Nett Technologies
Nett Technologies is a manufacturer of catalytic emission control products specializing in exhaust pollution control for construction and mining machinery, industrial forklifts, generator sets, urban buses and trucks.
A catalytic converter is a device that uses a catalyst to convert three harmful compounds in exhausts into harmless compounds, such as water and carbon dioxide. A catalyst increases a natural reaction.
The three exhaust compounds are:
- Hydrocarbons – in the form of unburned gasoline
- Carbon Monoxide – formed by the combustion of gasoline
- Nitrogen Oxides – created when the heat in the engine forces nitrogen in the air to combine with oxygen
Carbon Monoxide is a fatal poison for any air-breathing animal. (CO)
Nitrogen Oxides leads to smog and acid rain. (NOx)
Hydro Carbons produce environmentally unsafe smog. (HC)
The catalyst also converts Diesel Particulate Matter (DPM) which consists of soot, ash, dirt, sand and dust.
So A Catalytic Converter heats up and then increases the reactions of CO, HC, NOx and DPM. The higher the temperature, the better the catalyst works. A minimum exhaust temperature of 200°C is needed for “light off” of the catalyst. The higher the temperature of the exhaust is, the more efficient the catalyst will be.
They can be used and are efficient, on all CNG, LPG and Diesel Petrol engines.
Particulate Matter FiltersCordierite or silicon carbide "wall-flow" monoliths coated with a catalyst to lower the soot combustion temperature. Over 90% reduction of particulate emissions. Self-regenerates at elevated exhaust temperatures (325-400°C). Requires a hot duty cycle for proper operation. Used on heavy-duty mining equipment. For more information, click here |

Diesel Oxidation CatalystsCatalytic converters for retrofit diesel applications. Available in several standard sizes. High reductions of carbon monoxide and hydrocarbons in diesel exhaust. Significant reduction of particulate emissions through the elimination of the organic portion of diesel particulates. Efficient elimination of diesel odor. For more information, click here |

Catalytic MufflersDirect-fit replacement of original mufflers for the emission control of LPG-powered forklift trucks. Catalyst is built into the muffler. Reduces carbon monoxide (CO) and hydrocarbon (HC) emissions to comply with occupational health and safety standards. Three-way systems reduce nitrogen oxides in addition to CO and HC. Propane exhaust odor is eliminated. For more information, click here |

Exhaust Gas DilutersExhaust gases forced through a circular gap mix with air through the Coanda effect. Dilutes, cools, and projects gases away from their source. Commonly used in applications where a maximum exhaust temperature is regulated by law or high concentration of pollutants in the proximity of their source is a nuisance.
