SteriSpace CATOX Emissions Abatement System
Product Code: NSSA
The SteriSpace® YFS CATOX Electric Recuperative Catalytic Thermal Oxidizer is a fully electric EtO and PPO emissions abatement system designed for safety, reliability, and energy efficiency. Using compressive heat and catalytic oxidation, the system reduces Ethylene Oxide to 5 PPB and Propylene Oxide to 10 PPB residual levels. Built with all stainless-steel components and a gas-tight design, YFS CATOX requires no gas train and minimal maintenance. Each unit is shop-assembled, pre-wired, tested prior to shipment, and engineered for high-capacity process and fugitive emissions control.
