TRP CleanBlue is designed and tested specifically for today’s SCR systems, providing a fuel-efficient and cost-effective solution to 2010 EPA regulations. It is a non-toxic, non-polluting, non-hazardous and non-flammable DEF solution that can be used in all SCR after treatment systems, regardless of engine manufacturer.
1. What type of vehicles need DEF? Heavy- to light-duty vehicles with newer engines that use select catalytic reduction (SCR) technology need DEF.
2. Why is DEF required? DEF eliminates harmful exhaust emissions so engines meet Environmental Protection Agency (EPA) standards.
3. How does DEF work? Once injected into the hot exhaust gas stream, DEF vaporizes & forms ammonia and carbon dioxide. Then, with help from the SCR catalysts, the ammonia converts nitrogen oxide to harmless nitrogen and water.
4. Why is the quality of DEF important? It is important to maintain the concentration and purity of DEF ingredients so the SCR system functions properly and lasts longer.
5. How do I know the DEF I purchase will work? DEF products should display the American Petroleum Institute (API) certification standards & ISO 22241-1 specifications for purity and composition.
6. How much DEF will I use? Use approximately 2 gallons of DEF per every 100 gallons of diesel fuel, depending on vehicle operation, duty cycle, etc.
7. Does DEF require special handling? No, DEF is non-toxic, non-polluting, non- hazardous and non-flammable. It is safe to handle and store, and poses no serious risk when handled properly.
8. How should DEF be stored? DEF should be stored in a cool, dry well-ventilated area & out of direct sunlight. Optimum storage temperature is 77° F (25°C).
9. Is DEF stable? Shelf life can be in excess of one year when stored in moderate temperatures. In either hot or cold extremes shelf life can degrade to six months.
10. What happens if DEF freezes? A 32.5% DEF solution, comprised of urea & water, will begin to crystallize & freeze at 12° F (-11° C). Urea & water freeze at the same rate, ensuring that as it thaws, the fluid does not become diluted or over-concentrated.
