The bulk Diesel Exhaust Fluid (DEF) equipment wave is now picking up speed. We are starting to see more and more demand for “what do I need” to help me get there? So, what a better way to kick off this next topic than to highlight some of the most basic elements that you will need, before you jump into the bulk Diesel Exhaust Fluid (DEF) wave.
Kicking off part I for this bulk Diesel Exhaust Fluid (DEF) equipment series, is your bulk DEF storage tank.
From what we have learned, and this is not a big secret to anyone, the best bang for your buck is a full load of bulk Diesel Exhaust Fluid (DEF). But what is a full load? Taking into account the weight of Diesel Exhaust Fluid at 9.1 lbs/gallon, a full load is typically considered around 5300 gallons.
Having said that, the tank of choice has been a 6500 gallon tank. That leaves you plenty of room to have some DEF left and take a new load.
Step 1: Secure a large volume tank, 6500 gallons or better. The tank size of choice (6500 gal) is 120” x 147”. So make sure that you have selected a good location and that you have the foot print needed to store your tank. Diesel Exhaust Fluid is 1.09 specific gravity, so a tank that is a standard 1.5 specific gravity is more than enough to handle bulk Diesel Exhaust Fluid (DEF).
Step 2: We now need to make sure that your tank can breathe. So it is highly recommended that a standard 2” vent is placed on your new tank if you are using a 2” fill port. Our rule of thumb is, if you are using a 2” fill port then you need a 2” vent. Consequently, if you are using a 3” fill port, you need a 3“ vent.
Step 3: How are you going to fill your tank? This really comes down to preference and it is best if you talk to your customer about it. There are several ways to do it but we will talk about the 3 most popular ways to accomplish this.
- 3 way valve. This set-up allows you to have 1x bottom opening, with the flexibility to fill and discharge from this configuration. We recommend that you place a ball valve after the bulk head fitting and before the 3 way valve for added security.
- Remote fill line. This fill line will run down the side of the tank and typically ends at chest height into a 2” camlock connection. The top of the line is secured to another bulk head fitting thus giving you the option to fill from the top of the tank.
- You can designate two separate ports at the bottom of the tanks. One port will be designated for fill while the other port is designated for discharging.
Now, this is all basic and most of you know this already. However, those of you that are new to this, keep in mind that unless you are dealing with someone locally that knows how to cut and weld polyethylene, the tanks come out of manufacturing with bulk head fittings only. The accessories are not provided.
This is important because if your preference is to have a fill line, then you need to have the tank delivered to a location that can retrofit the load line, secure it in place, and make all the connections before it gets to your customer. What’s the big deal? Well, the more stops the tank makes, the more logistics involved, the more costs associated with the system.
Now that you have your tank configured properly, what’s next? Now you need a pump that can help you take the product out of the tank to either fill totes, drums, or other larger tanks for delivery. I’ll show you how many of our customers have used a single TECALEMIT system that can satisfy most of your needs.
