Upgrade Your Gas Systems with Smart Automation and Modern Reliability
Today’s high-performance fabs, laboratories, and cleanroom environments demand more than just safe gas delivery—they require intelligent control, seamless integration, and system longevity. Many facilities still rely on legacy gas systems installed decades ago. While these platforms may continue to deliver gas reliably, their controllers and gas panels often become the weakest link due to part obsolescence and lack of OEM support.
At Critical Systems, Inc. (CSI), we solve this challenge with state-of-the-art automated control systems and universal gas system controllers. Whether you're retrofitting an aging gas delivery system or upgrading to more advanced automation, CSI offers the most robust and scalable solutions on the market today.
