Ingersoll-Rand (IR) Acquires SSI Aeration

Ingersoll Rand Inc., (NYSE: IR) a global provider of mission-critical flow creation and life science and industrial solutions, has acquired SSI Aeration, Inc. and its subsidiaries (collectively “SSI”) to extend its capabilities in wastewater treatment.

SSI is a global leader in the design and manufacturing of wastewater treatment plant equipment with approximately $30 million in annual revenue. Its product portfolio is focused on innovative and energy-efficient engineered membrane diffusers including fine bubble diffusers, coarse bubble diffusers, and aeration systems. The acquisition will enable Ingersoll Rand to combine several technologies like low pressure compressors with SSI’s aeration offerings to provide a comprehensive, end-to-end solution. With manufacturing facilities in the United States, South Korea, and India, SSI will join the Industrial Technologies and Services segment (IT&S).

“Inorganic growth remains a key part of our company’s overall growth strategy in 2025,” said Vicente Reynal, chairman and chief executive officer of Ingersoll Rand. “We look at potential acquisitions through the lens of how they will help us optimize our solutions, and we look forward to growing our presence in the wastewater treatment market with the addition of SSI.”
