■ Manually control for filling water, steam exhaust and drying, automatic control for heating and sterilization
■ Pressure automatic control, precision is ±0.005MPa
■ Steam and water built-in circulate, don’t need water source and don’t exhaust steam.
■ Safety valve can be open if pressure exceeds setting value
■ Door interlock: heating for steam only starts when the door closes. The door can be locked if there is pressure in chamber
■  Overheat protection: the system will shut off the heating power if temperature exceeds setting value
