Purefi DPF+SCR ATC with active temperature control is a one of the most effective systems on the market and can operate even at extremely low exhaust gas temperatures with high NOx reduction levels.

• SCR with high NOx reduction, even when exhaust gas temperature goes periodically below 240 deg.C.
• With Purefi SCR ATC (Active Temperature Control) it is possible to heat up the SCR system to a steady temperature above 230-240 deg. where the system is highly effective.
• Avoid Urea crystallization with Purefi ATC.
