Figure 2 Design of the portable conditioning and sampling system PSS-10/1
All the components of the gas conditioning system can be easily removed from the portable case.
The door of the case can be opened by moving the toggle-type fasteners on the side and the top to
the left.
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:
The minimum amount of flow is determined by the sample gas pump. 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 (see
Appendix for individual component instructions).
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.
The 4/6mm hose connections for the condensate and measuring leads are located on the right-hand
side of the case (see figure 2 and 3).
The stainless steel sample probe (0.5m length, 6mm diameter) and the 3m sample line (DN 4/6mm)
are delivered with all models.
The ventilation grids located in the lid and the left-hand side of the case ensure that the equipment is
sufficiently ventilated.
