The Azteca AC steam sterilizer family consists of pre- and post-vacuum sterilizers, autoclaves, designed with the highest quality for sterilization of wrapped or unwrapped goods such as fabrics, surgical instruments, utensils, and other heat and moisture stable materials. With their large capacity from 75 up to 200 liters they cover a large field of applications for dental, veterinary and small clinics, hospitals and operating rooms (OR).

These models have been sold to 40+ countries in Europe, the Middle East, Latin-America, Africa and Australia, and are highly recommended by doctors and professionals.


All components used have been selected with proper attention, meeting the highest quality standards’ requirements from known leading companies with the most advanced technologies around the world.

The construction of these autoclaves is modern, ensuring reliable operation, incorporating high-tech features. Behind its success is a team of multi-disciplinary engineers, who have developed sterilization equipment on OEM basis for leading manufacturers in the world, for more than 20 years. 


The vessel is a heated jacketed round chamber, made of corrosion resistant stainless steel 316L, which conforms to the Pressure Equipment Directive (PED). The highly efficient, high quality Hanno-Tech insulation material releases no particles; thus, the Azteca AC steam sterilizers can be used under clean room conditions. The advanced insulation technology further contributes to the high energy efficiency of the sterilizer units.

The autoclave is supplied with either 1 or 2 hinged door(s) with an automatic door locking device. Special safety features prevent the operator from opening the door when the chamber is pressurized or when the temperature is high.

The Azteca AC steam sterilizers use steam under pressure as the sterilizing agent at temperatures ranging from 121°C to 134°C. The units are standard equipped with internal steam generators to enable faster cycles with low energy consumption. The large capacity of the heaters inside the steam generator enables steam to always be ready for operation.

The air removal is done by a powerful vacuum system, using a liquid ring vacuum pump and a condenser, heat exchanger.

All autoclaves are standard supplied with a water saving system to reduce the amount of water during the sterilization cycles.

Through the numerous safety features, the Azteca AC steam sterilizers meet the highest standards and requirements for quality, safety and operation (EN 285 – Large Steam Sterilizers standard; Pressure Equipment Directive (PED); Medical Device Directive MDD 93/42/EEC; EN 60601-1, EN 61010-1 and EN 61326 safety standards, etc. and CE approved). 


A microprocessor based control system; state of the art Freescale technology automatically controls all operations. The system includes a digital color touch-screen LCD display, communication, self and remote diagnosis and PC connection for external documentation and printing, ensuring a reliable, safe and user-friendly operation. The displayed information is available for users in a variety of languages.

Azteca AC Series offer 7 preset cycles, 5 sterilization cycles and 2 test cycles to assure a proper sterility level. Up to totally 20 cycles can be custom designed according to the users’ needs. 


With a range of accessories these autoclaves can be easily customized according to the customer’s requirements. 


The modular design of all internal and external components together with the self-diagnostic system ensures easy maintenance, resulting in reliable service and performance and satisfied operators.

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 this supply, international standards have been developed, which specify the requirements for the equipment, and procedures in the sterilization departments in health care facilities. Celitron’s Azteca AC autoclaves provide the best solution for dental, veterinary and small clinics, hospitals and as secondary sterilizers for emergency cases in operating rooms (OR).
