Puritech’s mission

Our company PURItech has a mission to purify exhaust gas from all kinds of combustion engines. PURItech stands for:

  • Cleanliness
  • Reliability and
  • Innovation

in Emission Control.

  • We have developed into a leading company in bus-retrofitting with PURINOX SCRT™ aftertreatment systems. And recently, we started retrofit of refuse trucks with SCRT . We are always committed to use the latest technology available to reduce exhaust emissions to the absolute minimum. Founded in 2001 by Bernhard Kahlert, the company experienced rapid growth with Diesel particulate Filter Systems (DPF). An extremely broad range of those filters is available for construction machinery, trucks and buses, trains and ships, as well as combined heat and power plants.


Since 2018, the company has become a 100% subsidiary of the globally expanding Chinese automotive supplier YINLUN.
