Diesel exhaust fluid is becoming ever so present at truck stops and fuel dispensing facilities. More and more retailers are selling it simply because there’s a huge demand for the product.
If you own a business that regularly serves diesel powered vehicles, you might have thought about selling DEF too. Perhaps, you’ve already started planning for it and are close to the roll out. Or perhaps, you’re still exploring the idea and are yet to take concrete steps.
At whatever stage you might be, it’s advisable that you understand in advance how to store DEF properly so as to maximize its shelf life. It’s what many first-time retailers get wrong.
What’s the Standard Shelf Life of DEF?
DEF can last for a maximum of 2 years. However, that’s only possible if you store it under ideal conditions – and we all know achieving ideal conditions in any process is nearly impossible. So with DEF what you’re looking at is a shelf life, typically in the range of 18-20 months. If you store it properly, it should easily serve this period.
How to Store DEF the Proper Way?
There are a few things you need to keep in mind when storing DEF.
First, you need to use the right container. DEF contains deionized water. It can react with materials that contain ions. Therefore, you should use a chemically inert container for its storage. High-density polyethylene or stainless steel are the recommended options.
Second, be wary of the ambient temperature. DEF must not be kept at temperatures above 86°F (30°C); warmer temperatures can degrade the quality of DEF. Also, temperatures lower than 12°F (-11°C) should be avoided as they can freeze the fluid. Although, DEF recovers its properties once it is completely thawed, it can cause problems in terms of containment; DEF expands on freezing and can damage the storage container.
Last, but not the least, store DEF away from sunlight. The UV rays from the sun can disintegrate DEF and cause overheating. Both of these processes can reduce the fluid’s shelf life.
