Embracing Challenge [ IVteC®] Ultra Low Gas Cooler Series ECVersion EC-30 dew-point -30 °C, 250 Nl/hr sample flow rate Special Features ■ Jet-Stream heat exchangers . Dew Point -30 °C ■ 250 Nl/hr sample gas flow rate ■ Continuous operation ■ Low maintenance ■ Self-monitoring incl. status alarm ■ Optimum reliability ■ 19" Rack- or wall mounting housing Application The patented M&C Ultra-Low Cooler EC-30 finds its applications in the analytical field for reducing the dew point of humid sample gases, providing a stable and very low dew point and reducing aerosol formation in the analyser. By mounting the cooler EC-30 near to the sample point, costly energy consuming heated sample lines can be avoided. An extremely stable and low gas dew point avoids water vapour cross-sensitivity and volumetric errors. Description The patented M&C gas cooler EC-30 is a two stage combination of compressor and Peltier cooler with status alarm and automatic defrosting of the dual deep freezer unit for 100% sample availability. The pre-cooler "3" of the gas cooler EC- is fitted with a "Jet-Stream" heat exchanger EC-G which is cooled by a compressor cooling unit with electronic control at a constant temperature of +2 °C. Optimum cooling of sample gases and pre-elemination of a larger part of the condensate from the gas is reliably achieved. No external pre-draining is normally needed. The deep freezer "1" and "2" is cooled with two modified "Jet-Stream" heat exchangers EC-30 fitted between two automatic cooling units for a minimum temperature of -30 °C. The special design of the Jet-Stream heat exchanger guarantees optimum dew point reduction to a low, stable value and secures condensate separation. The gas outlets of the heat exchangers are connected to a 3/2 way solenoid valve. An electronic control system EC-30 switches the solenoid valve for simultaneous changeover and automatic defrosting of the heat exchangers EC-30. In order to guarantee the necessary and minimum operation of the gas cooler EC-30, we provide this unit with an accessory module EC-F containing two fans for forced air ventilation and cooling of the compressor unit. Alternative we deliver an the cooler with the module EC-FD containing additionally three peristaltic pumps SR-25.1 for automatic removal of condensate.
