether your fuel oil is heavier or lighter than water, .J only Westfalia's two-stage Unitrol/Secutnol system assures ^ maximum purity even under widely varying feed conditions. IfcfV *** Here's why. On-demand vs timer-controlled de-sludging. JHL— Other oil purification systems are timer-controlled, which means they de-sludge only at pre-set intervals. If heavy seas stir-up the "muck" in your fuel tanks, the intervals may be too far apart. Result: dirt gets into your day tank and fuel lines, causing disastrous engine wear. . . In the Westfalia system, a unique sensor continuously monitors de-sludging intervals, discharging dirt and water only when the sediment-holding compartment is full. So there's no chance for dirt to get into your fuel because of too few de-sludgings — or fuel wastage from too-frequent de-sludgings. And either stage can be operated independently, thus adding even more flexibility. No water in fuel lines. With Westfalia's unique design, there's no way water can enter the clean fuel line. With other systems, this is a distinct possibility. Reliable purification. No matter how wide the variations in density or feed characteristics, you get the most efficient, reliable purification. Automatically, with no need for gravity disc changes. For maximum reliability we've substituted simplicity for complex electronics and intricate circuitry. Thus Westfalia purifiers are more dependable and much less likely to break down than other separators. Contact Centrico for the Westfalia system you need. Westfalia is proud to be part of the ongo- ing construction program of the new and growing U.S. Navy.
