Western Tydens QUALITY APPROVED Western Tydens Spark Arresters are designed specifically for preventing the risk of fire, due to the ignition of flammable materials, caused by spark emission from the exhausts of internal combustion engines. The risk of fire caused by exhaust sparks is so high that access to many sites is barred unless engines are fitted with spark arresters, and many countries have legislation to this effect. The risk is greatest with diesel engines, where carbon can build-up and be ignited. The high ratio of oxygen which is present in the exhaust pipe (when the engine goes off load) maintains the ignition of partially burnt carbon particles which are then discharged as highly dangerous sparks. Efficient Design Western Tydens Spark Arresters are designed on the centrifugal principle, which has the effect of spinning the live carbon particles in the exhaust gas at high velocity on the outer casing, and retaining them until they have lost energy, rending them inert before discharge. Most Western Tydens Spark Arresters can replace an existing silencer. They will maintain sufficient noise attenuation for normal industrial use, with no significant increase in back pressure. Where further noise attenuation is required, the units can be fitted in series with a normal silencer. Alternatively, simple add-on units are available for temporary installation. Low Maintenance Western Tydens spark arresters are of a non blocking design, so carbon build-up will not affect back pressure. Apart from routine visual safety checks there is usually no need to clean them. ATEX Tested and Approved All Western Tydens Spark Arresters have been stringently tested for their spark arresting abilities. Both the Primary and Secondary ranges have been independently tested by SIRA to EN1834 and when made from 316 stainless steel comply with the requirements of the EUʼs ATEX Directive. Each spark arrester carries an approval plate with the appropriate ATEX and CE markings and is supplied with a Certificate of Conformity. (Special installation requirements may be required for different ranges. Please consult us). Wide Range Western Tydens Spark Arresters come in three basic ranges, offering a standard variety of shapes and sizes for engines up to 500hp (per exhaust bank). We can also design and manufacture products to directly replace existing silencer/exhaust installations. Product Sizing Correct unit should be identified from the engine power rating in Horse Power (KW) Measure and specify the correct pipe size to fit the existing exhaust line. In general a larger unit will give a lower back pressure Construction Stainless Steel units are from high grade 316 as specified by ATEX. Mild steel units are finished in heat resistant black paint and have stainless steel internal parts designed as a fail safe to outlast the outer case. Note: Spark Arresters are a safety device and the use of the correct product and proper installation is important and should be treated seriously.

Catalytic Converters FOR DIESEL ENGINES Diesel Oxidisation Catalyst (DOC) Diesel Exhaust Purifiers, from Engine Control Systems, consist of either a ceramic or a metallic precious metal substrate coated with advanced precious metal catalyst washcoat and are packaged in a stainless steel housing. These purifiers oxidise hazardous exhaust gases, Carbon Monoxide and Hydrocarbons to form Carbon Dioxide and Water. The ceramic series also have an effect on reducing particulate emissions. Fitting a two way catalytic converter will greatly reduce the toxic effects of diesel exhaust emissions and the associated health problems caused, and will eliminate the unpleasant smell associated with diesel exhaust. It is a vital element when using an engine in a confined space. % level 100 80 60 40 Typical Reduction in Polutants when (Ceramic) Catalyst is fitted. 20 With Purifier 0 Without Purifier CO HO Particulate The temperature of the exhaust gas will determine the effectiveness of the catalyst in reducing the CO and HC.

Catalytic Converters We offer two ranges of catalysts, Ceramic, which offer the best purification over a wider temperature range and a reduction of particulate, or Metallic which are a more rugged construction where vibration and shock maybe an issue. The catalyst should be installed as close to the engine as possible for maximum heat transfer either with an in line unit, or as a muffler replacement. For optimum performance the correct sized catalyst must be used. For simplification with sizing the engine air intake figure is used, if the engine manufacturers data is not available use the following calculation, but note a larger model will provide better pollutant reduction and lower back pressure. Engine Intake air flow (m3 / Hr) = Engine displacement (litres) x maximum RPM x C Where C = 0.03 For normally aspirated engines C = 0.05 For turbo charged engines C = 0.06 For turbo charged with aftercooler engines Muffler Conversions Standard in line units are often unsuitable due to space restrictions, for these applications custom designed units are available as direct replacements for existing silencers, send us a drawing or some photos. We are often able to convert existing silencers to incorporate the DOC. Simply remove the existing silencer and send it to us and we will either build in the cat or make a new one, this ensures easy trouble free installation. If you would like to discuss your requirements in details prior to ordering one of our products or would like technical advice then please do not hesitate to contact us.

Partial Flow Filters A new generation filter which sits mid way between a Catalytic Converter (DOC) and a Diesel Particulate Filter. Although not as thorough as a DPF they offer good cleaning with lower price easy installation and simple operation. The partial flow, comprises a series of wound substrates, similar to those found in a Catalyst, which traps the soot and oxides it due to the catalytic coatings, effectively removing up to 60% of the particulate, and nano particulate matter. It is installed and operates as a conventional catalyst. The partial flow filter has the advantage over a wall flow filter in that it offers lower back pressure, cannot clog and is non-blocking, it is maintenance free. The substrate is usually built into the silencer and so is a direct replacement for the existing box, thus ensuring easy installation. Reduction rates of CO (90%+) HC-odours (90%+) Particulate (40-60%).

Diesel Particulate Filters (DPF) In addition to the toxic gases in the exhaust stream (eg.co) which are removed via the catalytic converter, diesel exhaust contains a large amount of Carbon Particulate or soot, usually seen as black soot. Not only is this harmful to human health especially the extremely small nano (PM10), particles, it also creates local environmental and product contamination. DPFʼs are designed to trap and collect this soot, typically 90%+ resulting in very clean exhaust at the tail pipe. This collected soot is either burn off in various ways, to create CO2, or physically disposed of. Physical Filtration, Replacement Element type D80 type Ideal for light duty and temporary use over short periods. They have a ceramic fibre filter which traps the soot particles, until full at which stage the element is replaced, typically every 300 hours. Very simple and easy to fit, no changes required to the exhaust system and will offer an 80%+ efficiency. Will not have any effect on CO and HC toxins. Can be used with any type of diesel.

Particulate Filters Combifilter Active Regeneration The Unikat Combifilter is an integrated diesel particulate filter and silencer which typically removes 95%+ of the particulates from the engine exhaust and when combined with a catalyst will meet the most stringent requirement. The soot is stored in the filter until full, the equipment is then plugged into an electrical source where the internal heating element raises the temperature to the point at which the soot burns off. This regeneration process is typically done on a daily basis and can take either one hour or overnight. The standard system consists of the Combifilter which is installed on the equipment and a wall mounted regeneration station consisting of an air pump and electronics for monitoring and creating the regeneration. An alternative exchange system is available consisting of a two filter arrangement, a clean filter replaces a dirty filter which is regenerated off the equipment. The Combifilter is a semi porous silicon carbide ceramic block which allows clean gas to pass through but traps the soot. An electrical heater raises the temperature above 600 degrees during regeneration which effectively burns the soot in the presence of air and it passes out through the wall as CO2. The Combifilter is ideal for equipment such as fork lift trucks, can be used with high sulphur diesel. Layout and sizes as shown. Consult us for more details or advice.

At sustained temperatures of around 280 degrees the soot trapped in the filter will naturally burn in the presence of the catalytic coating, into CO2 and be released through the wall. The catalytic coating will also reduce the CO and HC. These filters are intended for permanent installation on vehicles and machinery which is working constantly under load where high exhaust temperatures are to be found, and should only be used with low sulphur fuels.
