Yes, several departments have placed Novacool UEF directly into their tanks without any problems. Novacool UEF is usable with eductors, injectors, CAFS, or batch mixed; it’s non-corrosive and has no adverse effects on tanks, pumps, valves, and portioning equipment. Batch mixing is particularly necessary for departments that have older trucks or smaller brush trucks that may not have foam-proportioning systems. Novacool UEF is applied at 0.5%. A 500-gallon tank of water only requires 2.5 gallons of Novacool. A brush truck with a 250 gallon tank only needs to carry (1) five gallon bucket of Novacool UEF. This (1) five gallon bucket will treat 5 tanks of water at 0.4%. Novacool can be used all the way down to 0.2% for certain class A fires and still be effective.
