Broad Air Outlet B
When a broader, lateral spread of the air stream is desired, the AL-KO air heaters / air coolers can be equipped with a
Broad Air Outlet Louvre B. The diffusion grid with the vertical guide fins is mounted immediately before the horizontal
outlet louvre. The outside dimensions of the air heaters / air coolers do not change. The spread of the air stream can be
optimally adjusted to the installation conditions.

Outlet nozzle with Slats AD
The Outlet Nozzle AD is used in high halls to increase the throwing distance. The reduced outlet area increases the air
flow speed and therefore the vertical penetration depth of the air stream. Secondary air is pulled along. The Outlet Noz
-
zle AD can also be used with wall-mounted systems. The integrated air direction slats can be adjusted to draw a larger
amount of secondary air.

D1 outlet nozzle (gate air curtain)
Air heating devices with a D1 or D2 outlet nozzle are suitable as air curtain devices at gates. During the installation, care
has to be taken that the air jet must be directed against the gate towards the outside. The D1 outlet nozzles have the
same cross-section reduction as the AD outlet nozzles. The outlet temperature of air heaters used as air curtains at gates
should be selected at approx. 10 – 15 °C above the room temperature. When the gates are rather broad, the D2 nozzle
form is used. The nozzle is wider than that of the D1 nozzles.
