Connecting the Circulation Plumbing
The circulation plumbing continuously circulates the inert gas atmosphere
from the controlled atmosphere glove box and purifies it by removing oxygen
and moisture. The connections from the 3/4" inlet/outlet compression fittings
must be made to the glove box. Depending on the neoprene lined tubing kit
or stainless steel tubing kit selected, route one line from the inlet of the Gas
Purifier to the outlet of the glove box. Refer to Figures 3-1, 3-2, and 3-8.
Next, route the outlet of the Gas Purifier to the inlet of the glove box. A
continuous tubing loop for Gas Purifier circulation is now established. Be
sure to properly tighten all the 3/4" compression fittings at least 1-1/4
turns past finger tight as leaks will affect Gas Purifier performance. The
orientation of all the compression fittings must be properly set per Figure 3-3.
Should your glove box have 3/8" compression fittings (such as Labconco
polyethylene glove boxes), use the 3/4" to 3/8" adapter kits to route the
circulated air through the neoprene lined hose kit. Refer to Chapter 7 to order
all circulation kits and adapter kits.
Note: The Gas Purifier ships fully regenerated and ready
to use. Keep the isolation valves (manually operated)
closed until ready to use. The isolation valves (Figure 3-4)
must be closed until the glove box inert gas atmosphere is
below 5000 ppm. Opening the isolation valves before the
Gas Purifier and glove box are ready for operation will
cause a loss in oxygen and moisture removal capacity.
