Products

Logical Clean Air Solution's Substrates are extruded honeycomb monoliths containing thousands of parallel channels. The channel walls are coated with precious metal catalysts that convert noxious emissions into less harmful gases and water vapor. Ceramic substrates are used at the heart of catalytic converters to help reduce exhaust emissions from Diesel and gasoline-powered engines. Our Ceramic substrates and filters are used around the world in diverse applications across the pollution abatement industry to help customers achieve efficiencies, reduce particulate matter, and improve performance in new and retrofit stationary emissions control systems.

Our products are available in cell densities, diameters and lengths that are among the most diverse in the industry.

Our substrates enable highly efficient emissions control systems by offering:

• High surface area
• Low pressure drop
• Rapid light-off
• Thermal-mechanical durability
• System cost efficiency

High Temperature Durability

Exhaust gases can reach extreme temperatures and are highly variable, producing thermal stresses within the converter. The ceramic composition used in our substrates is highly resistant to thermal shock resulting from sudden and severe temperature changes. In addition, these advanced substrates can operate effectively at temperatures of 1200C and can withstand spikes of up to 1400C.

Mechanical Durability

Cordierite Ceramic Substrates have proven mechanical durability. Their monolithic (single-piece) structure and cellular geometry promote stiffness and isostatic strength.

Thin-Wall & UltraThin-Wall Substrates

The higher geometric surface area of Thin-Wall & Ultrathin-Wall substrates contributes to lower emissions during steady-state catalytic converter operation. In addition, their lower mass facilitates quicker converter light off for more effective cold-start emissions reductions.

With their thinner walls, Thin-Wall & UltraThin-Wall substrates also offer the option of improved pressure drop performance. Compared to a 600/4 thin-wall substrate, and Ultrathin-Wall 600/3 substrate delivers approximately the same geometric surface area with 10% lower pressure drop.

Our diesel particulate filters utilize Advanced Cordierite or Aluminum Titanate wall-flow monoliths to trap the soot produced by diesel engines. The cylindrical filter element consists of many square parallel channels running in the axial direction, separated by thin porous walls. The channels are open at one end, but plugged at the other. This way the particle laden exhaust gases are forced 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.

Logical Clean Air Solutions provides Diesel Particulate Filters (DPF) for various applications:

• On-Road Light/Medium/Heavy-Duty Vehicles
• Power Generation
• Dust Control
• Mining Equipment
• Construction
• Marine
• Material Handling
• Locomotive

The diesel oxidation catalyst (DOC), or Two-Way, owes its name to its ability to promote oxidation of several exhaust gas components by oxygen, which is present in ample quantities in diesel exhaust. When passed over an oxidation catalyst, the following diesel pollutants can be oxidized to harmless products, and thus can be controlled using the DOC:

• carbon monoxide (CO),
• gas phase hydrocarbons (HC),
• organic fraction of diesel particulates (SOF).

Additional benefits of the DOC include oxidation of several non-regulated, HC-derived emissions, such as aldehydes or PAHs, as well as reduction or elimination of the odor of diesel exhaust.

The emission reductions in the DOC occur through chemical oxidation of pollutants occurring over the active catalytic sites. These processes can be described by the following chemical reactions.

(1) [Hydrocarbons] + O2 = CO2 + H2O

(1a) CnH2m + (n + m/2)O2 = nCO2 + mH2O

(2) CO + 1/2O2 = CO2
