Navigating Cold Weather Challenges: Maximizing DEF Performance in CTL and Skid Steer Operations
Are you operating compact track loaders (CTLs) or skid steers in your construction or landscaping business? Whether you're a seasoned professional or just starting out, understanding how to handle Diesel Exhaust Fluid (DEF) is crucial for maintaining the performance and longevity of your equipment, especially during the cold winter months. Here are some essential tips to ensure the safe operation of your CTLs and skid steers:
1. Be Aware of DEF Freezing Point:
DEF, composed of 32% urea and 68% deionized water, can freeze at temperatures as high as 12°F. It's essential to know this freezing point to prevent potential damage to your equipment.
2. Allow Room for Expansion:
Like water, DEF expands when it freezes, increasing in volume by approximately 7%. Avoid filling the DEF tank completely in cold weather to prevent the container from cracking due to expansion.
3. Prevent Trapping DEF in Hoses:
After shutting down your equipment, wait for about 60 seconds before turning off the battery. This delay allows any remaining DEF in the hoses to drain back into the tank, reducing the risk of damage from freezing.
4. Thaw DEF Before Use:
If the DEF has frozen, allow the machine to run and heat the fluid with its built-in heating elements. Thawing the DEF before operation prevents potential damage to the equipment's SCR (Selective Catalytic Reduction) system.
5. Avoid Using Anti-Gelling Additives:
Resist the temptation to add anti-gelling additives to DEF. These additives can disrupt the functioning of the SCR system and lead to costly damage to its components.
6. Store DEF Indoors Whenever Possible:
To maintain its effectiveness, store DEF in a temperature-controlled, dry environment away from direct sunlight. If indoor storage isn't feasible, consider using heat blankets to cover the DEF tanks during cold weather.
7. Monitor DEF Levels Regularly:
Keep an eye on the DEF gauge just like you would with the fuel gauge. Operating equipment with low DEF levels can result in reduced operating speeds until the fluid is replenished.
By following these tips, you can ensure the safe and efficient operation of your CTLs and skid steers throughout the year, even in the coldest weather conditions. Proper DEF management not only protects your equipment investment but also contributes to a smoother workflow and increased productivity on the job site. Stay informed, stay prepared, and keep your equipment running smoothly for years to come!
