Good morning friends…
Dense and stubborn is not your standard language that is reserved to describe our winters… However; we are being faced with one of the worst winter storms in decades. For us folks in the south, yep; we are loading up with coffee and heating blankets since we do require a bit more TLC. For you guys right in the middle of the storm forthcoming, temperatures dropping well below freezing will not be unusual; try -40F.
So, this brings me up to the subject of Diesel Exhaust Fluid which freezes on the other side of this zero equation…+12F. That is a big gap between outside ambient temperatures and freezing point of Diesel Exhaust Fluid. Being that it is mostly water, it will become a block of ice if you don’t take some precautions.
Our biggest recommendation is to top off your tanks…. it is easier for DEF to freeze in lower volumes than it is when you have 500, 1000, 2000, or 5000 gallons. So, the old saying.. top it off and use common sense.
Some items to consider after topping off DEF tanks;
1. Bring it in… That’s right, if you can bring your tank inside ,do so now.
2. Remember the old saying, “Leave room for more”. Well, DEF will certainly expand when freezing in upwards of 5-7%.
3. Last, the question of quality once DEF freezes often comes up. There has been plenty of conversations on this and DEF has now been around long enough in countries like Norway where freezing and thawing of DEF does not affect its quality. You can read more here… link
In summary, if you have totes or mini bulk DEF tanks… you may consider topping them off during this winter, so hurry and call your local distributor!
Drop any other suggestions that you may have for the benefit of the groups… and for goodness sake; stay warm!
