Using steam under pressure as the sterilizing agent for wrapped or unwrapped goods such as fabrics, surgical instruments, utensils, and other heat and moisture stable materials at temperatures from 105°C to 138°C.
The Azteca Sterilizer is a pre-vacuum/gravity Sterilizer designed to cover a large field of applications for hospitals and laboratories, as well as pharmaceutical and bio-technological industries.
The Sterilizer operates with saturated steam and has an operating range of up to 2.5 bars / 138°C.
Within the health care services, sterilization of medical supplies is an essential issue in the battle against the advance of many infectious diseases. In order to improve the quality of sterile supply, international standards, which specify the requirements for the equipment, and procedures in the sterilization departments in health care facilities, have been developed.

The Azteca Sterilizer meets the highest standards requirements for quality, safety and operation. Stainless Steel Pressure Vessels 316 L conforms to the Pressure Equipment Directive (PED). The inner shell, door(s) and jacket are designed for a maximum working pressure of 2.5 bars and full vacuum. The Sterilizer is heated by saturated steam supplied through a central building source or a stand-alone electrical steam generator.

The Vessel is double-wall constructed with a square chamber, dimpled jacket and reinforcing members constructed of 316L stainless steel within a stainless steel jacket skin, insulated with a fabric covered glass wool.

The Sterilizer can be supplied with one or two automatic vertical sliding doors, with a pneumatic piston. The closing and opening of the door is made through an air- operated valve.
The automatic vertical sliding door’s movement stops immediately if it is obstructed and goes back to the opened position. Special safety features prevent the operator from opening the door when the chamber is pressurized or when the temperature is high.
For the two doors version: When one door is opened, the other cannot be opened at the same time. A Clean side door in the bio-hazard Sterilizer opens only after a sterilization cycle has been completed successfully.
The chamber sealing is made by utilizing a heat-resistant silicone rubber gasket, mounted in the door frame groove. The gasket is pushed against the door using steam pressure.

A galvanized steel frame with rustproof painted finish and height adjustable leveling bolts supports the sterilizing chamber, piping and cabinet. The front of the Sterilizer includes a service door (to provide access to the piping components) and a storage compartment for manuals

A Microprocessor control system, state of the art “Freescale” technology, automatically controls all programs including sterilization cycle. The system includes a 5.7” digital touch-screen graphic display, communication, self and remote diagnosis and PC connection for external documentation and printing. It ensures a reliable, safe and user-friendly operation. The displayed information is available for users in a variety of languages.
During the sterilization cycle it measures, controls and shows in digital display: the time, chamber temperature, chamber pressure and sterilization status.
While the power is off, the non-volatile memory keeps the status of the Sterilizer, and the real-time clock, driven by its own back-up battery, keeps running the date and time.

The Azteca Sterilizer is equipped with an Energy Saving Mode which is activated when the unit is not used after a certain period of time. This Mode will save energy and will insure safety of operation.

Depending on the state of the input and of the installed accessories, the controller is capable of displaying and/or printing several alarms including:
-Door Unlock
-Temperature/ Pressure Error
-Low/High Temperature
-Low/High Pressure
-Low Vacuum and more.

Up to 12 sterilization and test programs are available between 105ºC and 136ºC: four (4) for unwrapped instruments (gravity), four (4) for wrapped instruments and packages (vacuum), and two (2) for liquids. The two available test programs are the Vacuum Test for checking the integrity of the chamber and piping system and the Bowie & Dick test which checks the efficiency of the sterilization process.

For a clear and concise documentation of process, the control unit is provided with a 24 character per line printer, connected to the processing unit. This releases a hard copy printing of the relevant information concerning operation during the cycle such as temperature, pressure, vacuum, sterilization and drying time, number of cycles, etc. In case of an uncompleted cycle, the print-out indicates the cycle failure and the cause for the failure.
RS485/ RS232 PC communication port is available for full documentation and optional advanced PC Windows based software is available for monitoring, logging and control.
A circular or strip temperature and pressure chart recorder can be supplied upon request.
