Dry Gas Supply (Purge Air); Approvals And Certifications - Ametek 241CE II Operator's Manual

Dry Gas Supply (Purge Air)

A dry atmosphere within the Thermoelectric Cooler (TEC) compartment
is necessary to prevent ice from forming, which can damage the cooler. A
dry atmosphere can be created by connecting the Flame Arrestor Fitting
on the Cooler Housing to a purge gas supply (typically N
supply – such as air – with a water dewpoint temperature less than -40 °C
(-40 °F) and a flow rate less than 15 L/day (0.53 CFD). The purge gas pres-
sure upstream of the Flame Arrestor Fitting cannot exceed atmospheric
pressure by more than 1 PSIG (70 mBAR). (Dry gas supplied by the cus-
tomer/end user.)

Before operating the Model 241CE II Analyzer, a Flame Arrestor Fit-
ting must be installed on the Cooler Housing (to a dry gas supply).
This fitting and an associated Flow Restrictor is supplied by AM-
ETEK. Failure to install a dry gas supply meeting these specifications
voids the warranty of the Peltier Cooler.
