Ethylene Oxide (ETO) sterilizer is mainly used to sterilize medical and pharmaceutical products that cannot support conventional high temperature steam sterilization - such as devices that incompany electronic components, plastic packaging or plastic containers. Normally the ETO used for gas sterilization is mixed with diluents such as carbon dioxide or nitrogen in different proportions from 10 % ETO to 90 % ETO.
- Single or double door With Sliding or Hinged door options to suit client specific requirements.
- Dimple steam Jacketed for better Uniformity of the heat Distribution. (Technology for fast Sterilization cycle and low cost operating)
- Gas evaporation system is provided to ensure gaseous sterilant even at low temperature
- Gas circulation system in place to achieve uniform concentration of ETO gas. This is imperative for chamber volumes above 3 cubic.meter.
- Gas detection system is provided as a safety measure for ETO gas at minimum 3 locations to detect ETO leakage and set an audiovisual alarm.
Emission Control Equipment
- *Acid Base Scrubbers
- *Catalytic Oxydizers
Sterilization Process Temperature and Relative Humidity Recorders
Fully Automatic PLC with Touch screen Control with all Parameter Online Printing facility, Computer Interface Facility with software and remote support facility.
Contamination Seal to prevent cross-flow of air between the clean and un-clean area.
Most ETO sterilization lines involve three different stages. These can be separated into three different cells depending on the size or amount of devices to treat:
- Pre Conditioning
PRE CONDITIONING STAGE
First, products need to go through a pre conditioning phase to make micro organisms grow. The batch load goes through a dwell time under a controlled environment of:
Then the load goes through a long and complex sterilization cycle. Requirements of such a system are:
- Accurate temperature control.
- Availability of the control system.
- Accurate pressure and vacuum control.
- Easy displays of process phases
- Dedicated customer recipes.
- Auto batching release through tolerance tests.
- Security interlocks between actuators.
- Shut down strategies.
