Closed-loop Controls for Minienvironments in Cleanrooms

Implement a closed-loop cleanroom control system at a reasonable cost

Cleanrooms today are made up of various sized environments needing control and monitoring. From the ballroom style “clean” working areas to the bench-level workspaces, fan-powered clean spaces are required to meet the customer’s requirements. Often, to ease cost constraints, there is a growing placement of higher purity cleanroom minienvironments inside a larger ballroom space.

Howard Abramowitz, President of AirCare Automation, explains that there is a growing placement of higher purity cleanroom minienvironments inside a larger ballroom space.

AC fan-powered systems continue to be the major building block in these situations, as cost barriers continue to reduce the appeal of higher efficiency DC brushless platforms. Additionally, innovations in AC fan-powered control systems have improved the cost, performance, and efficiency of the AC driven system. This is closing the gap between the lower cost AC driven FFUs and the more expensive but more efficient DC brushless driven solutions. This article reviews present systems, closed-loop control implementations, and the resulting improved cleanroom systems capabilities.
