Clean Diesel Particulate Solutions for Low-Temperature Applications

• Best Available Control Technology (BACT) for low-temperature applications where DPFs are not feasible

• Equally effective for high-temperature exhaust streams

• Retrofit and OEM solutions

• Easily retrofitted into older higher-emission vehicles and stationary power systems that are expected to be in service for years to come

• Passive operation that consistently runs without unscheduled interruptions

• Reduces harmful primary emissions - 76% PM reduction - 89% HC reduction - 66% CO reduction

• No secondary emissions - no NO2 increase and overall 9% NOx reduction

• Innovative solution backed by more than 200 patents worldwide

Purifier™ e3 - 400Low-temperature emissions control

for 6 - 20 liter engines

Typical ApplicationsOff-RoadCranes, excavators, bulldozers, front-end loaders, scrapers, mining equipment, fuel/water trucks

On-RoadBuses, sanitation, urban delivery, tractor trailers

StationaryEmergency generation, distributed power, portable gensets

System Description• Bridges the gap between low-efficiency Diesel Oxidation Catalysts (DOC) and wall-flow Diesel Particulate Filters (DPF)

• Patented Purifier e3 technology based on a durable metallic wire mesh design making it suitable for rugged environments

• Effective emissions control in markets with variable fuel quality standards

• Designed as a replacement for the existing muffler providing equivalent sound attenuation characteristics

• Ideal for low attainment and low emission zones

Easy to Maintain• Patented system allows PM trapped in the filter to be continually oxidized even at low exhaust temperatures.

• Systems operating at 270oC or higher for roughly 10% of the time will initiate regular regeneration, allowing low back-pressure operation for extended periods of time with little or no maintenance.

• Cleaning the filter of residual ash buildup is easy. When indicated by the back pressure sensor module, simply unclip the V-clamp assembly to access the filter without having to remove the device from the equipment.

Sustainability and Bottom Line• Helps achieve sustainability goals by lowering the carbon impact of diesel applications - Reduces CO2 by 5-8% (or more depending on engine and application) - Furthermore, reduces secondary GHG emissions of PM, HC and NOx

• Improves fuel economy by 5-8% (or more depending on engine and application)

Verified Solution• EPA ETV-verified solution

Purifier e3-400 Components• Lightly catalyzed 250 mm OD wire mesh filter • Back pressure monitor - Physical dimensions: 21.4” dia. x 23.6” length • Platinum Plus® fuel-borne catalyst• Connection hardware • On-board doser and reservoir system

Particulate Solutions for a Complete Range of EnginesThe Purifier e3-400 is complemented by the smaller Purifier e3-100 to provide a family of emissions-reduction solutions with engine sizes rang-ing between 1.5 and 20 liters.
