A unique technology by PAC that is proven to provide the best precision in the market for determining DCN of all types of Diesel Fuels, Biodiesel, FAME, HVO, BTL, and GTL. It is a compact, easy to use, and fully automated analyzer, that offers excellent return on investment, and that is in compliance with today’s safety requirements. The CID 510 is in perfect correlation to ASTM D613, and approved as standard ASTM D7668. The excellent precision and correlation of this technology allows refineries to run their process closer to the specification limit for the cetane number. In addition the cost associated with cetane improvers is reduced, which ultimately increases a refinery’s profitability.
