1.2 WARM-UP
When the door is closed, if one of the 6 available sterilization cycles is selected and activated, the door is locked and
the WARM-UP phase is activated.
During this phase are warmed up:
- chamber by the chamber heating element;
- generator by the generator heating element;
until reaching the following temperature levels.
- tube bundle heating element > PT3 temperature reading - 110°C;
- generator heating element > PT2 temperature reading - 140°C;
- chamber > PT1 temperature reading - 60°C.
When the above values are reached, the next phase begins. This is the 1st VACUUM PHASE.
The 1st VACUUM PHASE will start after 10 minutes even though the temperature readings are below the values listed
above.
The WARM-UP phase is divided into 2 sections:
- section 1 continues until PT2 temperature reading = 110°C
- section 2 continues until PT2 temperature reading = 140°C
During section 2 of the WARM-UP phase, the following components are turned on:
- vacuum pump
- solenoid valve EV2 (air suction)
- solenoid valve EV4 (vacuum pump bypass)
so that the pump reaches its regular operating conditions and any condensate in the tubes is eliminated.

FUNCTIONING
1.3 1st VACUUM PHASE
This phase marks the beginning of the sterilization cycle proper. As the vacuum pump is activated, the maximum
vacuum level in the chamber, namely – 0.80 bar, can be reached (S 17 Classic -0.75 bar).
The tube bundle heating element of the chamber and the generator heating element remain activated throughout this
phase so the steam generation can be managed properly.
The 1st VACUUM PHASE must ensure that as much air as possible is removed from the chamber. In order to achieve
this, repeated steam shots are injected as pressure drops to aid removal of any remaining air.
These steam shots are operated automatically according to pressure value in the chamber as follows:
- steam shot starts > chamber pressure reading – 0.70
- steam shot ends > chamber pressure reading – 0.60
This sequence is repeated 3 times, and pressure drops until reaching the preset vacuum level of – 0.80 bar. This value
triggers the next phase, namely the 1st PRESSURE RISE.
The control system operates the solenoid valve EV2 (air inlet) when it is needed to improve vacuum pump perfor-
mance, which may be the case during the last pressure drop phase.

1.4 1st PRESSURE RISE
During this phase, steam injection into the chamber is activated to raise pressure back up to 1.00 bar from the negative
value reached during the vacuum pulse.
Pressure is raised in two steps; rstly, from – 0.80 bar to 0.00 bar, and then from 0.00 bar to 1.00 bar.
During the rst pressure rise step, solenoid valve EV2 is activated to compensate for any air pockets which may have
developed in the hydraulic circuit outside the chamber.
The tube bundle heating element of the chamber and the generator heating element remain activated throughout the
pressure rise phase to ensure that the proper temperature is maintained in the chamber and enable fast steam genera-
tion.

After the 1st PRESSURE RISE is completed properly, the sterilization cycle continues as pressure is lowered again to

1.5 2nd VACUUM PHASE
During this phase of the cycle, the pressure in the chamber, which had reached 1.00 bar during the 1st PRESSURE
RISE is lowered by releasing steam through solenoid valve EV1 and the condensate fraction through solenoid valve
EV3, which is connected to the chamber lter.
Upon reaching 0.10 bar, solenoid valve EV4 is activated and has the vacuum pump – which had been activated at the
beginning of the 2nd VACUUM PHASE – lower pressure further to approach – 0.80 bar.
No steam shots occur during this phase.

1.6 2nd PRESSURE RISE
This phase is similar to the 1st PRESSURE RISE, in that pressure rises back up to 1.00 bar from the negative value
reached during the vacuum pulse.
The sequence of vacuum pulses and pressure rise phases eliminates nearly all air left inside the sterilization chamber,
as well as any air contained in any hollow bodies or porous materials included in the load.
Eliminating air ensures optimal steam diffusion and equal temperature at all points of the load.

1.8 3rd PRESSURE RISE / STERILISATION PROCESS
Alternating pressure drops to a vacuum value of – 0.80 bar with two pressure rise phases up to 1.00 bar ensures that
a residual amount of air of 0.06% of total initial air is retained.
After the phases outlined above, a 3rd PRESSURE RISE begins that introduces the STERILIZATION PROCESS prop-
er, which occurs at 134°C/2.15 bar or 121°C/1.10 bar, depending on which type of cycle has been selected.
During this pressure rise phase, the different components are in the same (on/off) states as during the previous phases.

After the pressure and temperature values set for the selected sterilization cycle have been reached, a BALANCING
phase of nearly 15” is activated to stabilize temperature inside the chamber before the PROCESS phase proper begins.
Maximum, normal and minimum pressure values to be observed during the BALANCING and PROCESS phases are
set for each cycle.
Cycle type Pmax Pnorm Pmin
121°C 1.14 1.11 1.08
134°C 2.17 2.14 2.12
During the BALANCING and PROCESS phases, the control system takes the following actions as required:
- it powers on the tube bundle heating element of the chamber to raise value T in the chamber
- it powers on EV1 to discharge steam from the chamber when pressure rises above the allowed Pmax value
- it powers on the water injection pump/EV6 to inject steam into the chamber when pressure drops below the allowed
Pmin value

1.9 DISCHARGE
When the PROCESS phase is completed, the DISCHARGE phase begins. During this phase, all steam is discharged
from the chamber and a vacuum value of - 0.80 bar is reached.
Just like the previous PRESSURE DROPS TO VACUUM phases, the DISCHARGE phase begins with a natural de-
pressurization phase that uses the pressure generated by steam, during which only the drain solenoid valves EV1 and
EV3 are operated.
To achieve complete DISCHARGE, until achieving – 0.80 bar, the system keeps lowering pressure by means of the
vacuum pump and operating the solenoid valve EV4.
Again, the solenoid valve EV2 is activated to balance pressure inside the hydraulic circuit and aid the operation of the
vacuum pump.

After the DISCHARGE phase, the DRYING phase begins. This phase is an integral part of the sterilization cycle.

13
EN
TECHNICAL MANUAL - B CLASSIC / B FUTURA / S CLASSIC
FUNCTIONING
1.10 DRYING
This phase of the sterilization cycle eliminates any moisture left inside the chamber and fully dries the load.
Drying is achieved by maintaining a negative pressure level inside the chamber, so that condensate can evaporate
even at temperatures below 100°C.
The drying phase has a different duration for each sterilization cycle (e.g. 12’ for 134°C universal cycle). During the dry-
ing phase, a series of pressure pulses take place in the chamber, approximately between - 0.80 bar and - 0.40 bar, to
aid total removal of any residual steam; the number of pulses may vary depending on the moisture content in the load.
During the pressure rise phases that take place during these pulses, solenoid valve EV5 is activated to let air ow into
the chamber through the bacteriological lter; this air ow aids steam removal.

When the standard drying time – plus any additional drying time set by user –have elapsed, the VENTILATION phase
begins.

B CLASSIC / B FUTURA / S CLASSIC - TECHNICAL MANUAL
FUNCTIONING
1.11 VENTILATION
During this phase, pressure starts rising again gradually to achieve a balance with ambient pressure.
Pressure is raised by keeping suction in the chamber active through the vacuum pump, while air is admitted to the
chamber through the bacteriological lter/EV5; VENTILATION ends upon reaching a pressure of > -0.30 bar in the
chamber.
