Frame and Chassis
The base and chassis are the main support structure of the sterilizer and
provide the means to move and support the sterilizer. The base frame
provides mounting locations for exterior panels.
Access Panel
The base module is covered by one access panel: the front bottom panel.
It is attached to the chassis by two screws.
Circuit Breaker
A magnetic-hydraulic automatic circuit breaker/switch is mounted on the
right side of the front bottom panel. The circuit breaker/switch is used to
turn power on and off and will trip open to protect the sterilizer if a
current overload occurs.
LFPS II Power Supply
The low frequency plasma system (LFPS II) power supply provides
electrical energy to generate plasma in the chamber. The LFPS II output
is connected to the feedthrough and electrode by a twin axial cable. A
control cable connects the LFPS II to the system controller.
Printer
The thermal printer produces a paper record of cycle information
including process parameters, warning and error messages,
troubleshooting information, machine and cycle identification
information, and validation signature locations for the operator’s
confirmations.
The printer assembly is mounted on the front right side of the base
module. Access to the printer paper roll is provided by a flip-open door.
Vacuum Pump Assembly
The vacuum pump assembly consists of a vacuum pump, exhaust oil mist
filter, exhaust catalytic converter, oil return valve, vacuum control valve
and related components. The vacuum pump assembly is mounted on a
slide-out platform on the left side of the base module.
