Diesel Exhaust Fluid (DEF) dispensers – adding bulk DEF to cardlocks

Diesel Exhaust Fluid (DEF) dispensers – adding bulk DEF to cardlocks

We are going to continue to build this guide to help you determine some of the most important parameters when it comes to adding a new Diesel Exhaust Fluid (DEF) dispenser.

First, let’s survey the property.  We are looking for overall feel of the location, number of service lanes, existing dispensers, existing cardlock, and an understanding of where the future equipment could go.

As you walk the property, ask for existing volume of DEF if they’re expanding, or expected/projected volume of DEF if it is a brand new set up.

Some customers choose to have a tank right on the island, while others choose to have the tank remotely located.  These are questions that need to be clarified while on location.

Let’s focus on the Diesel Exhaust Fluid (DEF) dispensers:

DEF DISPENSER- SCENARIO 1

Do you have a need where a standard commercial DEF dispenser is good enough to handle the load.  Take our HDM Eco DEF dispenser with it’s built-in inventory management system (Wonderbox), this dispenser can be tied into an existing cardlock, as show in the picture below.  The drivers access the fuel and DEF by entering their information at the existing fuel master, and all transactions are captured at the existing fuel master.  Four service lanes were fitted with HDM Eco Diesel Exhaust Fluid (DEF) dispensers, as shown below.  Weights and measures components were not required at this location.

DEF DISPENSER- SCENARIO 2

This second site was surveyed and we were advised that the DEF dispensers needed to have weights and measures components. The WM PRO DEF dispenser was used here and also tied into an existing cardlock.  The drivers and vehicles are all controlled and tracked through the onsite cardlock, the WM PRO DEF dispenser serves as as a stand alone DEF unit.

The pulse feature of the dispenser is 1024/gal (standard) but configurable to  100:1, 1000:1.  With NTP approved oval gear meter and approved register with LCD display.

As you come across more opportunities to install new Diesel Exhaust Fluid (DEF) systems at card-lock locations, keep these points in mind when it comes to Diesel Exhaust Fluid (DEF) dispensers.

In summary:

  1. Make sure that the existing cardlock has an available slot to bring in another pump/hose.
  2. Make sure that enough physical space is available for the new DEF dispensers.
  3. Ask for a preference on tank location (island set up or remote)
  4. Is cold weather going to play a big role for the new set up?  Remember that DEF will freeze at 12°F, insulated and heated dispensers may be required.
  5. Accessories like pumps, solenoid valves, pressure switches, flexible pipe, etc… are all available.

We will discuss the tank options on the next entry… in typical fashion, if you want to add anything else to this list or if you have any further questions, do not hesitate to reach out.

    It’s really fascinating to know that DEF dispensers get to be frozen under the temperature of 12F which may require for insulated and heated dispensers to be used. I wonder if bulk chemical dispense unit is perfect for this kind of situation. I think this innovation is such a huge advancement for the tanking industry.
