6 INTRODUCTION
The gas conditioning units CSS-V1 and CSS-V2, optionally for 19" or wall mounting, are complete preassembled compact continuously operating gas conditioning systems, which, depending on the version,
can deliver a sample gas quantity of max. 2 x 150 Nl/h or 1 x 250 Nl/h. Due to a large number of
additional options, the sample gas preparation can be adapted to the various requirements of continuous
gas analysis technology.
The entire gas conditioning system is housed in a compact and robust sheet steel housing so that gas
analyses can be carried out quickly, with low maintenance and reliably without any major assembly
work.
The CSS-V1 and CSS-V2 gas conditioning units must not be used for sampling flammable gas/air or
gas/oxygen mixtures, for sampling flammable gas which can form an flammable mixture in combination
with air or oxygen, or in explosive atmospheres or in hazardous areas.
10 CSS-V | 1.01.02 www.mc-techgroup.com
7 APPLICATION
The CSS-V1 and CSS-V2 are completely pre-installed sample gas conditioning systems for
continuous use, which can be excellently integrated into analytical systems due to their individual
configurability. The compact design only requires a small amount of space. The preparations are
ready for operation within a few minutes. The usual time-consuming procurement of individual
components and small parts and their assembly is no longer necessary.
