Spark Arresters

Tested and approved to the highest standards

ATEX Certified Products


Western TydensQUALITY APPROVED

Western Tydens Spark Arresters are designed specifically for preventing the risk of fire, due to theignition of flammable materials, caused by spark emission from the exhausts of internal combustionengines.

The risk of fire caused by exhaust sparks is so high that access to many sites is barred unless enginesare fitted with spark arresters, and many countries have legislation to this effect. The risk is greatestwith diesel engines, where carbon can build-up and be ignited. The high ratio of oxygen which ispresent in the exhaust pipe (when the engine goes off load) maintains the ignition of partially burntcarbon particles which are then discharged as highly dangerous sparks.

Efficient DesignWestern Tydens Spark Arresters are designed on the centrifugal principle, which has the effectof spinning the live carbon particles in the exhaust gas at high velocity on the outer casing, andretaining them until they have lost energy, rending them inert before discharge.

Most Western Tydens Spark Arresters can replace an existing silencer. They will maintainsufficient noise attenuation for normal industrial use, with no significant increase in backpressure. Where further noise attenuation is required, the units can be fitted in series with anormal silencer. Alternatively, simple add-on units are available for temporary installation.

Low MaintenanceWestern Tydens spark arresters are of a non blocking design, so carbon build-up will notaffect back pressure. Apart from routine visual safety checks there is usually no need to cleanthem.

ATEX Tested and ApprovedAll Western Tydens Spark Arresters have been stringently tested for their spark arrestingabilities. Both the Primary and Secondary ranges have been independently tested by SIRA toEN1834 and when made from 316 stainless steel comply with the requirements of the EUʼsATEX Directive. Each spark arrester carries an approval plate with the appropriate ATEX andCE markings and is supplied with a Certificate of Conformity. (Special installation requirementsmay be required for different ranges. Please consult us).

Wide RangeWestern Tydens Spark Arresters come in three basic ranges, offering a standard variety ofshapes and sizes for engines up to 500hp (per exhaust bank). We can also design andmanufacture products to directly replace existing silencer/exhaust installations.

Product SizingCorrect unit should be identified from the engine power rating in Horse Power (KW) Measureand specify the correct pipe size to fit the existing exhaust line. In general a larger unit will givea lower back pressure

ConstructionStainless Steel units are from high grade 316 as specified by ATEX. Mild steel units arefinished in heat resistant black paint and have stainless steel internal parts designed as a failsafe to outlast the outer case.

Note:Spark Arresters are a safety device and the use of the correct product and proper installation isimportant and should be treated seriously.

Exhaust Purifiers and Cleaners

Catalytic ConvertersParticulate Filters


Catalytic ConvertersFOR DIESEL ENGINES

Diesel Oxidisation Catalyst (DOC)

Diesel Exhaust Purifiers, from Engine Control Systems, consist of either a ceramic or a metallicprecious metal substrate coated with advanced precious metal catalyst washcoat and are packaged ina stainless steel housing. These purifiers oxidise hazardous exhaust gases, Carbon Monoxide andHydrocarbons to form Carbon Dioxide and Water. The ceramic series also have an effect on reducingparticulate emissions.

Fitting a two way catalytic converter will greatly reduce the toxic effects of diesel exhaust emissionsand the associated health problems caused, and will eliminate the unpleasant smell associated withdiesel exhaust. It is a vital element when using an engine in a confined space.

The temperature of the exhaust gas will determine the effectiveness of the catalyst in reducing the CO and HC. In general catalysts are more efficient at higher exhaust temperatures and should bemounted as close to the engine as possible.

Catalytic Converters

We offer two ranges of catalysts, Ceramic, which offer the best purification over a widertemperature range and a reduction of particulate, or Metallic which are a more ruggedconstruction where vibration and shock maybe an issue. The catalyst should be installedas close to the engine as possible for maximum heat transfer either with an in line unit, oras a muffler replacement.

For optimum performance the correct sized catalyst must be used. For simplification withsizing the engine air intake figure is used, if the engine manufacturers data is not availableuse the following calculation, but note a larger model will provide better pollutant reductionand lower back pressure.

Muffler ConversionsStandard in line units are often unsuitable due to space restrictions, for these applicationscustom designed units are available as direct replacements for existing silencers, send us adrawing or some photos.

We are often able to convert existing silencers to incorporate the DOC. Simply remove theexisting silencer and send it to us and we will either build in the cat or make a new one, thisensures easy trouble free installation.

Engine Intake air flow (m3 / Hr) = Engine displacement (litres) x maximum RPM x C

Where C = 0.03 For normally aspirated enginesC = 0.05 For turbo charged enginesC = 0.06 For turbo charged with aftercooler engines

A new generation filter which sits mid way between a Catalytic Converter (DOC) and aDiesel Particulate Filter. Although not as thorough as a DPF they offer good cleaning withlower price easy installation and simple operation.

The partial flow, comprises a series of wound substrates, similar to those found in aCatalyst, which traps the soot and oxides it due to the catalytic coatings, effectivelyremoving up to 60% of the particulate, and nano particulate matter. It is installed andoperates as a conventional catalyst.

The partial flow filter has the advantage over a wall flow filter in that it offers lower backpressure, 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 existingbox, 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 thecatalytic 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 theextremely small nano (PM10), particles, it also creates local environmental and productcontamination.

DPFʼs are designed to trap and collect this soot, typically 90%+ resulting in very cleanexhaust at the tail pipe. This collected soot is either burn off in various ways, to createCO2, 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 filterwhich traps the soot particles, until full at which stage the element is replaced, typicallyevery 300 hours. Very simple and easy to fit, no changes required to the exhaust systemand will offer an 80%+ efficiency. Will not have any effect on CO and HC toxins. Can beused with any type of diesel.

Consult us for more details.


Particulate FiltersCombifilter Active Regeneration

The Unikat Combifilter is an integrated diesel particulate filter and silencer which typicallyremoves 95%+ of the particulates from the engine exhaust and when combined with acatalyst 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 elementraises the temperature to the point at which the soot burns off. This regeneration processis 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 awall mounted regeneration station consisting of an air pump and electronics for monitoringand creating the regeneration. An alternative exchange system is available consisting of atwo filter arrangement, a clean filter replaces a dirty filter which is regenerated off theequipment.

The Combifilter is a semi porous silicon carbide ceramic block which allows clean gas topass through but traps the soot. An electrical heater raises the temperature above 600degrees during regeneration which effectively burns the soot in the presence of air and itpasses out through the wall as CO2.

The Combifilter is ideal for equipment such as fork lift trucks, can be used with high sulphurdiesel.

Particulate Filters

Passive Regeneration

The Combifilter is available as model type K which has an 8 hour regeneration cycle, ortype S with a 40 minute regeneration cycle, both types use a Silicon Carbide filter block.

Purifilter

Self Regenerating Filters, these use a silicon carbide block as with theCombifilter but with a catalytic coating. At sustained temperatures ofaround 280 degrees the soot trapped in the filter will naturally burn inthe presence of the catalytic coating, into CO2 and be released throughthe wall. The catalytic coating will also reduce the CO and HC.

These filters are intended for permanent installation on vehicles andmachinery which is working constantly under load where high exhausttemperatures are to be found, and should only be used with low sulphurfuels. Consult us for details.

Product SizingFor maximum effect the correct sized filter must be used. For simplification the engine air intakefigure is used, as follows:

Engine Intake air flow (m3 / Hr) = Engine displacement (litres) x maximum RPM x C

Where C = 0.03 For normally aspirated enginesC = 0.05 For turbo charged engines
