The EECPC 3790A fully meets all proposed PMP requirements for Euro 5 and Euro 6 (VI) regulations for light and heavy-duty vehicles. It builds upon the proven rugged, reliable, and highly repeatable performance of TSI’s butanol CPC technology. The full-flow design incorporates new improvement and performance features, such as anti-spill/anti-flooding design, condensate removal system, and removable saturator for easy maintenance. EECPC 3790A has a lower particle size detection limit (D 50 ) of 23 nm to meet the PMP’s requirement for eliminating measurement of volatile and semi-volatile nanoparticles formed by nucleation of gaseous compounds.
