1. Two Autoclaves sterilize in turn. 2. Save time and energy. 3. Uniform heat distribution, no dead angle The temperature and pressure of the Hot Water Immersion is controlled precisely by the PLC. The two sets of Autoclaves can work alternately, using the same sterilizing water. The sterilizing water will be injected to another Autoclave after finished in one Autoclave. It can decrease heat and water consumption and also speed up the production.
