This year cleanroom operators will invest more than $5 billion in new cleanrooms. This is the latest forecast in World Cleanroom Markets. These investments include enclosures as well as the air treatment to keep air pure. The Industrial Internet of Things (IIoT) is already being utilized in many cleanroom facilities. However, the future promises radical changes due to IIoT. Sensors detect air flow and cleanliness at various points in the cleanroom. With the laminar air flow concept and velocities approaching 100 fpm a 30,000-sq. ft. semiconductor cleanroom is moving 3 million cfm. This air movement requires fans which use large amounts of energy. IIoT offers a route to reduce this energy consumption through two options. One is better control of the air flow in the traditional ball room cleanroom. A ballroom cleanroom is one where a number of people in special clothing are operating the equipment. These people are the largest source of contamination. However, their movement within the cleanroom has recently been identified as being an important factor. With IIoT it is possible to supply sensors which measure velocity at various points within the cleanroom and at the same time measure air purity. By using variable speed fans tied to the measurement system, the air flow and energy consumption can be varied to maintain cleanliness with less total energy consumption.
