Exhaust Aftertreatment
Exhaust Aftertreatment Specialists
Catalytic Support Systems manufactures exhaust aftertreatment components for leading OEM commercial vehicle and passenger vehicle brands. Meet your leakage reduction goals with our decades of experience in emissions control, helping customers go from 80L per minute to 0L.
Emissions Regulations
CSS Ltd have played a key role in developing products to meet strict Euro 4, 5 and 6 regulations. We have also, most recently, developed products capable of meeting the upcoming Euro 7 regulations.
DPF Seals and Gaskets
Choosing the right seals and gaskets for your DPF unit can have a huge impact on your exhaust aftertreatment process and drastically reduce emissions. You can work with our team of experts to design gaskets that will fit your system perfectly and meet your emissions requirements.
Your designs will then be brought to life quickly and cost effectively with our in-house tooling capabilities.
Large Variety of Materials
1
Knitted Wire Mesh
The original material, for which we are known, pure standard knitted wire mesh can be manufactured from all grades of stainless steel or exotic alloys depending upon the required temperature tolerance. The mesh is compressed down to the shape, size and density that you specify.
2
Graphite
Graphite gaskets and seals are available as either pure graphite, smooth surface, pure graphite surface which is reinforced with wire mesh, or rough surface, which is wire bound graphite offering a dynamic slip. All of our graphite components can be compressed to the shapes and sizes you require.
3
Silica
Wire bound silica DPF gaskets and seals are great for reaching higher temperatures and for sealing against soot and harmful gases. We are currently the only company in the world that can manufacture this kind of DPF gasket / seal. Ensure that you do not get this product confused with the cheaper fibre glass alternative, as it allows leakage and reduces the effectiveness of the DPF unit.
4
Mica
Mica gaskets are extremely effective at tolerating chemically corrosive environments and can manage a decent amount of heat. These gaskets are available as pure mica and wire bound mica.
5
Carbon / Metal
Carbon / metal gaskets are resistant against heat and chemicals used in the automotive system. These can be manufactured as per your drawings to any shape and size and can include tabs in your specified areas.
Spacer Rings
Along with reducing emissions, CSS Ltd also specialise in reducing noise and vibration throughout the exhaust aftertreatment system. Spacer rings are inserted between the inner and outer pipe and help to maintain a constant gap through changes in thermal expansion whilst absorbing and reducing vibration and noise.
