Page 8: Introduction
INTRODUCTION The ECS-SS HF EX2 gas cooler is used in gas analysis to lower the dew point of high flow rates of humid gases to avoid condensation in the analyzer for applications where fast response times are requested. An extremely stable gas dew point avoids water vapor cross sensitivity and volumetric errors. APPLICATION Figure 1shows a typical example of an application for installation of an ECS-SS HF EX2 gas cooler unit. -

Page 10: Description
DESCRIPTION High-output, maintenance-free and self-controlling. Intelligent detailed solutions provide optimum cooling of the sample gas and direct separation of condensate to avoid contamination effects. The new controlled compressor cooling system and the special design of the jet stream heat exchanger guarantee an optimum dew point reduction to a low, stable value. -
Page 11: Function
FUNCTION The especially for gas analysis designed M&C ECS-SS HF EX2 gas cooler is a compressor cooler equipped with status alarm for safe continuous operation. The heat exchanger made of stainless steel works on the principle of Jet-Stream. The construction of the Jet-Stream-heat exchanger ensures a good condensate pre-separation and an optimal drying of the sample gas. -

Only carry out work on live parts, when the area has been proved to be „safe“. W a r n i n g Only carry out work on the protective cover in front of the temperature controller, when the area has been proved to be „safe“. Attention must be paid to the requirements of IEC 364 (DIN VDE 0100) when setting high-power electrical units with nominal voltages of up to 1000 V, together with the associated standards and stipulations. -
Page 15: Start-Up
The power connections are located behind the removable front plate of the cooler housing at terminal X0. The potential free contact outputs of the collective status alarm are to be connected at terminal X3. For the cable bushings through the bottom plate of the cooler housing 2 cable glands 2 x M20 x 1.5, clamping range 6-12 mm are available (see Figure 2). -
Page 16: Closing Down
The status contacts must be connected to the external sample gas pump or to a valve in the sample gas line to protect the entire analysis system by immediately cutting off the gas supply in the event of error messages from the cooler! N o t e CLOSING DOWN The site where the cooler is installed, must also remain frost-free even... -
