De Nora buys ChlorGuard to widen gas feed safety lineup

Industrie De Nora said June 17, 2026, it acquired PSI Global’s ChlorGuard division to expand its Capital Controls gas feed portfolio and strengthen its integrated water treatment strategy. The move adds safety shutdown systems to De Nora’s gas feed and monitoring stack as the company prepares to showcase the combined offering in Singapore.

Why it matters: - The acquisition gives De Nora a broader safety-critical gas feed offering at a time when municipal and industrial water treatment systems face tighter performance and compliance demands. - Combining gas feed, gas scrubbing, toxic gas monitoring and shutdown systems supports De Nora’s push toward fully integrated water treatment platforms. - The deal reinforces Capital Controls as a core brand in De Nora Water Technologies’ strategy for gas handling solutions.

What happened: - Industrie De Nora announced the acquisition of the ChlorGuard safety shutdown systems division from PSI Global on June 17, 2026. - The company said the purchase expands its Capital Controls gas feed portfolio. - De Nora said the transaction strengthens its broader water technologies platform and its “Total Plant Safety” approach.

The details: - ChlorGuard’s safety shutdown technology will be combined with Capital Controls gas feed systems, gas scrubbing technologies and toxic gas monitoring solutions. - De Nora said the combined portfolio is intended to simplify system design, reduce operational risk and support compliance with stricter safety and performance requirements. - Capital Controls has served as an industry benchmark for gas feed solutions for more than 65 years, according to De Nora. - De Nora Water Technologies said the acquisition builds on its long-standing focus on safe and reliable gas handling. - The company said the move advances its ambition to deliver unified and competitive solutions for customers.

Between the lines: - The acquisition signals that De Nora is leaning into end-to-end system integration rather than selling stand-alone components. - Marwan Nesicolaci, CEO of De Nora Water Technologies, said the company is investing to widen its competitive advantage and provide a complete safety and gas feed solution from a single source. - De Nora framed the purchase as part of a market leadership strategy, not just a product line expansion.

What's next: - De Nora will present the expanded gas feed and safety portfolio at Singapore International Water Week. - Visitors will be able to see how Capital Controls and ChlorGuard technologies fit into the company’s Total Plant Safety initiative. - De Nora said attendees will also meet company experts to discuss safer, more resilient and future-ready water treatment systems.

The bottom line: - De Nora is using the ChlorGuard acquisition to deepen its role in safety-critical water treatment equipment and to push harder toward a single-source, integrated offering.
