Figure 2 Design of the conditioning and sampling system SS-5 and SS-5/3
The installation of a gas cooler  and an appropriate diaphragm gas pump  will be carried out
according to the maximum flow of gas extracted (see instruction manual for individual components).
The possible combinations are listed in the following table:
SS-5... Type of
cooler
max. gas flow [Nl/h] Sample gas pump
SS-5 ECP1000 150 N 3 KPE
SS-5/3 ECP3000 350 N 9 KPE
The minimum amount of flow is determined by the sample gas pump (see 8.). Premature damage can
be caused to the pump membrane if less than the minimal total amount of flow is extracted as a result
of excess pressure.
All gas coolers are equipped with a Duran glass heat exchanger . Heat exchangers of PVDF or
stainless steel are also available.
The preliminary filter FP-2T (2µm filter element fineness)  installed in front of the gas measuring
pump ensures that the correct amount of solid matter is precipitated.
The sample gas pump  is turned off and on automatically by means of an excess temperature
contact on the cooler (+8°C).
The resulting condensation is continually lead off by means of the SR25.1  peristaltic pump.
A preliminary filter, PF2  has been fitted in the condensation hose in between the heat exchanger
and peristaltic pump. This prevents particles in the condensate entering the pump.
