Electrical Control Panel
Three-phase AC electric power at 460/480 60 Hz or 380/400 50 Hz 50A is supplied to the drive
motor and exhaust fan motor by the electrical control panel. In addition to the START and STOP
switches that turn the machine on and off, the control panel contains a DC power supply, control
relay, power contactor, starter, and other electrical components. A thermal overload in the starter
shuts down the degasser in case of excessive current draw. Upon sensing an overload, power is
immediately interrupted to both the degasser drive motor and exhaust fan motor.
Vent Pipe
Aided by the exhaust fan, liberated gas flows upward through the vent pipe and exits the flange at
the top of the vent. Slots around the outside of the vent pipe permit entry of ambient air to mix
with the gas and facilitate gas extraction.
