HSI, a leading manufacturer of centrifugal blowers, exhausters, and control systems, was acquired by Atlas Copco in 2012.
Over the course of four decades, Houston Service Industries (HSI) evolved into a leading manufacturer of multistage centrifugal blowers, high speed turbo blowers (the ZM range can even process gases!), complete blower packages, exhausters, and process control systems. The company also provides a complete array of aftermarket parts and services for centrifugal blowers, including in-factory blower overhauls, on-site blower troubleshooting and repair. Industries where HSI blower technology can be found include pneumatic conveying, wastewater treatment, landfills, and the general industrial sector.
Atlas Copco acquired HSI in January 2012, with the company's products and branding being fully incorporated into the Atlas Copco portfolio within the past few years.
