Salt Driers Assure Really Dry Fuel to Aircraft

Salt driers installed in an airport jet fuel delivery system reduced the fuel water content below saturation, lengthened filter life, and improved the performance of the downstream system components. Systems must be designed and operated to control salt carry-over. The high initial cost of salt driers compared with conventional filter-coalescers may be justified by low operating cost, improved microbial control, and customer satisfaction. Salt driers have a place in airport fuel treating.
