Standard & Custom Models

Direct-Fit Catalytic Mufflers

Nett Technologies has direct-fit catalytic mufflers available for hundreds of models of forklift trucks and other LPG powered equipment. The pre-designed models are in-stock or can be built and shipped within a few days. Catalytic mufflers are available to replace the original muffler for any LPG application. The emission control catalyst is built into the muffler and is selected based on the size of the engine. Catalytic mufflers are guaranteed to be a exact-fit replacement for the original muffler. The emissions reduction performance of catalytic mufflers is also guaranteed, provided the engine is well maintained and no excessive CO emissions are present.

Universal-Fit Catalytic Converters

For applications where a catalytic muffler is not required or desired, universal-fit catalytic converters are available. These in-stock, ready to ship products are available in a variety of sizes and with a range of inlet/outlet pipe diameters. Installation is not as easy as with direct-fit products but simply involves cutting-out a section of the equipment’s exhaust pipe and installing the catalytic converter in its place. The section of exhaust pipe chosen must be straight with sufficient clearance on all sides and be located upstream of the muffler.

OEM Products

OEM applications are developed in co-operation with the equipment manufacturer. The catalyst specifications are optimized to meet the particular emission targets and durability requirements. As well, the design of the muffler, including the catalyst substrate selection, canning technology, and noise attenuation requirements are optimized for the application. Development of OEM exhaust systems includes the design and fabrication of prototypes which are tested for emission and noise performance. Nett also provides compliance certification with the EPA or California ARB (Air Resources Board) regardless of whether a Nett emission control device is utilized. Three emission test cells are available for exhaust analysis of LPG, gasoline, CNG or diesel engines up to 250 kW (335 hp). See Engine Emissions Test Laboratory section for more information.
