1.1 Intended use

This unit is intended for industrial use in gas analysis systems.
It's an essential component for conditioning the sample gas to
protect the analysis instrument from residual moisture in the
sample gas.
Sample gas coolers with the option for high-purity oxygen
(suffix -O2) are specially optimised, with regard to the wetted
parts, for use with increased oxygen concentrations. A man-
datory special cleaning of the components is carried out to
minimise organic and inorganic contamination. The manu-
facture of the products under controlled cleanliness condi-
tions ensures compliance with the limits based on EIGA Doc
33/18.
Sample gas coolers with the option for high-purity hydrogen
(suffix -H2) are specially refined using advanced manufactur-
ing measures, in particular to prevent hydrogen-induced com-
ponent damage. In addition, the parts in contact with the me-
dia are subjected to an additional visual inspection to remove
any residual metallic contamination, such as chips and
particles. Finally, a leak test is carried out as standard.
For passing of flammable gases, make sure that the parts car-
rying and/or in contact with the medium are tightly connec-
ted.
Please note the specifications in the data sheet on the specific
intended use, existing material combinations, as well as pres-
sure and temperature limits.

1.2 Overview
The RC 1.1 series was designed specifically for high cooling ca-
pacities and high ambient temperatures.
The RC 1.1 with -H2/-O2 heat exchanger series was specially
developed for use with high-purity hydrogen and oxygen.
The RC 1.2+ series was designed specifically for the require-
ments in so-called automated measuring systems (AMS) ac-
cording to EN 15267-3. The series connection of the heat ex-
changers will cool in two cycles to minimise wash-out effects.
The compressor coolers are distinguished by two types based
on the cooling nests. This classification is reflected in the type
designation. The exact item number of the model defined by
you is determined by the model code in the ordering informa-
tion category.

Additional components which every conditioning system
should feature can optionally be integrated:
• Peristaltic pump for condensate separation
• Filter
• Moisture detector
In addition, we offer different signal outputs:
• Status output
• Analog output, 4...20 mA, incl. status output,
• Modbus RTU digital output, incl. status output
This allows for various configurations of the cooler and its op-
tions. Here the approach is to simplify the creation of a com-
plete system in a cost-efficient way using pre-installed com-
ponents with hoses connected. We also prioritised easy access
to wear parts and consumables.

2 Safety Notes
The device may only be installed by qualified specialist per-
sonnel who are familiar with the safety requirements and as-
sociated risks. In addition, through their professional training,
they possess knowledge of the relevant standards and regula-
tions.
Be sure to observe the safety regulations relevant to the in-
stallation location and the generally accepted rules of techno-
logy. Prevent malfunctions and thereby avoid personal injury
and damage to property.
The operator of the system must ensure that:
• Safety instructions and operating manuals are available
and observed,
• the respective national accident prevention regulations
are observed,
