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.
