TC-Standard (+) X2
1 Introduction
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.
This device may be operated in a zone 2, explosion class IIC (ATEX & IECEx), explosive gas atmosphere which is rarely and only
temporarily explosive and in Class I, Division 2 (US & Canada).
Optional mounting of various add-on units may limit the area of application of this device.
Cooler with certificate Canada and IECEx
The equipment shall be mounted within a tool-secured IP54 enclosure.
Cooler with certificate USA
The equipment shall be mounted within a tool-secured IP54 enclosure which is capable of accepting one or more of the
Class I Division 2 wiring methods per the National Electric Code (ANSI/NFPA 70).
Cooler with certificate ATEX
The equipment shall be mounted within a IP54 enclosure in accordance with EN 60079-15, and in a tool-secured enclosure which
meets the requirements of EN 60079-0 and EN 60079-15.
Please note the specifications in the data sheet on the specific intended use, existing material combinations, as well as pressure
and temperature limits.
1.2 Overview
The TC-Standard X2 series was designed specifically for high cooling capacities and high ambient temperatures.
The TC-S X2 series was designed specifically for the requirements in so-called automated measuring systems (AMS) ac-
cording to EN 15267-3. The series connection of the heat exchangers will cool in two cycles to minimise wash out effects.
The Peltier cooler is distinguished by two types according to cooling capacity or operation temperature. This classification is re-
flected in the type designation. The exact item number of the model defined by you is determined by the model code in the cat-
egory ordering information.

Additional components which every conditioning system should feature can optionally be integrated:
– Peristaltic pump for condensate separation,
– Filter,
– Moisture detector.
This allows for various configurations of cooler and options. Here the approach is to simplify creating a complete system in a
cost-efficient way through pre-installed components with hoses connected. We further paid attention to easy access to wear
parts and consumables.
