1. GENERAL INFORMATION
1.1 Introduction
This autoclave is designed to cover a large field of applications for hospitals and medical
centers as well as pharmaceutical and biotechnological industries.
The autoclave operates with saturated steam as the sterilizing agent, and has a
temperature range of up to 137

C (279
º
F) and pressure up to 2.3 bar (34 psi).
The autoclave is equipped with a 36 kW built-in steam generator. This steam generator
acts as a standby if building steam is not available for the sterilization process.
The autoclave is built to receive two steam supply sources, namely from the building, or
from an internal built in steam generator. There is a selector switch on the Front Panel to
choose the source. Before selecting the external generator, check the generator is
connected to the electrical supply and working properly.
The autoclave is equipped with two vertical sliding doors. Each door is operated by two
hydro-pneumatic cylinders mounted laterally on both sides of the door. Each cylinder
contains an integrated and separated oil system. The operation of the cylinders is
performed by air pressure and the oil system acts as a speed control system. An
adjustable restrictor controls the flow of oil from one side to the other side on each
cylinder, controlling the speed movement of the door. (For servicing of the unit see the
SERVICING INSTRUCTIONS chapter.)
The autoclave is mounted through a recessed wall. The two doors are located in two
separate rooms.
The front door, on the side of the master control panel is in the preparation area, from
where the autoclave is operated and serves for loading the material into the sterilization
chamber. This area is known as the "dirty side." The rear door is located on the "clean
side" and serves for unloading the sterilized material from the autoclave. This side of
autoclave is equipped with secondary control panel (slave).
The sealing of the chamber is achieved through a heat resistant silicone gasket, located
in a groove around the door opening of the autoclave. The gasket is pressed against the
door by steam pressure introduced into the groove behind the gasket.
The interlocking system of the door is based on the following opening conditions:

A door cannot be opened while the autoclave is in operation.

A door cannot be opened if the chamber is under pressure.

A door cannot be opened if there is liquid in the chamber.

Both doors cannot be opened at the same time. Opening of one door
automatically locks the other.
