GreenTRAPTM Diesel Particulate Filter



Nett Technologies Inc. receives California ARB Verification for its GreenTRAPTM Diesel Particulate Filter

MISSISSAUGA, ON—July 29, 2009—Nett Technologies Inc. has received verification from the California Air

Resources Board (ARB) for its advanced GreenTRAPTM passive diesel particulate filter for off-road diesel

engines. The GreenTRAPTM reduces emissions of diesel particulate matter (PM) consistent with a Level 3 device

(greater than or equal to 85% reduction), complies with CARB January 1, 2009, nitrogen dioxide (NO2) limit and is

verified as a Level 3 Plus diesel emissions control device.

The California ARB has verified the Nett GreenTRAPTM system for its Airborne Toxic Control Measure (ATCM) for

stationary compression ignition engines. The verification covers stationary prime and emergency standby

generators and pumps powered by certified off-road diesel engines meeting 0.2 grams per brake horsepower

hour (g/bhp-hr) PM or less. The GreenTRAPTM catalytic diesel particulate filter utilizes a wall-flow filter monolith

coated with a proprietary catalyst to enable passive regeneration (self-cleaning) at typical diesel exhaust

temperatures. Specific engine criteria for which the GreenTRAPTM system has been approved may be found on

the Executive Order, which will be posted shortly on the California ARB website:

(http://www.arb.ca.gov/diesel/verdev/vt/stationary.htm).

Diesel engines emit a complex mixture of air pollutants, composed of gaseous, liquid and solid materials. The

visible emissions in diesel exhaust are known as particulate matter or PM, which include carbon particles

commonly referred to as "soot". In 1998, following a 10-year scientific assessment process, the ARB identified

diesel PM as a toxic air contaminant based on its potential to cause cancer and other health problems, including

respiratory illnesses and increased risk of heart disease. Health risks from diesel PM are highest in areas of

concentrated emissions, such as near ports, rail yards, freeways or warehouse distribution centers.

To reduce public exposure to diesel PM, in 2000, the ARB approved the Risk Reduction Plan to Reduce

Particulate Matter Emission from Diesel-Fueled Engines and Vehicles. Integral to this plan is the implementation

of control measures to reduce diesel PM such as the ATCM for stationary diesel-fueled engines. Among other

provisions, the ATCM established emission standards and fuel use requirements for new and in-use stationary

engines used in prime and emergency back-up applications. In addition to PM, the ATCM establishes emission

standards for hydrocarbons (HC), nitrogen oxides (NOX), non-methane hydrocarbons and NOX (NMHC+NOX),

and carbon monoxide (CO).

GreenTRAPTM diesel particulate filters utilize cordierite wall-flow monoliths to trap the soot produced by diesel

engines. The cylindrical filter element consists of many square parallel channels separated by thin porous walls.

The channels are open at one end and plugged at the other, which forces the particle laden exhaust gases to flow

through the walls. Gas is able to escape through the pores in the wall material. Particulates, however, are too

large to escape and are trapped in the filter walls and in the inlet channels. A proprietary catalyst is coated onto

the inside surface of the filter monolith. The catalyst lowers the soot combustion temperature allowing the filter to

regenerate. The accumulated soot is oxidized in the filter during regular operation of the engine. Due to the

presence of the catalyst, reductions in carbon monoxide (CO) and hydrocarbon (HC) emissions are also observed

and are similar to that of a standard diesel oxidation catalyst (DOC).

Information on the California Air Resources Board (ARB)

California's Legislature established the Air Resources Board (ARB) in 1967 to:

1. Attain and maintain healthy air quality.

2. Conduct research into the causes of and solutions to air pollution.

3. Systematically attack the serious problems caused by motor vehicles, which are the major causes of air

pollution in the State.
