 "Pressure at the fuel injectors has increased from 15,000 psi a few years ago to nearly 30,000 psi on new engines," says Pete Brown of Caterpillar''s engine applications group. "To get these higher pressures, fuel pumps are built to closer tolerances. Dirt in the fuel is like sandpaper, and it will definitely cause greater wear."To meet the challenge, Cat''s newest engines are equipped with increased water-sensing and fuel-filtering capabilities as well as a filter on the fuel tank breather. Primary fuel filters, once designed to remove 150-micron particles, are now rated for 10 microns. Secondary filters, once sized to remove 10-micron particles, are now rated for 2 microns. And the new high-efficiency filters can remove up to 99% of particles above those rated sizes compared to the 50% efficiency of older nominal filters. Filter improvements are also available for storage tanks. "Tank filters are typically rated at 10 microns nominal, so they take out 50% of particles greater than 10 microns in size. Tank filters with higher efficiencies, ratings down to 2 microns and water-absorbing capabilities, are now available," mccullochchainsawcoil says Gall. CHICAGO -- I don''t know how many of you took my advice to attend this year''s ASHRAE Show, but it sure was a whopper when it comes to attendance.Unfortunately, while the number of attendees continues to grow, the number of companies displaying their wares has continued to dwindle. This is because many of our industry''s largest players such as Carrier, Trane, York and others have opted not to participate simply because they feel that the results of the exposure they receive don''t justify the high costs involved in displaying. Beverage companies, including a major Florida mccullochchainsawcoil orange juice producer, are evaluating the valve for use in CIP applications, according to Dennis Richardson. He is president of SSOE Gateway, a Sarasota, Fla., mccullochchainsawcoil engineering design and construction firm that is helping bring the valve to market. Pressure variation in city water systems is a given, and mccullochchainsawcoil that raises questions about the efficacy of sanitation washdowns with automated systems. If pressure drops below the preset threshold, the CF valve will automatically shut down, preventing the CIP system from completing its cycle under less than optimal conditions.
