4.2 Principle

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 graphi-
cal 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 aging process and maximizes the
service life of the EC-30C.
The pre-cooler unit is equipped with a Jet-Stream 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 conden-
sate, 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).
