Purifilter™

Purifilter™ from Engine Control Systems is an integrated diesel particulate filter and silencer, which efficiently removes particulate (PM) and gaseous pollutants, CO and HC.

When the exhaust passes through the micro-porous filter walls the soot particles are separated and collected. At the same time the catalytic coating oxidizes the gaseous pollutants (HC) and (CO) to carbon dioxide and water. The catalytic coating also lowers the ignition temperature of the soot to approx. 320° C and the collected soot is automatically burnt off during operation. At operating temperatures less than 320° C regularly the filter can be equipped with an electrical heater to burn off the collected soot.

The Purifilter ™ is intended for permanent mounting on vehicles and machines in heavy operation running regularly with exhaust temperatures exceeding 320° C. Temperature measurement should be performed if a vehicle's duty cycle is in question.

Option

  • A manometer which continuously monitors the backpressure.
  • A precatalyst reducing the ignition temperature to 280 - 300° C.
  • Purifilter™ Plus. Electrical heaters inbuilt in the inlet section for regular regeneration of the filter on the vehicle.
  • A Combiclean™ station for regular maintenance and cleaning of the filter.

The Purifilter ™ has been tested by AVL/MTC, Sweden, Millbrook Proving Ground, U.K., South West Research Institute, USA, Environment, Canada, VERT, Switzerland, verified by ARB, California and conforms to TGRS 554 standards, Germany, see Approvals below and Links.
