Besides the benefits that portable generators bring (handling power requirements for areas without national grid, in case of grid outage, etc.), this device also causes significant consequences for the environment because it uses diesel as fuel and uses diesel engines to operate.

To solve the problem of diesel engine emissions as well as help diesel generators develop and be widely applied while still ensuring environmental friendliness, the DS-9L diesel engine exhaust treatment machine was born.

Operating principle of Dr.Air DS-9T diesel generator exhaust gas treatment machine

Diesel engine exhaust treatment machine operates using SCR technology. When the device is running, the exhaust gas of the diesel engine passes through the honeycomb catalyst and the particulate filter. At that time, the polluting gases (HC, CO, PM, NOx) are rapidly oxidized under the effect of the catalyst coating on the surface of the carrier (urea solution), to transform into CO 2 , H 2 O and other substances that are more environmentally friendly.

Advantages of DS-9L generator diesel engine exhaust gas treatment machine

  • Easy to use
  • Easily connects to diesel engine exhaust
  • In addition to generators, DS-500kW is also applied to other equipment using diesel engines such as forklifts, tractors, …
  • Comprehensive treatment of pollutants in diesel exhaust including dust, NOx, HC, CO
  • Made of high quality metal, withstands high temperature of gas flow, ensuring durability
