Dissolved Oxygen Removal System (DORS) for Legionella Control

Recent research shows that controlling dissolved oxygen levels can have a positive effect on your Legionella remediation and mitigation efforts. Oxygen is essential for the survival of Legionella pneumophila in building hot water circuits. The Dissolved Oxygen Removal System uses innovative hollow-fiber membrane technology to extract dissolved oxygen from water and brings it to a level below the survival threshold for Legionella. This safeguards hot water systems from Legionella and other pathogens. The patented technology is positioned to revolutionize the approach to Legionella control and offers an alternative to chemical treatments.

The Dissolved Oxygen Removal System integrates membrane contactors in a patented process to remove dissolved oxygen (DO) to levels that have been proven to inhibit the growth of Legionella in a circulating hot water system in a laboratory and a multi-story apartment building under challenging conditions.

• Designed for circulating hot water systems where Legionella tends to grow.
• Compact design about the size of a commercial refrigerator.
• Connects to existing plumbing with standard components.
• Minimal requirements of electricity, Wi-Fi, and a source of high-purity nitrogen, supplied by compressed gas or an integrated nitrogen generator.
