9.2.2 Stepped configuration
Humidifiers are mounted above one another; offset horizontally (fig. 7 and 8).
Mounting example on tubular frame (on site) with NKBD mounting brackets (Item No.
2000105).
Stepped configuration is necessary
if the permissible air velocity would be exceeded on standard configuration or
if more humidification is necessary than would be possible with the standard con-
figuration. The minimum vertical distances are smaller than with the standard con-
figuration, which permits installation of more units and thus increased humidifica-
tion.
Requirements:
With stepped configuration, the vertical distance between several humidifiers must
be ≥ 70 mm
The minimum horizontal distance between several humidifiers must be
≥ 80 mm.
Several humidifiers should be evenly distributed over the entire duct width, observ-
ing the minimum distance of 200/100 mm from the duct walls.
