NOW that new 2010 diesel-powered trucks are requiring diesel exhaust fluid (DEF) as part of the exhaust treatment system, new shipping arrangements are being set up to supply the diluted urea in larger quantities.
Oilmen's Truck Tanks Inc of Spartanburg, South Carolina, wanted the honor of designing and building the first DEF delivery truck tank in the nation. The result is this 3400-gallon stainless steel elliptical single compartment tank.
The tank shell is alloy 304-2B 12-gauge material with a 10-gauge bottom plate and 10-gauge dished and flanged heads and three baffles. The tank is fitted with 3" stainless sump, 3" air operated emergency valve and 2" stainless steel piping. The certified pumping equipment is in the driver side compartment — pump, meter, electronic register with in-cab slip printer, hose reel and 100 feet of 1½" DEF hose.
The DEF delivery tank is mounted on a 2010 Peterbilt 340 with Paccar PX-8 330-hp diesel engine, Allison 3000 automatic transmission, 20,000-lb front axle, 40,000-lb rear axle and air-ride suspension.
The DEF solution weighs about nine pounds per gallon. It is a non-toxic solution of 67.5% distilled water and 32.5% automotive grade urea. ♦
