- Five grades of safe measures, efficient and reliable.
Inverted Pressure Sterilized Boiler Working principle:
Counter-pressure method: During the cooling process after sterilization of tested items (bags), the temperature inside the bag remains higher than outside the bag in the tank, and this can cause pressure difference and make the bag burst. To prevent the bursting, we can inject balancing pressure (counter-pressure) air during the cooling process to keep pressure in the tank and eliminate the pressure difference while temperature decreases gradually.
