600L Pass-Through Double Door Horizontal Steam Sterilizer with Siemens PLC Control

This Horizontal Steam Autoclave adopts saturated steam as the sterilizing medium, ensuring thorough penetration into the surfaces of items through a pulsating vacuum process. Under high pressure, the steam effectively destroys all microorganisms and their spores, providing one of the most dependable and efficient physical sterilization methods. The pulsating vacuum exhaust removes residual cold air that could affect temperature uniformity, while the sterilized items are ultimately dried through vacuum dehumidification in combination with the heating jacket.

Main Parameter:                                                                                                                                    

The autoclave operates with a maximum working temperature of 139°C and a maximum working pressure of 0.25 MPa.
Its vacuum leakage rate is controlled within ≤0.13 KPa/min, while the ultimate vacuum reaches -97 KPa.

For safety, the opening pressure of the inner chamber safety valve is set at 0.28 MPa, and the opening pressure of the jacket safety valve is also 0.28 MPa.

The system provides precise sterilization temperature control within 0–2°C, ensuring a temperature uniformity of ±1°C throughout the chamber.

During operation, the negative pressure pulsation amplitude ranges from -80 to 0 KPa, with vacuum amplitude and times adjustable from 1 to 99 cycles.
Additionally, the positive pressure pulse amplitude ranges from -80 to 80 KPa, with one pulse per cycle, and the number of positive pressure pulses can be set between 1 and 3 times according to process requirements.
