Oilmen’s attended the 2011 FPMA in sunny Orlando this month.  DEF (Diesel Exhaust Fluid) was a popular topic and OTT brought three pieces of DEF equipment to the show.  The DEF1530 is a low volume system that is capable of flows up to 15-30 GPM.  It is available with or without Weights & Measures options.  This system was on display in three configurations – two portable units and one permanent setup for a shop or warehouse.
