Key Performance Benefits
Application
HiTEC® 4557 cold flow improver is formulated to give optimum performance in middle distillates such as diesel fuel and heating oil and is designed to reduce the Cold Filter Plugging Point and pour point of treated fuels.
Recommended Dosage
HiTEC® 4557 is used to allow fuel manufacturers to cost effectively meet CFPP & Pour point specifications. The CFPP specification dominates the market and the CFPP level varies by geographic region. Treat-rate may vary depending on base fuels. However, the treat-rate should be in the range of 100 to 500 ppmv. For secondary treatment we would recommend a treat-rate of 500 ppmv.
