The explosion proof protection for both models is: 230 V / 115 V: II 3G Ex nA nC IIC T4 Gc (Type Examination Certificate Number: BVS 16 ATEX E 055 X) Certification was carried out by DEKRA EXAM BBG Prüf- und Zertifizier GmbH. -
Page 10: Information And Safety Instructions For Using The Cooler
Information and safety instructions for using the cooler Inhalation hazard possible, if using toxic or asphyxiant gases! Warning Purge cooler with inert gas or air before opening! If the cooler is used for toxic gas or asphyxiant (oxygen-displacing) gas, it needs to be purged with inert gas or air before opening. -
Page 11: Introduction
Introduction The M&C ECM-EX2 gas cooler unit is designed to operate whenever there is moisture interference in the sample gas. Lowering the sample gas temperature to a very low and stable dew point prevents condensate built-up in the analyzer and avoids unstable measurements, because of water vapour cross-sensitivity or volumetric errors. The ECM-EX2 is certified for appropriate use in the specified Ex zones noted in the Type Examination Certificate. -

Page 15: Description
Description Figure 2 shows the ECM-EX2-2 cooler unit Figure 2 ECM-EX2-2 The cooler ECM-EX2 is also suitable for wall mounting. The depth of the cooler housing is 270 mm [≈ 10.63"] without, and 316 mm [≈ 12.44"] with optionally mounted peristaltic pumps. The cooler ECM-EX2 is conform to the system protection IP20 (EN 60529). -
Page 16: Function
Function The M&C gas cooler type ECM-EX2 is a compressor cooler equipped with a status alarm for safe and continuous operation. Up to 2 Jet-stream heat exchangers made of Borosilicate glass, PVDF or stainless steel are located in a heat-insulated cooling block, where they are easy to access and to remove. -
Page 17: Receiving And Storing Of The Device
Receiving and storing of the device The ECM-EX2 gas cooler is a complete pre-installed unit. • Please remove the ECM-EX2 carefully from the packaging. Check the scope of the delivery specified on the delivery note. Please make sure that you have received all items stated on the delivery note. •... -
Page 18: Mounting
Mounting Do not mount or carry out any work at the gas cooler while potentially explosive atmosphere is present. The process and the environment of the cooler needs to be explosion-free (explosion- free zone) during mounting. A zone is declared as explosion-free zone, if it is free of explosive atmosphere. - Page 19 • The sealing rings should be installed with the PTFE side facing the medium. PVDF- resp. stainless steel heat exchangers with G 1/4" female resp. G 3/8" female • The fitting tubing or hose couplings with threaded connections have to be screwed in with PTFE thread sealing tape.
