BlueMAX™ VOLT - Technology

The BlueMAX™ VOLT is an emission control system consisting of a Diesel Particulate Filter (DPF) upstream of a Selective Catalytic Reduction (SCR). It is designed to control emissions of both Particulate Matter (PM) and Nitrogen Oxides (NOx) from medium and heavy duty diesel engines in stationary applications. The system uses a proprietary catalyst on the inner surfaces of the DPF walls which reduces the regeneration temperature and therefore allows the system to passively regenerate in favorable engine exhaust operating temperatures. When temperature is not sufficient for passive regeneration, a set of electric heater coils are used to increase the exhaust temperature for active regeneration. An Electronic Control Unit (ECU) evaluates the system parameters such as temperature, pressure and exhaust mass flow rate in real time and uses these values to predict and activate the regeneration cycle.

In the Nett BlueMAX™ VOLT, NOx is reduced over the SCR catalyst through chemical reaction with Diesel Exhaust Fluid (DEF). The SCR sub-system consists of the SCR catalytic converter, a DEF dosing unit, and the DEF tank (see diagram). The DEF control strategy relies on NOx concentration measurements by a sensor positioned upstream of the SCR catalyst. Based on the NOx sensor signal in combination with an engine mass air flow sensor and temperature sensors, the ECU calculates the amount of urea which needs to be injected for optimum NOx reductions. The NOx sensor-based control strategy makes the system very suitable for both original equipment and retrofit applications. System calibration (i.e. engine mapping) is not required and the system can be installed on a wide range of diesel engines, both mechanically and electronically controlled.

The Nett BlueMAX™ VOLT ECU continuously monitors and measures the performance of all system sensors and components. In the event of malfunction, the ECU will indicate the existence of a problem to the operator via the system display. The system provides up to 95% emissions reduction in Particulate Matter (PM), Oxides of Nitrogen (NOx), Carbon Monoxide (CO) and Hydrocarbons (HC). 

BlueMAX™ VOLT - Performance

Nett Technologies’ BlueMAX™ VOLT is an Active Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) system which is designed to control emissions of Particulate Matter (PM) and Oxides of Nitrogen (NOx) from medium and heavy-duty diesel engines in stationary applications. The system contains a set of electric heater coils that are used to increase the temperature of the exhaust for active regeneration allowing the system to run without relying on engine exhaust temperatures.

The wall-flow DPF traps PM/soot emissions emitted by the diesel engines. The cylindrical filter element of the device consists of many square parallel channels running in axial direction, separated by thin porous walls. A proprietary catalyst is wash-coated on the inner surfaces of the monolith channels. The inner catalyst lowers the PM oxidation temperature allowing filter to passively regenerate at lower temperatures. When the exhaust temperature is not sufficient for passive regeneration, an active regeneration will be automatically triggered. During active regeneration, the electrical control unit utilizes excessive power of your generator in a controlled manner to increase the exhaust temperature to levels that can safely oxidize collected soot in the DPF. NOx is reduced over the SCR catalyst through chemical reaction with a reducing agent 'urea' commonly referred to as Diesel Exhaust Fluid (DEF). The urea control strategy relies on NOx concentration measurements by a sensor positioned upstream of the SCR catalyst. Based on the NOx sensor signal, in combination with an engine mass air flow sensor and temperature sensors, the Electronic Control Unit (ECU) calculates the amount of urea which needs to be injected for optimum NOx reductions.
