Nett Technologies Inc. developed a retrofit, three-way catalyst system for LPG-powered forklift trucks. The emission control kit includes a three-way catalytic muffler, an oxygen sensor, and a digital air to fuel ratio controller. The system efficiently removes carbon monoxide, nitrogen oxides, and hydrocarbons from LPG exhaust gases. It is intended for forklifts operating in confined areas, where it can improve the air quality and help to meet the occupational safety and health standards.
