The cooler EC-30C can be mounted near to the gas sample point to avoid costly energy consuming heated sample lines. Due to the extremely stable and low gas dew point, there are no water vapour cross-sensitivity and volumetric errors. Description The M&C gas cooler EC-30C is a two stage combination of compressor and Peltier cooler. The automatic defrost function of the dual deep freezer unit ensures 100 % availability during operation. The micro processor-controlled electronics of the EC-30C in combination with the graphical display, offers a high degree of functionality, convenience in use, and safe operation. The EC-30C is built for 24/7 hours of operating time. The cooling capacity of 130 kJ/h is constant, even under maximum allowed ambient temperature. A capacity reserve compensates parts of the natural ageing process and maximizes the service life of the EC-30C. The pre-cooler unit is equipped with a JetStream heat exchanger. The heat exchanger is cooled down to the constant temperature of +2 °C (35.6 °F) by a separate microprocessor controlled compressor cooling unit. The Jet-Stream heat exchanger in the pre-cooler unit removes a large amount of condensate, this ensures a safe and reliable pre-drying of the sample gas. An additional external vessel to separate the condensate is under normal conditions not necessary. The cooling unit of the pre-cooler dissipates the heat of the Peltier-elements. The dual deep freezer unit is equipped with two modified Jet-Stream heat exchangers. Two separate pairs of Peltier-elements are cooling the heat exchangers down to a constant temperature between -20 °C (~-4 °F) and -30 °C (~-22 °F). The factory setting is -30°C (—22 °F). The EC-30C switches automatically every 3 hours between the two deep freezer units. The deep freezer which is currently not in use, will be defrosted to prevent freezing of the heat exchanger and clogging of the gas lines. The new graphical user interface is icon-based for easy and intuitive navigation. The messages are displayed in form of easy-to-understand icons. Features like time stemps for the alarm message history, periodically self-monitoring and pre-warning messages to inform about upcoming maintenance work ensure a maximum degree of comfort, ease-of-use and safety to the operation of the EC-30C. The smart periodically self-monitoring of the EC-30C, helps to plan upcoming maintenance and service work to prevent unnecessary down time. A configurable mA-output is part of the EC-30C standard version. Three optional peristaltic pumps SR-25.2 for automatic condensate removal can be installed into the unit. An external humidity alarm, and an internal and external sample gas flow alarm can be ordered separately as an option. A fourth optional peristaltic pump can be installed in combination with a second magnetic valve to provide permanently fresh sample gas to the inactive cooling unit. This makes sure that even in systems, where water vapour cross sensitivity exists, there are no visible peaks at switching of the dual deep freezer unit. This also prevents short peaks in the sample gas concentration due to stagnant gas.
