Make your System Zero Emissions
The Andersen AN5200 abator is a simple, drum-based system designed to remove more than 99% of the EO from the exhaust stream of an EOGas 3 sterilizer. The replaceable drum employs a dry catalyst resin that converts ethylene oxide to biodegradable organic compounds. The replaceable abator drum has a 1,800-cycle capacity. Spent drums are non-hazardous.

Why Ethylene Oxide?
There are many benefits to ethylene oxide sterilization, some of which may be crucial to your hospital or clinic, especially when reprocessing complex multi-channel endoscopes and delicate medical devices. Andersen’s FDA-cleared sterilizers offer several advantages, including low per-cycle cost, low-temperature operation and EO-Flexible Chamber Technology, which allows our systems to use a microdose of EO — just 17.6 grams per cycle. Our systems are able to achieve terminal sterilization (10-6 SAL) with 90% less EO than our competitors — this is ethylene oxide sterilization reimagined.
