We’ve mentioned it many times before: every square meter Cleanroom costs energy during operation. That’s why we always plan a system to be as large as necessary and as small as possible. However, as the operating costs are mainly caused by the required air changes, it’s not just about the surface area, but also about the volume.
According to our guiding principle “as much as necessary, as little as possible”, the question arises as to how high a Cleanroom MUST or SHOULD be.
Theoretically, we can design the height of our cleanrooms flexibly. We build high if tall machines are used in the Cleanroom. Low in exceptional cases, if the hall in which the Cleanroom is installed has a room height that is too low, as space must be planned for the air flow between the cleanroom ceiling and the hall ceiling.
As a rule, however, the height of the cleanroom is based on the Workplace Ordinance. Workspaces (including cleanrooms) must have a sufficient clear height depending on the floor area. The following are standard dimensions
| Base area | Minimum height |
| up to 50 m² | 2,50 m |
| 50 m² – 100 m² | 2,75 m |
| 100 m² – 2000 m² | 3,00 m |
| more than 2000 m² | 3,25 m |
The height of a cleanroom is therefore essentially based on the well-being of the employees, as stipulated in the Workplace Ordinance. We usually plan with the minimum height in mind.
