5 TERMINOLOGY AND SYMBOLS USED
14.1a ME Gas sampling and gas conditioning technology 7
6 INTRODUCTION
The gas conditioning CSS-VC unit, either for 19 "- or wall mounting or as a portable unit in carrying
case, is a fully pre-assembled compact continuously-operating gas purification system, which,
depending on the design, can supply a sample gas volume of max. 1 x 250Nl/h (CSS VC1) or 2 x
150Nl/h (CSS-VC2). Sample gas conditioning units are suitable due to their equipment and additional
options for the wide-ranging requirements of continuous gas analysis.
The entire gas conditioning unit is housed in a compact, rugged steel housing so that gas analyses
can be performed rapidly without a great deal of effort, with low maintenance and reliability.
Gas conditioning unit CSS-VC must not be used to support gas/air or gas/oxygen mixtures that are
ignitable during operation, for the supply of combustible gases that can form an ignitable mixture in
combination with air or oxygen, or in potentially explosive atmospheres and in potentially explosive
locations.
8 Gas sampling and gas conditioning technology 14.1a-ME
7 APPLICATION
With the CSS-VC, fully pre-installed gas conditioning systems are created for continuous use, which
can be integrated perfectly into analytical systems. The compact design makes few demands on
space. The gas conditioning systems are operational within minutes. This renders time-consuming and
expensive procurement of individual components and small parts and their assembly unnecessary. A
portable version is also available in a carrying case.

All components of the gas conditioning systems are installed in a strong compact steel housing for wall
or 19" mount. The ventilation grilles in the side walls provide adequate forced ventilation.
Filter, flow meter and peristaltic pumps are located in the front panel and thus ensure very simple
maintenance. Due to a removable lid and a hinged front panel, quick and easy inspection and
maintenance of all other built-in components is possible, in particular the easy changing of heat
exchangers.
The compressor gas cooler can be equipped with one or two heat exchangers made of glass, stainless steel or PVDF.
Peristaltic pumps of type SR25.2 are used for continuous condensate removal or as a metering pump.

NOTICE!
Storage of the gas conditioning unit should be in a sheltered frost-free
room!
The current cooler temperature is displayed on the multi-functional control unit TCU mounted on the
front panel. The setpoint temperature of the cooler can be set by pressing keys. In the event of
warnings or faults, plain text information appears on the display and is also indicated by LEDs (e.g.
cooler within the setpoint range and no other alarms - green LED, flow alarm (option) - yellow LED,
temperature ± 3° C from the setpoint and humidity alarm (option) - red LED).
The fine filter downstream of the cooler (different filter types available) provides for the necessary
separation of solids. The condition of the filter can be judged from the outside. To protect the
downstream analysers against liquid penetration and to increase the operating reliability of the whole
system, according to the selected filter type, a suitable liquid alarm is possible or already integrated
into the filter.
A group alarm or on request individual alarms including mA output for the cooler temperature at the
output terminals is available wired. Via potential-free contacts for the group alarm or the individual
alarms (cooler temperature, flow, fluid in the system), an alarm message and shutdown of the sample
gas pump, if present, occurs.
Integrated sample gas pumps are available in three performance levels to choose from N3/5/9 KPE.
The flow meter FM40 arranged in the sample gas outlet with a measuring range adapted to the pump
power can be supplied for flow monitoring with a flow sensor FA-20mo. In addition, each sample gas
line can be equipped with a second sample gas outlet or bypass flow meter and flow control.
In the event of an aerosol problem, a liquid particulate filter CLF can be added downstream of the flow
meter in the sample gas outlet.
Via expansion modules for the control unit TCU two further temperature controllers are available e.g.
to regulate heated lines or gas probes. Here too external sample gas pumps can be connected and
individual sample gas probes can be backflushed.

NOTICE!
So that the unit is safe and operates reliably, it should be mounted
horizontally and without vibration. Only then is proper separation and
drainage of the condensate in the heat exchanger of the cooler
ensured.
The mounting of the gas conditioning unit should take place away from
heat sources and be freely ventilated so that there can be no disruptive
accumulation of heat.
When installed outdoors, adequate protection against direct sunlight
and moisture needs to be ensured. In winter, the place of installation
must be frost-free; ensure correct protection for the device.
Temperature variations, strong air movement and aggressive
atmospheres at the place of installation are to be avoided.
To ensure safe operation of the gas conditioning unit and downstream
analysers and to avoid false alarms, the gas conditioning unit should
not be used outside the specified temperature range. It must also be
protected against the ingress and accumulation of dust.
Downstream analysers and lines must operate at temperatures
significantly above the specified gas outlet dew point of +5 ° C. This
will avoid subsequent condensation of the gas in the connecting lines
to the analysers.
Unheated gas sample lines must be laid on a slope to the cooler.
11 INSTALLATION INSTRUCTIONS
11.1 CONVERSION TO WALL MOUNTED OR 19" RACK HOUSING
Gas conditioning units CSS-VC.., if not in a carrying case, are delivered with wall-mounting or 19"
housing.
Depending on which housing is required, the gas conditioning unit can be converted very simply by
moving the mounting bracket:
Remove two screws per bracket
Align bracket to the mounting holes according to the desired housing forward or rearward
Secure the bracket flush with the housing panel (19" mounting) or with protrusion to the rear
(wall mounting) with the two fixing screws on the housing
