MobiClean™ DPF - Diesel Particulate Filter with active regeneration systems for Marine and Locomotive Applications
To meet ever-toughening regulatory requirements, the MobiClean – available in North America only from MIRATECH – is the one to bank on.
THE KEY: ACTIVE REGENERATION.
Most DPF's use engine exhaust heat to oxidize – or burn off – particulate matter in the diesel exhaust stream. With this “passive regeneration,” your engine exhaust must reach a temperature of 700 to 1050° F to oxidize soot trapped by the filters. At cold starts and with light loads, carbon and lube oil ash, as well as unburned fuel and lube oil, build up on the filters – and that build up boosts back-pressure on the engine.
The MobiClean gives you the option of active regeneration, using its own built-in heat-source. You don’t have to wait for warm-up or rely on heavy loads or load banks. It goes to work – trapping and burning 99 percent of diesel soot, including toxic sub-micron nano particles – as soon as you turn your engine on, with any engine load. For high-temperature applications, the MobiClean also comes without a built-in burner.
Either way, the MobiClean helps you meet the toughest particulate emission reduction requirements, regardless of what type of diesel fuel you use. High-dollar ultra-lowsulfur fuel isn’t needed. Easy to install and easy to maintain, it operates within OEM-specified engine back pressure limits – with low pressure loss. It even delivers sound attenuation and can replace a silencer or muffler.
HOW IT WORKS .
All soot filters remove particulate matter (PM) from diesel exhaust. Then, most take the “passive” approach, using high-temperature exhaust heat to burn off – or “regenerate” – trapped particles. At cold startup or with light loads, they simply can’t do the jobs you’ve bought them to do. The MobiClean difference: active regeneration. For light or variable load applications, it comes with its own heat source, built-in – so it works as soon as your engine starts up, and its performance is independent of engine load or exhaust temperatures.The MobiClean traps PM on the surface of a porous silicon carbide filter. Monitoring back-pressure on the engine and automatically activating a built-in diesel fuel duct burner, the system burns off particulates as they build up on the filter. This leaves only a small amount of ash on the filter surface that can be blown or washed off during regular maintenance. For high temperature, steady-load applications, the MobiClean also comes without built-in burners, using exhaust heat to burn off particulates.
COMPLIANCE : ASSURED.
Diesel soot reduction requirements vary from place to place for Power Generation, Locomotive and Marine applications. The MobiClean meets your needs for particulate emission reduction wherever you run your engines, no matter how strict applicable regulations may be. In fact, the MobiClean clears the air of 99 percent of diesel particulates – including toxic sub-micron carcinogens and nano particles. It also reduces visible smoke, which can be an issue for hospital HVAC systems, manufacturing applications – or facilities that simply need to be good neighbors.
THE DOLLAR-WISE SOLUTION.
With the MobiClean, you avoid the need to switch to costly ultra-low-sulfur fuel: the MobiClean keeps your operation on the right side of the soot-reduction non-compliance fine-line with regular No. 2 diesel fuel or any other fuel you choose. That alone can save you tens of thousands of dollars each year, compared with other soot-control solutions. The MobiClean operates within OEM engine back-pressure limits – with low pressure loss and minimal impact on engine performance and fuel consumption. Plus, you have only a single unit to install and maintain. There are no additional manifolds. The MobiClean even delivers noise reduction in addition to soot control, and can replace engine mufflers. Designed and built for rugged, long-term, failsafe operation, each unit is easily accessible and comes equipped with modular components, which cuts maintenance time, costs, and hassles – and reduces the need for operational shutdowns. A proven performer in power generation and locomotive applications, the MobiClean is tailor-made for gensets in the 500 kW - 7 MW range and can be retrofit or customized for OEM packages.
