INTRODUCTION
European standard EN 285 (Australia/New Zeeland, Standard AS 1410)
specifies the use of fixed programs only. However, the control equip-
ment of HS 66-autoclaves allows the programs to be made variable dur-
ing the time testing is in progress.
As not only the processes but door operation too are controlled automat-
ically, the step to full automation of the handling of sterile items is not
a long one. The control unit is therefore prepared for controlling an
autoclave having a GETINGE ASF automatic loading and unloading
unit.
As with other GETINGE double-jacketed autoclaves, the external sur-
face of the chamber is more than half covered by all-welded U-sec-
tions.. These stiffen the flat walls of the pressure vessel, and at the same
time accommodate the steam which keeps the chamber walls warm in
order to minimize condensation in the chamber. The design principle
makes all welds accessible for visual inspection after the thermal insu-
lation has been removed.
A vacuum pump of the water-ring type removes air, steam and conden-
sation from the chamber and door-gasket groove. The sealing water of
the pump is taken from an open tank which in some cases also supplies
the feedwater pump, on autoclaves with a steam generator, with water.
The condenser between the chamber and vacuum pump converts waste
steam to water. This reduction of the pump handling volume contributes
greatly to improving pump efficiency and protecting the pump and
waste pipes against high temperatures.
A well-damped discharge system after the vacuum pump and well-
dimensioned thermal insulation around the chamber mean that the auto-
clave affects the surroundings to an insignificant extent and is therefore
easy to position.
HS 66-autoclaves have to be supplied with electricity, cold water, com-
pressed air and steam. When steam is supplied from a central steam-pro-
ducing plant, its distribution system is required to be correctly pressure-
reduced, protected by a safety valve and produce a quality of steam
which is suitable in the context of sterilization. (For some versions the
pressure reducer is already fitted)
If the steam is not suitable in the context of sterilization, a steam gener-
ator can be installed inside the trim plates on all models. The task of the
