Spray cooling
After the sterilisation phase, the steam in the sterilisation chamber is
replaced by compressed air.
The water introduced when the program is started and then sterilised with
this option is pumped through a heat exchanger to be water-cooled and is
then sprayed through nozzles onto the sterilised items.
Direct softwater spray cooling
After the sterilisation phase, the steam in the sterilisation chamber is
replaced by compressed air.
The on-site demineralised water is sprayed onto the sterilised items
through a booster pump and nozzles.
Closed cooling circuit
Water is fed in a closed circuit via the cooling coil and through a heat
exchanger in order to cool the sterilisation chamber. Otherwise, the
cooling is similar to cooling with and without support air.
3.7.2 Maintenance tasks
Filling the closed cooling circuit
After a repair to a closed cooling circuit, it must be refilled with
unprocessed water after the fault has been fixed (see chapter 2.4.1,
“Testing the water quality”).
The necessary pre-pressure in the system measures 1.5 bar (cold).
