Trusted Compliance: CARULITE® 500 Catalyst & Picarro Deliver Proven EtO Emissions Control

March 5, 2025

Meeting the EPA Subpart-O NESHAP regulations for ethylene oxide (EtO) emissions requires abatement systems to achieve up to 99.99% destruction removal efficiency (DRE)—a challenge when legacy monitoring systems lack the sensitivity to accurately measure compliance.

Together, Carus and Picarro have demonstrated that CARULITE 500 catalyst surpasses compliance thresholds, achieving an incredible 99.99988% DRE—far exceeding regulatory requirements. Backed by Picarro’s advanced emissions monitoring technology, this solution provides the trusted, real-time data needed to ensure compliance, efficiency, and environmental responsibility.
