1 Introduction
This quick guide will assist you in starting up the unit. Follow
the safety notices or injury to health or property damage may
occur. Carefully read the original operating instructions in-
cluding information on maintenance and troubleshooting
prior to startup. These are located on the included CD and on-
line at

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 optimised especially for use with increased
oxygen concentrations with regard to the parts in contact
with the medium. Special cleaning of the components to min-
imise organic and inorganic contamination is mandatory.
Manufacturing the products under controlled cleanliness con-
ditions ensures compliance with the limit values in accord-
ance with 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.
1.3 Scope of delivery
• Cooler
• Product documentation
• Connection-/mounting accessories (optional)
2 Safety Notes
The equipment must be installed by a professional familiar
with the safety requirements and risks.
Be sure to observe the safety regulations and generally applic-
able rules of technology relevant for the installation site. Pre-
vent malfunctions and avoid personal injuries and property
damage.
The operator of the system must ensure:
• Safety notices and operating instructions are available
and observed,
• The respective national accident prevention regulations
are observed,
• The permissible data and operational conditions are
maintained,
• Safety guards are used and mandatory maintenance is
performed,
• Legal regulations are observed during disposal,
• compliance with national installation regulations.
• the device is protected from mechanical loads.
