The load capacity is defined by the cross section of the aluminum profiles used. Nordair Systems uses 90 × 90 mm heavy-duty profiles for demanding requirements, which have an additional point load of at least 40 kg per segment Record safely (e.g. for monitors or filter technology) and at the same time stabilize vibration-sensitive processes due to their high mass.
The structural integrity of a Nordair Systems cleanroom tent is not based on simple plug-in systems, but on industrial aluminum construction profiles. For applications with increased requirements (e.g. housing of optical tables or large spans), we use profiles with a cross section of 90 × 90 mm one. This geometry offers an extremely high moment of inertia, which reduces deflection to a physical minimum even in wide designs.
A crucial parameter for engineering is usable additional load. Each individual profile segment is specified to add an additional weight of at least 40 kg without jeopardizing the overall statics. This is relevant for the integration of:
These loads are formally introduced into the structure via slot blocks, which effectively distributes point loads over the profile flanks.
In addition to the pure load capacity (N/mm²), the mass of the 90 profiles plays an important role in Vibration control. In photonics and microscopy, even microscopic vibrations caused by fan motors can falsify measurement results. The high mass of the Nordair construction acts as a passive damper that absorbs resonance frequencies and thus creates a more stable process environment than thin-walled 30 or 40 mm systems.
