Basic Functions of ventilated autoclave sterilizer:<\/strong>
autoclave sterilizer<\/span>\u00a0utilize a process that combines clean steam and air pressure for sterilization. This method effectively controls the pressure balance and back-pressure protection of both the equipment and the products. It has gained widespread application and achieved excellent results in sterilization fields where maintaining and protecting the shape and sealing of items is crucial. The forced convection fan and airflow guide plate structure ensure uniform mixing of unsaturated steam inside the chamber, guaranteeing consistent sterilization temperatures. The equipment is equipped with internal cooling coils, and the cooling and drying of products are achieved by introducing cooling water into the condensation coils to condense the mixed gases inside the sterilization chamber. Cold air flows over the products to cool them, while the moisture on the product surfaces evaporates, ultimately achieving the goals of cooling and drying. For products with higher drying requirements, a hot air drying function can be added.<\/p>

2. Main Performance Features<\/h3>
  1. Motorized door with automatic opening and closing, using inflation pressure to drive the sealing ring for automatic sealing.<\/li>
  2. Double-door pass-through design, equipped with pressure safety interlock and temperature door safety interlock, ensuring effective isolation between the sterilization area and the sterile item storage area through dual door interlocking.<\/li>
  3. *Brand new high-quality tear-resistant silicone rubber circular hollow door sealing ring, surface treated with polytetrafluoroethylene (PTFE) coating, wear-resistant and smooth, providing better sealing effect and longer service life of up to 1500 cycles. The good fit between this sealing ring and the sidewall of the sealing groove reduces the chance of compressed air leaking into the inner chamber, thus ensuring sterilization effectiveness.<\/li><\/ol>

    2.2 Pressure Vessel (Main Body and Door):<\/h3>

    (1) *Horizontal\u00a0autoclave sterilizer\u00a0<\/span>with a rectangular cross-section, European (GETINGE) annular reinforced jacket structure. The unique combination of the inner shell and annular jacket enhances the strength and stiffness of the main body, resulting in higher load-bearing capacity and lower stress concentration compared to integrated jackets. This design provides superior loading capability, especially under pulsating alternating pressure and temperature loads, leading to longer fatigue life of the vessel. (2) The bottom surface of the inner chamber has a certain slope to ensure the discharge of condensate.\u00a0<\/p>

    (3) Materials in contact with steam such as the inner tank and door panels are made of 316L stainless steel; door teeth and main body stops are also made of 316L stainless steel, while the jacket is made of high-quality carbon steel specifically designed for pressure vessels.\u00a0<\/p>

    (4) *Sealing groove structure: The sealing groove is directly welded onto the annular jacket at both ends (GETINGE structure), preventing cracks often caused by excessive rigidity in corner arcs of integrated flange structures, and the jacket is close to both end faces, improving drying efficiency.<\/p>

    \u00a0(5) *The longitudinal seam of the inner tank is welded using plasma automatic welding technology, with robotic automatic welding for the jacket. Post-welded components undergo vibration aging treatment to relieve stress and eliminate welding stress, effectively enhancing the structural stability and performance of the main body and door assemblies.\u00a0<\/p>

    (6) The surface of the inner tank and door is polished to a mechanical mirror finish with Ra 0.6, providing strong corrosion resistance.<\/p>

    2.3* Siemens Programmable Logic Controller (PLC) and Color Touch Screen:<\/h3>

    The entire process is automatically controlled by a program, displaying operational status, temperature, pressure, and time parameters.<\/p>

    2.4 Communication Verification Interface:<\/h3>

    Equipped with a communication verification interface with standard size DN25, optional DN40.<\/p>

    2.5 Programs Supported:<\/h3>

    Pre-filled syringes, PP aluminum-plastic packaging, PP cups, instruments, stainless steel tanks, sterile clothing, glassware, liquids, culture media, and custom programs.<\/p>

    2.6 Sterilization Temperature:<\/h3>

    Adjustable from 105-136\u2103, freely set to 134\u2103, 121\u2103, or 113\u2103.<\/p>

    2.7 Real-time Data Printing:<\/h3>

    Real-time printing of process data via built-in mini printer and paperless recorder. The thermal printer records may not be suitable for long-term preservation. It prints the sterilizer’s temperature, pressure, sterilized items, sterilization time, and operator information (including curve printing).<\/p>

    2.8* Piping System:<\/h3>

    Pipes that come into contact with pure steam and connect to the inner chamber are made of 316L stainless steel, secured with clamps, and all welds are done using automatic pipe welding machines. Pneumatic valves have a fault-free operating life of \u2265 4 million cycles.<\/p>

    2.9 Automatic Drainage Temperature Control System:<\/h3>

    Drainage temperature \u2264 55\u2103.<\/p>

    2.10 Air Filter:<\/h3>

    The filter housing should be made of 316L stainless steel, and the filter element should be hydrophobic PTFE, with a filtration precision of \u2264 0.22 microns, achieving a sterilization rate of 99.97%.<\/p>

    3. Safety Devices and Alarm System<\/h3>

    1. Automatic Overpressure Protection Alarm Function<\/strong>:<\/p>

      • The pressure control for the jacket, inner chamber, and evaporator (if present) utilizes imported analog pressure transmitters for intelligent control, replacing manually adjustable mechanical pressure switches. This system continuously monitors pressure data and automatically triggers protection and alarms in case of overpressure.<\/li><\/ul><\/li>

      • Safety Valves<\/strong>:<\/p>

        • Safety valves are installed on the jacket, sterilization chamber, and evaporator (if present). If the safety opening pressure is exceeded, these valves will automatically open to relieve pressure.<\/li><\/ul><\/li>

        • Over-temperature and Under-temperature Alarm Function<\/strong>:<\/p>

          • The temperature control within the inner chamber employs A-grade precision PT100 sensors to collect temperature data in real time. If the temperature exceeds the set threshold, automatic protection and alarms are triggered. Similarly, if the temperature drops below the sterilization temperature, protection and alarms are also activated.<\/li><\/ul><\/li>

          • Compressed Air Low Pressure Alarm<\/strong>:<\/p>

            • A pressure switch detects the pressure of the compressed air. If the pressure falls below 0.4 MPa, an automatic alarm is triggered.<\/li><\/ul><\/li><\/ol>

              4. Other Functional Features<\/h3>

              1. Pressure Holding Test Function<\/strong>:<\/p>

                • The system can achieve a vacuum down to -0.09 MPa or lower, maintaining pressure for 10 minutes with a leakage rate of \u2264 1.3 kPa\/10 minutes.<\/li><\/ul><\/li>

                • Connection Seals<\/strong>:<\/p>

                  • Connection seals for piping and valves should be made from high-temperature resistant polytetrafluoroethylene (PTFE). Insulation layers should use ceramic fiber blankets, while external decorative panels should be made from SUS30408 stainless steel.<\/li><\/ul><\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
