Cleanroom installations are already highly advanced due to their role in creating an ultra-clean working environment. In the new cleanroom of Sioux Technologies Assembly in Eindhoven, Kuijpers added another element: an energy-efficient configuration of the air treatment system. This setup ensures optimal cleanliness by allowing each fan filter unit in every room to be individually adjusted and controlled.
Sioux Technologies is an innovative technology company specializing in the development and production of technical products and solutions. Clients hire Sioux for its expertise or outsource projects to its 700 specialists in areas such as technical software, mechatronics, electronics, mathware, and assembly. Sioux helps companies improve their products, processes, or services, supporting them in research & development or acting as their R&D and Production department.
Kuijpers carried out this construction project as the main contractor, together with other partners from the Professional Partners for Cleanrooms (PP4C) alliance. This is a collaboration between several renowned companies specialized in the design, furnishing, and construction of cleanrooms.
At Sioux, Kuijpers was not only the main contractor but also responsible for all technical installations, including air treatment, cooling, heating, and all electrical systems such as the fire alarm system, lighting, and power supply. The associated control technology and the cleanroom management system were also developed by Kuijpers professionals.
A standout feature of this project is the air treatment system implemented by Kuijpers: individual Fan Filter Units (FFUs) with HEPA filters (designed for extremely high air quality in the cleanroom) are installed in the ceilings and can all be accessed individually via the cleanroom management system. This allows each unit to be adjusted separately; the system visualizes various parameters, such as electrical power consumption, in a clear overview.
This enables Sioux to filter the space flexibly and assess filter contamination effectively. This setup makes the air treatment more energy-efficient than many other cleanroom systems. The idea originated from Kuijpers project manager Vincent van der Molen. “Normally, FFU control is very basic. That makes it difficult to detect trends in filter contamination.
A shame, because FFUs account for a significant portion of energy consumption.” Kuijpers developed and tested the idea in collaboration with a software developer; Sioux was open to implementing this innovative design.
The design provides a solution that allows the high-tech supplier in Eindhoven to filter the air in its rooms—or parts of them—in a more energy-efficient way. It also enables better assessment of which parts of the cleanroom place more strain on the filters. This not only saves energy, but the integration with the cleanroom management system also allows Sioux to monitor the condition of each filter at any time of day. This way, they can keep a close eye on cleanliness—and thus performance. Another advantage: remote monitoring via the cleanroom management system also makes it possible to conduct measurements for further energy optimization.
