Safe Handling & Cold Temperature

Safety in using Diesel Exhaust Fluid is achieved through operator training and strict adherence to the standard operating and maintenance procedures. Training should aim to familiarize truck and vehicle operators with the product and related processes as best possible. Producers and distributors of Diesel Exhaust Fluid can offer suitable maintenance and training packages to meet the needs of customers. Please contact your local Diesel Exhaust Fluid supplier for more information.

Diesel Exhaust Fluid is subject to freezing at the lowest temperatures. For example, Diesel Exhaust Fluid (made up of a 32.5% urea solution) may freeze at temperatures at or below 12° F. Although this temperature is encountered in colder climates during the winter season, it has not proven to be a problem for SCR-equipped trucks. Freezing does not impact its functionality and Diesel Exhaust Fluid is easily thawed within moments by the warmth of the engine.

Some automotive-grade urea producers are working on non-freezing additives and technologies. In the meantime, equipment systems are being developed and will be used to ensure that Diesel Exhaust Fluid thaws quickly. In fact, the EPA sees no problem in allowing it to reheat in the morning using the warmth of the engine when the truck is started.

While freezing may be touted as one of the bigger concerns with SCR technology, there have been no problems with freezing based on winter reliability and growth tests across Canada and North America. Furthermore, freezing has not been an issue among Northern European fleets in countries like Norway.
