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.
The device is suitable for use in explosive areas Zone 1 (EPL Gb) and Zone 2 (EPL Gc), explosion groups IIA, IIB and IIC, as well as
temperature classes T1, T2, T3 and T4.
The permissible ambient temperature range is -20 °C ≤ T
amb
≤ 45 °C.
Markings on the sample gas cooler include ignition protection types Ex pxb eb mb q [ia] IIC T4 Gb. The erection specifications
