Industrial EtO Gas Sterilizer

ERNA Ethylene-oxide gas sterilizers are designed to sterilize thermo-labile equipment and packed disposable medical products at low temperatures (37 – 550 C).

Sterilizers are designed for the specific client projects with modular systems such as: EtO gas circulation, automatic bottle changeover, EtO scrubber and EtO / H2O concentration sensor.

A printer is standard part of each ERNA sterilizer. It starts with printing the date, program selected and parameters of the program. Time,temperature and pressure is recorded periodically. Optionally, a paperless – electronic recorder can be integrated to the sterilizer control. The graphs of temperature and pressure is saved in its flash memory and stored for years in the PC.

The automatic unit mainly consists of an industrial type microprocessor, namely PLC. It is reliable with its high
quality and international approvals. It controls all the sterilization process and parameters. With the help of a modem, it is possible to be online with the PLC and to download new programs from the ERNA center.

The operator panel is a touch screen. Program parameters and cycle information are displayed on the panel. Program selection, start, interruption and manual control is achieved by using the touch panel. They have internationally accepted approvals and high quality. Different types of display can be used in the system, in order to monitor the process.

ERNA Ethylene-Oxide Gas Sterilizers have six user programs and leakage test programs. The parameters of user programs can be set by authorized person. It is possible to customize programs prior to delivery, according to requirements of the user.

The printers is heat and humidity resistant. It records all the sterilization process and parameters. The printer is a panel type printer and can be assembled easily to the sterilizer.

The integrated electrical steam generator is designed to supply necessary saturated steam for the sterilizers. It is controlled by PLC and a pressure switch, for safety.

EtO Sterilization Main Parameters

  • Temperature
  • EtO Concentration
  • Humidity
  • Exposure Time

All these parameters define the pressure inside the chamber.
