Large autoclave: principle and technical information

All components used have been selected with proper attention, meeting the highest quality standards 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 and behind its success is a team of multi-disciplinary engineers, who developed sterilization equipment on OEM basis for leading manufacturers around the world, for more than 20 years.

The vessel is a double full jacketed square chamber, made of corrosion resistant stainless steel 316L, which conforms to the Pressure Equipment Directive (PED). The autoclave’s framework and piping are also made of stainless steel. The highly efficient, high quality Hanno-Tech insulation material releases no particles; hence the Azteca A steam sterilizers can be used under clean room conditions. The advanced insulation technology further contributes to the high energy efficiency of the units.

The autoclave sterilizer can be supplied with either 1 or 2 pneumatically operated vertical sliding door(s). 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 door from opening when the chamber is pressurized or when the temperature is high. In double door units both doors cannot be opened at the same time, and clean side door only opens after a sterilization cycle has been successfully completed.

The Azteca A steam sterilizers use 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 121°C to 134°C. The autoclaves can be equipped with internal steam generator to enable faster cycles with efficient energy consumption, and to eliminate the dependence on an external steam source and its steam quality.

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

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