Nett Technologies' BlueMAX NOVA 300e System Verified by California Air Resources Board (CARB)
Nett Technologies Inc. (Nett), of Mississauga, Ontario has announced that it has received verification from the California Air Resources Board (CARB) for their BlueMAX NOVA 300e System.
Nett's BlueMAX NOVA 300e diesel emission control retrofit system is verified to Level 3 Plus for diesel particulate matter (PM) reduction and Mark 5 for reduction of oxides of nitrogen (NOx). A Level 3 Plus PM reduction is greater than or equal to an 85% percent reduction and a Mark 5 level for NOx is also greater than or equal to an 85% reduction. The achieved reduction levels make this system the product with the highest emissions reduction levels verified for the retrofit market. The verification applies to Tier 1, 2 and 3 engines above 56kW originally certified without a catalyst or exhaust gas recirculation (EGR). It is an ideal product for prime power and peak power shaving generators.
The BlueMAX NOVA 300e incorporates both an active diesel particulate filter (ADPF) and a selective catalytic reduction (SCR) system. The Active DPF system consists of a diesel oxidation catalyst (DOC) positioned upstream of a catalyzed DPF, which traps the PM emissions from the diesel engine. The catalyst lowers the PM oxidation temperature allowing the filter to passively regenerate at temperatures above 300°C. When the engine exhaust temperature is not sufficient for passive regeneration, the DPF can be regenerated by means of HC injection over the DOC catalyst. NOx is reduced over the SCR catalyst through chemical reactions with ammonia produced by urea decomposition. The solution of 32.5% urea in water is known as diesel exhaust fluid (DEF), which is injected upstream of the SCR catalyst. The system is also equipped with a color display providing operator feedback and control that records both system and error codes, meeting the most stringent ARB requirements.
The system's installation is simple and efficient due to a preassembled modular kit that can be lifted into place by a forklift and mounted on the stationary equipment using only a few brackets. Installation then requires connections to the exhaust, electrical, fuel and a DEF supply.
