8.2 Katherm HK – Supply air ducts ZL
The Katherm supply air trench ZL is available for all
trench heaters (Katherm range). This represents a
400 mm long trench, which can be fitted to all
designs of Katherm units. Treated supply air can
also be fed into rooms through the Katherm supply
air trench ZL. This is achieved with different sizes/
designs of spigots for the most diverse trench
dimensions.

Adjusting the slider positions
The supply air model, like all standard Katherm units, is
adjusted in height via the adjustment screws and fixed to
the floor via the adjustment feet. To set the desired flow rate
at the supply air module, you can move the slider in various
positions. The illustration on the left shows 4 different slider
positions (100%, 75%, 50% and 30% open). They are also
shown in the design diagrams below, where you can read off
the desired pressure losses, sound levels and air flow rates.
Intermediate values can be interpolated.
