Horizontal Cylindrical Pressure Steam Sterilizer AM-WS-400/500YDA

Horizontal Cylindrical Pressure Steam Sterilizer AM-WS-400/500YDA

Saturated pressure steam is used to sterilize article, for it will liberate a great amount of heat when condensing. To make the articles (need to be sterilized) hot and wet for a certain time, most resistant bacterial spores will be killed, and then sterilization aim is reached. The method is reliable, economical, and easy to be controlled, so it has been used for more than one hundred years.

This unit is ideal equipment for clinics, scientific research institutes and other organizations to sterilize surgical instruments, fabric glassed, culture media etc.





  1. Sterilizing course automatic sterilization controlled by computer, easy to operate.
  2. With drying function, suitable dressing drying.
  3. With over-temperature, over-pressure auto-protect device.
  4. The door opening mechanism cannot be operated until the pressure in the chamber is reduced to 0.027MPa.
  5. It can’t be start on if the door doesn’t close well.
  6. The safety valve will be open automatically when the inner pressure over 0.24MPa, and the steam be exhausting to the water tank.
  7. The power will be cut -off automatically, cut-off the water and alarm when the machine lacking water.
