Overview

CRA’s Moisture Traps are engineered to separate and collect condensed moisture formed in biogas pipelines due to cooling and pressure changes. Installed directly in the gas line, the trap uses controlled flow reversal and impingement to coalesce moisture into droplets, which settle at the base for removal. Designed for low-pressure biogas service, the system operates without external power, ensuring reliable moisture removal and protection of downstream equipment.
