This is accomplished by using a specially designed Peltier cooled manifold
to separate the gas from the water.
The following outline drawing illustrates the drier’s operation.
Mount the Peltier drier to the side of the ENERAC using the two thumbscrews.
Make a tight connection so that the heatsink makes good contact with the
ENERAC case.
The sample consisting of gas and partially condensed water vapor enters the drier
through the “SAMPLE INLET”. It flows through multiple narrow
thermoelectrically cooled passages, where total separation of gas and vapor occurs.
The dried sample makes a 180 degree turn, flowing upwards and goes through an
optional membrane filter exiting through the “SAMPLE OUTLET”. To maintain
proper operation the analyzer should be mounted either in a horizontal or vertical
position.
Check the disposable filter inside the Peltier drier filter holder. Make sure that the
filter is clean and dry. Secure the cover and check that the condensation trap is
also screwed tightly to prevent air leaks.
The condensation trap will probably fill with water after 2 to 4 hours depending on
the fuel used. To empty the condensation trap simply disconnect it from the
manifold by unscrewing it. When replacing it, be careful to seat the O-ring
properly.
