 DEF Dispensing Equipment Should Have a Closed System or Open System?



DEF represents Diesel Exhaust Fluid. It is a natural, nontoxic compound made out of 32.5% urea and 67.5% DI water. Utilizing a Selective Catalytic Converter (SCR) System, it changes over brown haze delivering nitrogen oxide into innocuous nitrogen and water fume. The vehicles will have an on-board DEF stockpiling tank of 16-30 gallons. A significant prerequisite of SCR System is the reliable topping off of these capacity tanks.


DEF quality is exceptionally fundamental. Its quality relies on the apportioning hardware utilized. There are assortments of DEF Dispensing hydraulic augers

gear on the lookout. While choosing the apportioning hardware, its value, strength, market stand and usefulness are vital elements to be thought of.


It is additionally vital to consider the framework that will be utilized in recharging DEF supply. There are two frameworks that can be utilized – Closed System and Open System


Shut System


Shut framework compartments have camlock couplings of valve that seals the opening on drums and sacks. This forestalls pollution of the DEF during transport, administering and removal periods of the holder life cycle. A common shut framework will have a plunge tube with the holder. A coupler or “administer head” is then associated nearby to the plunge tube for apportioning purposes. The pattern has moved to utilizing shut apportioning framework. It limits the capability of perilous synthetic compounds and fume openness. The alternate method for eliminating synthetic substances from an inflexible compartment is from the top while the holder is upward, utilizing a shut apportioning framework.
