3.2.7.3 Drying Unit
3.2.8 Model 5465 Dry Gas Dehumidification System (Optional)
This system shown in Figure 3.2-6 consists of a solenoid valve with
an attached power cord and pressure regulator plus 6’ (2m) of ¼”
(6mm) OD high-pressure polyflo tubing, terminated with quick
disconnect fittings. The regulator is used to fine tune the gas flow
into the chamber and is in addition to the regulator that is normally
attached to either a user supplied gas tank or a central dry gas or
air supply outlet.
The pressure from the dry gas source must be
limited to 50psi.
The valve assembly is packed separately during
shipping and is installed onto the chamber by the user.

This is a one-way system where gas is injected into the chamber to

left open or be used to vent the nitrogen to prevent pressure build-
up.
