The catalyst coating on the Filter element effectively lowers the ,,Light Off" temperature
at which soot particles will combust. Therefore it promotes continuous and automatic
regeneration of the soot particles that have been collected within the filter element.
The DPX Catalysed Soot Filter System does not require the use of fuel additives, burners
or additional power sources and has no moving parts.
As the combustion process is dependent upon temperature, we recommend that
wherever possible the vehicle should not be left idling for long periods of time.
If no temperature profile of the vehicle is given, Greentop – CTK rents out a data logging
device to determine the actual exhaust temperature at vehicle duty cycle over a
period of 2 – 5 days. The data logger is easy to install and guarantees that the right filter
is laid out for the application.
The rental cost of the logger is DM 300,00 and will be refunded in case the filter is
ordered.

Installation
Engelhard's DPX Catalytic Soot Filter is designed to be a direct replacement for your
existing silencer. Installation is quick and easy.
The product is supplied complete with temperature and backpressure ports.
It is the responsibility of the operator to measure and record the backpressure of the
system at the time of installation, and follow the cleaning procedure of the filter (as
described below). Failure to do so may void the warranty.
Before testing the back pressure, the engine should be run for a period of time at half
throttle to ensure normal operating temperatures of the vehicle are reached.
Backpressure test should be carried out with a standard manometer at high idle (fuel
cut-off) with no load, i.e. neutral gear. The backpressure should not be higher than 150
millibar. If required a backpressure Kit can be purchased through Engelhard. The kit
comes complete with a backpressure gauge capable of reading up to 250 millibars,
and a snubber valve to eliminate engine pulsation.
After installation, there should be no visible smoke. If smoke is noticed, the operator
should contact the supplier immediately.
