Examplary design of guide rails for a vortex

module wall

Pos. 1: upper guide rail

Pos. 2: vortex module wall

Pos. 3: spacer or direct connection floor of chamber

Pos. 4: lower guide rail

Pos. 5: humidification chamber

Inner dimension of guide rail: 62 mm

Hight: please see above sketch

Material: 1.4301 stainless steel sheet, thickness: 1 mm

7.3.3

Side rails for the vortex module wall:

If the wall consists of 11 or more vortex module rows side rails
are required in order to avoid bending of the vortex module wall.

Having more than 16 vortex modules in horizontal position the
the vortex module wall has to be vertically separated into two
halfs, that are separately fixed by side rails
