BlueMAX™ 100 Urea-Based Selective Catalytic Reduction (SCR) System Developed by Nett Technologies, Inc.

In a significant stride towards emission reduction and cleaner energy, the Environmental Protection Agency (EPA) has verified the Nett Technologies SCR system for use on nonroad, 4-cycle, non-EGR diesel engines. This announcement comes as part of the EPA's ongoing efforts to improve air quality and combat climate change.

The Nett Technologies SCR system, designed to reduce nitrogen oxides (NOx) emissions, will be equipped in various vehicles and equipment. Each installation will feature a monitoring system displaying warning lights and storing diagnostic error codes for easy maintenance.

To ensure the system's effectiveness, the vehicles or equipment should not be equipped with a crankcase oil burning system and should be well maintained. Exhaust temperature data logging is performed before each installation, and the temperature must be above 250°C for at least 30% of the normal duty cycle.

The retrofitted engines must operate on Ultra Low Sulfur Diesel Fuel (ULSD) with 15 parts per million (ppm) sulfur content for emissions reductions. Urea usage log and service log documentation will be collected by Nett Technologies and dealers on a quarterly basis each year. Customers are required to maintain urea purchase receipts and refill records for Nett Technologies to review.

The system will only be offered to centrally fueled fleets that have or are planning to have urea refilling capability. It is essential to note that the vehicle or equipment is not to be sold or operated in geographic areas where the urea solution may freeze (-11°C).

While the specific criteria for emission reductions with the Nett Technologies SCR system for nonroad, 4-cycle, non-EGR diesel engines, as verified by the EPA, are not explicitly detailed in the provided search results, general EPA knowledge suggests that such systems historically must meet EPA’s Tier 4 emission standards for NOx and PM.

For the Nett Technologies SCR system, EPA verification is expected to require documented NOx emission reduction levels demonstrated in standardized EPA test cycles for nonroad engines. Adherence to DEF quality standards per ISO 22241 is also crucial to prevent system malfunction that could compromise emission controls. Compliance with emission defect warranty and durability requirements over a specified operational period, as well as system controls minimizing NOx over a full range of engine operating conditions without exceeding emission limits, are also essential.

A Verification Letter from the EPA, issued on October 18, 2010, confirms the approval of the Nett Technologies SCR system. However, for precise criteria, the EPA Verification Statement or Certification document for Nett Technologies SCR system should be consulted directly from EPA’s verified technologies database or official publication.

This development marks a significant step forward in the fight against air pollution, paving the way for cleaner, more efficient nonroad engines. With the Nett Technologies SCR system, fleets can now reduce their emissions while maintaining their operational efficiency, contributing to a healthier environment for all.

Technology, such as the data-and-cloud-computing system, will be implemented to monitor the performance of the Nett Technologies SCR system equipped in various vehicles and equipment. This will involve logging and storing diagnostic error codes, urea usage, and service logs for easy maintenance.

The Nett Technologies SCR system, as verified by the EPA for use on nonroad, 4-cycle, non-EGR diesel engines, is anticipated to adhere to stringent standards in technology and data management to ensure effective emission reductions and compliance with EPA regulations.
