Description
Heat Dissipation
To allow for heat dissipation and servicing, the required minimum
clearances are:
- 150 mm (6") each side
- 75 mm (3") top and bottom
- 900 mm (36") front
Door Swing
To allow for full door swing, minimum clearance in front of the
analyzer is approximately 574 mm (22.6").
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 N2) or to a dry gas 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 pressure upstream of
the Flame Arrestor Fitting cannot exceed atmospheric pressure by
more than 1 PSIG (70 mBAR). (Dry gas supplied by the customer/
end user.)
Caution:
Before operating the 241CE II Analyzer, a Flame Arrestor
Fitting must be installed on the Cooler Housing (to a dry
gas supply). This fitting and an associated Flow Restrictor
is supplied by AMETEK. Failure to install a dry gas supply
meeting these specifications voids the warranty of the Peltier
Cooler.
