TermiNOx™ converts any open-loop LPG or CNG fueled off-road engine into a state of the art, digitally programmable, closed-loop, 3-way controlled engine that simultaneously reduces CO, HC, and NOx emissions by an impressive and verified 85-90+%*. In addition, the fuel efficiency of the vehicle 
typically improves by as much as 20% – combine these savings and reduced building ventilation costs and the TermiNOx™ system can provide you a full return on investment in as little as one year.
TermiNOx upgrades uncontrolled spark ignited engines used in industrial applications with state-of-the-art, electronic closed-loop fuel control and 3-way catalytic emissions control to reduce:
*Verified as the only LSI technology (large displacement engine spark ignited) by the Air Resources Board
2-Way Purimufflers™
A 2-Way Purimuffler integrates a catalytic converter, muffler and venturi to effectively reduce carbon monoxide (CO), and odor causing hydrocarbon (HC) from LPG, CNG or gasoline powered 
industrial equipment. Smaller industrial engines <25hp or built prior to 2004 may be operating without a closed loop 3-way control system such as TermiNOx.
In the engines, the air fuel ratio will vary from lean to rich depending upon the duty cycle of the engine. By incorporating a venture into the 2-Way Purimuffler, added air is continuously introduced into the exhaust to insure complete CO and HC oxidation while maintaining exhaust temperatures within safe limits.
2-Way Purimufflers feature direct fit for quick and easy installation as well as an electronic monitor to warn of potential engine problems which can lead to high emissions.
