9 DESCRIPTION
The patented M&C gas cooler EC-30(/FD) 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  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 +1°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  and  is cooled
with t
wo 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 the cooler with the module EC-FD
containing additionally three peristaltic pumps SR-25.1 for automatic removal of condensate.
