Tubing Without Heat Exchanger Purging (Standard Tubing); Heat Exchanger Connections For Tubing Without Purging; Fig. 33: Standard Tubing: Dcu 1 Active, Solenoid Valve Triggered, No Fa - M&C EC-30C Instruction Manual

8.4 Tubing without heat exchanger purging (standard tubing)

Do not mix up the tube connectors for sample gas inlet and outlet.
The inlet and outlet connectors of the heat exchanger are marked
with arrows.
Note
Make sure that all the connections are sealed adequately.
To ensure free removal of the condensate, the stated diameters for
the condensate removal lines can not be decreased!
The standard version of the EC-30C is equipped with tubing without heat exchanger purg-
ing. This standard tubing includes one solenoid valve (valve 1), to switch between the two
deep-cooling units.
The standard tubing of the EC-30C is shown in the following figure.

Gas IN is the connector of the PCU heat exchanger. The sample gas enters the cooler at
this connection. Gas OUT is the connector at the solenoid valve 1, which sticks out of the
bottom plate of the cooler on the left-hand side. The sample gas leaves the cooler at this
connection.
8.4.1

Heat exchanger connections for tubing without purging

The EC-30C provides six connectors for three heat exchangers, which protrude through
the top panel of the device on the left hand-side. The sample gas enters the cooler at the
sample gas inlet of the PCU heat exchanger.
The sample gas outlet DN 4/6 protrudes through the bottom plate of the cooler close to
the front plate on the left-hand side.
