Function of supply air with supply air modules
The conditioned primary air enters through a
variable number of supply air modules below
the trench unit. It escapes through an outlet slot
arranged along the length of the trench unit and
mixes with the secondary air heated or cooled
by the convector before emerging into the room.
Optimum shielding can be provided in front of the
glazing with a slow and low-turbulence leaving
air velocity. The volume of air supplied can be
conveniently adjusted via the variable number of
supply air modules per trench and the continuously
adjustable slider. Up to 60 m³/h of primary air can
be supplied per supply air module. High volumetric
flow combined with low slider position can lead to
noticeable air flow noises (see adjacent diagram).
The designs of Katherm HK with supply air can be
adapted on a project-by-project basis. The trench
widths are then +20 mm larger compared to the
standard widths of Katherm HK models. The trench
heights increase by +35 mm (HK 320) or +20 mm
(HK 290 and HK 360).
