Nett Technologies Inc. has received US-EPA verification of its BlueMAX 100 Selective Catalytic Reduction (SCR) system for controlling NO_x emissions from mobile nonroad medium and heavy duty diesel engines. The verification is a first of its kind issued for retrofit device under EPA ETV program.

Nett’s BlueMAX™ SCR system is designed to control nitrogen oxides (NO_x) emissions. The system uses a urea control strategy that relies on a NOx concentration measurement by a sensor positioned upstream of the SCR catalyst. Based on the NO_x sensor signal, in combination with an engine mass air flow sensor and temperature sensor, the necessary urea dosing rate is calculated by the control algorithm.

Feed forward NO_x sensor-based control strategy, enables the system to be ideal for retrofit applications. The system can be installed on a wide range of diesel engines and no additional engine calibration is necessary. The Nett BlueMAX™ SCR system also controls diesel particulate matter (DPM), hydrocarbons (HC) and carbon monoxide (CO).

Verification testing, over two test protocols; NRTC and 8-mode steady test cycles conducted at the Southwest Research Institute proved that the system reduced NO<SUB<X< sub> by 68-70%, PM by 12-30%. CO emissions were reduced by 87-94% and HC by 99-100%.

Nett’s BlueMAX 100 opens new opportunities to nonroad equipment users operating in nonattainment areas or where specified regulations exist for reducing NO_x.

Nett is known for its ability to provide direct retrofit (catalyst assembly replaces the equipment’s original muffler) solutions in some of the most challenging configurations where the catalyst may be nearly four times the size of the original muffler through an integrated approach of design engineering and manufacturing. The Nett BlueMAX™ SCR system is offered as a direct-fit design. This simplifies the installation and offers a customized cost-effective solution to a sophisticated emission control problem.

Reducing emissions from diesel engines is one of the most important air quality challenges facing the country. Even with EPA’s more stringent heavy-duty highway and off-road engine standards set to take effect over the next decade, millions of diesel engines already in use will continue to emit large amounts of nitrogen oxides, particulate matter and air toxics, which contribute to serious public health problems.

The Sylvite Group of Companies has reached a distribution agreement with Cervantes-Delgado, Inc. to distribute AirBlueFluids Diesel Exhaust Fluid in Canada, supplying this new product to fuel and transportation industries.  

Diesel exhaust fluid (DEF) is required in new diesel engines that utilize Selective Catalytic Reduction (SCR) technology to reduce NOx emissions.  In addition to the environmental benefits, users will experience up to a 5% improvement in fuel efficiency, optimized power and less cleaning of the diesel particulate filter.  Diesel exhaust fluid is a non-toxic, non-polluting and nonflammable high-quality urea solution which treats exhaust gas downstream of the engine to convert NOx into harmless nitrogen and water.

“Sylvite is very excited to launch API-certified AirBlueFluids Diesel Exhaust Fluid to the market.  As many customers seek practical solutions for the challenges of the new SCR technology, Sylvite is proud to serve them by leveraging our extensive fuel and chemical experience” assures Sylvite Vice-President Jeremy Goodfellow.

The Sylvite Group of Companies (www.sylvite.ca) is a strategic partner in providing supply chain value-added products and services to agricultural, industrial and government customers in targeted geographic markets.  The Company has international access to a variety of products and three decades of experience in bringing these items to Canada and delivering them in a value-added manner to our customers.  The Sylvite Group continues to systematically expand these core product and service competencies and increase both the geographic reach and the market segments served by the business.

Cervantes-Delgado, Inc. (CDI) was incorporated in 2001 for the primary purpose of marketing and distributing urea solutions for SCR and SNCR NOx systems.  With a management team that has over 100 years of experience in the marketing, distribution and engineering of urea systems plus over 30 years in catalyst manufacturing, CDI is proud to have the capabilities to service their customers from 31 different locations across the United States and Canada and continues to evaluate market conditions to strategically locate additional production facilities as near as possible to evolving markets.
