6 Introduction
The portable gas conditioning systems PSS-5C, PSS-5/2C and PSS-5/3C are designed especially for
applications where accurate gas analysis at constantly changing locations is required.
The entire gas conditioning system is housed in a compact and impact-resistant plastic case equipped
with an integrated trolley with extendable handle. This allows gas analysis at various locations to be
carried out quickly, reliably and with low maintenance.
7 Function of the M&C Jet-Stream Heat Exchanger
The ECPX000C gas coolers, specially developed for analysis technology, are designed for maximum
flow rates of up to 350 Nl/h. They are also installed as system assemblies in the PSS-5C, PSS-5/2C
and PSS-5/3C.
Jet-Stream heat exchangers are available in Duran glass, stainless steel (316Ti) and PVDF
(polyvinylidene fluoride). The selection of the appropriate heat exchanger material is customer-
specific. The heat exchangers are easily accessible and easily replaceable in a heat-insulated cooling
block. Figure 4 shows a schematic diagram of the heat exchanger function.

8 Application
The PSS-5C gas conditioning system is suitable for variable discontinuous use as well as for
continuous operation.
The upright, closed PSS-5C case with screwed in connectors complies with protection class IP42 as
required by the EN15267-4:2017 standard. It contains a standard gas temperature monitoring as well
as a temperature display visible from the outside.

11 Description
The PSS-5C gas conditioning system is equipped with the powerful Peltier gas cooler of the new
series as standard.
The cooler is equipped with a jet-stream heat exchanger, which cools the sample gas constantly to
+5 °C [41 °F], independent of the ambient temperature. As soon as the operating temperature
< +8 °C [46.4 °F] is reached after commissioning, the sample gas pump N...KPE is automatically
switched on by the gas cooler status contact. The peristaltic pump SR 25.2-W ensures continuous
condensate removal. This also allows to easily accomplish long-term measurements with the gas
conditioning system. The corresponding particle filtration is carried out by the FP-2T fine filter.
For easy handling of the PSS-5C, the display and function of the cooler are visible from the outside.
The case only needs to be opened for maintenance.
The portable PSS-5C gas conditioning system is a complete conditioning system for most gas
analysis devices. The components installed in the PSS-5C are intended for “continuous use”.
For special measuring tasks, additional or other components from our extensive product range can
also be used.

All components of the gas conditioning system are freely accessible and built into a portable case 2.
The case door 1can be opened to the left by loosening the latches mounted on the side and top of the
case.
The installation of the gas cooler 7and a corresponding diaphragm sample gas pump 5depends on the
required maximum gas volume flow.
The minimum flow rate is determined by the sample gas pump 5. If the required minimum total flow rate
is not reached, excessive overpressure can lead to premature destruction of the pump diaphragm. The
maximum pressure is reduced by using an optional needle valve in the bypass of the sample gas pump
(Part No. 01G9050).
The gas cooler is equipped with a Duran glass heat exchanger 8as standard. Heat exchangers in PVDF
or stainless steel are optionally available.
The FP-2T fine filter (2 µm filter porosity) 4, installed upstream of the sample gas pump 5, ensures the
necessary solids separation.
The overtemperature alarm contact (+8 °C [46.4 °F]) of the cooler automatically regulates the
switching on and off of the sample gas pump 5.
The resulting condensate is continuously discharged by a peristaltic pump type SR25.2-W 6.

The 4/6 mm tube connections for the condensate and sample gas lines are located on the side of the
case.
A stainless steel sample probe (length 0.5 m, Ø 6 mm) and a 3 m PVC sample tube (4/6 mm) are
included in the standard scope of delivery.
The ventilation grids in the door and in the left side wall of the case provide sufficient convex forced
ventilation.
Options:
The PSS-5... sample gas conditioning unit can be equipped at the factory with a maximum of two
sample gas outlets. Each sample gas outlet can be controlled by the optional installation of a flow
meter type FM40 with needle valve according to the specified volume flow range (see the option table
in chapter ‘9 Technical data’).
Unused mounting holes for sample gas outlets or flow meters are closed with blind caps.
I To protect the downstream analyzers against liquid ingress and to increase the operational reliability
of the entire system, we recommend the installation of a liquid alarm sensor type LA1S (Part No.
01G9015). For this purpose, the FP-2T fine filter installed as standard is replaced by the FP-2T-D fine
filter with mounted liquid alarm sensor at the factory. The evaluation electronics for the LA1S liquid
sensor are integrated as standard in the ECPX000C cooler.
The PSS-5... can also be equipped with a special sample gas inlet (Part No. 01G9060) for connecting
a heated line. The existing kink protection can only be used for heated lines with connection type "C"
(Part No. 03B1012). Assembly instructions can be found in chapter “18.1.1 Connecting the heated
sample line with special adapter (option)”.
It is also possible to connect the heated line (Part No. 01B4036) in connection with the gas sampling
probe PSP 4000.
The temperature controller 701 (Part No. 01G9055) which is necessary for the regulation of the heated
line is mounted on the terminal rail 3(Figure 8) at the factory with the required option.
A 3-way ball valve (Part No. 01G9046) or a 5-way ball valve (Part No. 01G9045) can optionally be
installed in the inlet of the gas conditioning unit for test gas feeding or sample gas switching.
