The delivery of Ultimate D Cold-Flo will take the guess work and hassle out of treating individual trucks and storage tanks. Your fuel will arrive treated at the proper dose rate, ensuring your fleet gets total protection from icing and wax crystals and maximizing up-time.

Exceptional cold weather performance
Ultimate D Cold-Flo is formulated to enhance cold weather performance of all diesel powered equipment with special emphasis on equipment that experiences extended periods of shutdown. New and improved for winter fuels, Ultimate D Cold-Flo will deliver exceptional cold weather performance when and where required.
In addition, Ultimate D Cold-Flo may be continuously or batch blended into diesel fuel as a concentrate or as a stock solution. Proper blending and handling procedures must be followed due to the nature of all low tenperature operability additives.
Blend the additive with the fuel at temperatures at least 10F degrees above the cloud point of the fuel. Ensure the additive is at or above the minimun handling temperatures to avoid potential performance issues. Verify that the additive is completely dissolved into the fuel.

Our Proprietary Wax Anti-Settling Agent (WASA)
Ultra-Low-Sulfur Diesel (ULSD) is prone to gelling in cold weather meaning the solidification of ULSD into a partially crystalline state. A percentage of the fuel contains wax (paraffin) molecules. The more wax in the fuel, the higher the BTU value. However, exessive wax in fuel causes cold temperature operating problems.
Below the Cloud point, fuel begins to develop solid wax particles, giving it a cloudy appearance and if the temperature is sufficiently low, enough heavy wax platelets will form to block the fuel filter creating fuel starvation and resultant down-time.

Get ahead of cold weather performance issues for all diesel-powered equipment applications, with special emphasis on equipment subjected to extended shutdowns. Call Domestic today!
