Turnkey ethylene oxide (EO) sterilization equipment for safe and efficient sterilization

STERISYS EO Sterilisationsanlagen Gesamtansicht

In the manufacturing process of a medical device, sterilization is the last and one of the most important steps. Approximately 60% of the medical devices manufactured worldwide are sterilized with ethylene oxide (EO or EtO for short), making it one of the most commonly used sterilization processes. As sterilization with ethylene oxide is effective at low temperatures, this process is ideal for single-use devices and thermoplastic products

In the case of ethylene oxide sterilization, there are basically two different sterilization processes:

  • vacuum sterilization;
  • overpressure sterilization.

At STERISYS, we focus on the engineering and construction of turnkey sterilization equipment for the EO vacuum and overpressure processes. Therefore, we provide you with support right from the beginning: from consulting on the sterilization process, to engineering, installation and commissioning at customer site, through to maintenance.

As one of the leading manufacturers of turnkey ethylene oxide sterilization equipment, we supply our flexible and innovative solutions to international medical device manufacturers and sterilization service providers.
