2.2 Main features
The vacuum pump ensures an optimal sterilisation process in
which the steam interacts properly with the load being processed,
including any cavities.

2.2.2 Test programs
- Vacuum test:
checks the ability to hold a vacuum
- Bowie & Dick test:
checks steam penetration into porous loads
- 121 or 134°C Helix test:
checks steam penetration into hollow
loads
The autoclave is available with the following storage devices:
- USB port (USB peripheral not supplied).
- RS-232 port (for DÜRR DENTAL printer, NOT supplied).
2.2.3 Water filling systems
Automatic:
with the aid of a pump inside the autoclave.
Mains connection
possibility of connecting a demineralisation
system, to increase autonomy. It must be installed by an authorised
technician.
Manual:
as an alternative, the device is equipped with a manual
emergency illing system at the FRONT
(9 fig. 1).
2.2.4 Automatic sterilisation parameter control
During sterilisation, the pressure, temperature and time are
continuously monitored by an automatic process control system.
2.2.5 Motorised closure
The autoclave has a motorised closure system to ensu-
re a good seal. It is based on a screw and nut screw. Closure
works with a pre-locking mode that activates when the door is shut.
The door is only closed fully when the cycle starts.
2.2.6 Bio-X filter
This injects sterile air into the chamber during the drying and
pressure balancing phases.
2.2.7 USB port
This port can be used by medical staff for data download.
2.2.8 Serial port - RS232
This port is only for connecting the DÜRR DENTAL printer.
Use the dedicated serial cable supplied with the DÜRR DENTAL
printer.
2.2.9 Touch screen display
This manages the autoclave fully through a menu system.
2.2.10 LAN connection
This port is only for connecting a LAN.
2.2.11 Safety devices
The steriliser is equipped with the following safety devices:
- Mains fuses
These protect the equipment from faults in the heating elements by
disconnecting the electric power supply.
- Electronic circuit protection fuses
These prevent faults in the transformer primary circuit and low-
voltage loads by disconnecting one or more low-voltage circuits.
- Safety valve
This prevents any overpressure in the sterilisation chamber by
releasing steam to restore a safe pressure. It opens at a pressure
of 350kPa (±10%).
- Steam generator thermal switch
This stops the steam generator from overheating by disconnecting
its electrical power supply. It trips at a temperature of 220°C ±7°C.
- Chamber thermal switch
This protects the pressure vessel heating element from overheating
by disconnecting its electric power supply. It trips at a temperature
of 150°C ±4°C.
- Door lock mechanism safety microswitch
This provides feedback when the door and the door lock system
are not in the correct position or when the door lock mechanism is
not working correctly.
- Pressure switch
This prevents the door from being opened accidentally during the
program when the machine is pressurised (even in the event of a
blackout).
- Overflow system
This prevents water from lowing out onto live parts if the level sen-
sor does not work by draining excess water to the outside.
- Built-in sterilisation process assessment system
This uses a microprocessor to continuously monitor the sterilisation
process parameters. In the event of a fault, it immediately stops the
program and generates alarms.
- Steriliser operation monitoring
When the machine is powered, this monitors all of its important
parameters in real time. In the event of a fault, it generates alarm
