Safe and efficient low temperature sterilization
EO sterilization is used on heat/moisture sensitive products. The sterilization process allows the product to remain packed and palletized for the entire process, and is ready to ship without the need for additional re-packing or handling.
The EO sterilization process consists of three stages. These stages can be performed within the sterilizer chamber or in three separate chambers.
In the pre-treatment stage the load is heated and humidified to prepare for sterilization.
The load is sterilized with the correct concentration of EO gas at low temperatures.
In the post-conditioning stage, the gas is removed from the product and packaging for safe downstream handling.
To ensure rapid heating and a consistent load temperature, heated water is circulated through the jacket and doors. If required, a cooling system can also be included for rapid transition to lower temperatures.
The chamber recirculation system is essential to ensure uniform gas and temperature distribution. The external distribution piping is heated to maintain temperature and minimize losses.
GEE EO Sterilizers are equipped with liquid ring vacuum pumps providing efficient air removal of sterilizer chamber and internal load. The vacuum system removes high concentrations of EO from the chamber in a short period of time.
EO is usually supplied as liquid in pressurized containers. Vaporization ensures that liquid EO does not enter the sterilization area. The heating medium can be either steam or hot water for accurate temperature control and flow regulation.
GEC Water Cascade Sterilizers are primarily intended for terminal sterilization of large volumes of liquids in sealed glass or plastic containers.
The loading system is an integral part of efficient and user-friendly operation of any sterilization system. Getinge supports you with expertise and a wide range of loading equipment for many diverse applications.
