1.0 Introduction
This manual provides information on installing and operating your Terra ErgoHeight™ Work Station.
By studying this document carefully, you can be assured of a long, efficient service life from your system.
2.0 Description
The Humex 2™ Humidifier provides inline humidification of nitrogen or other process gas being fed into a glove box or
similar enclosure.
During operation, a 20W resistance heater inside the Humex 2 vaporizes incoming water fed into a stainless steel
chamber. Process gas, which enters the Humex 2 through separate .25"-diameter flexible tubing, is humidified as it
passes through this chamber on its way to a glove box or other enclosure.
The Humex 2™ humidity sensor, installed inside the remote enclosure, monitors the relative humidity level. As soon
as the %RH falls below a user-selected threshold, a relay inside the Humex activates the heater and a solenoid that
turns on the water flow. When the %RH set point is attained, the Humex turns off heater and water flow.
Operation with the Dual Purge
For optimal efficiency—and to conserve nitrogen— the
Humex can be operated with Terra’s Dual Purge™
Variable Purge Controller.
In this configuration the Humex issues a signal to the
Dual Purge, via a 4-connector low-voltage cable, to
initiate high flow (bypassing the Dual Purge flowmeter)
whenever the humidity falls below the set point. This
high flow of process gas quickly humidifies the
enclosure.
