Air routing
3 - 86
For wall-mounted units
Used in conjunction with climate control side panels and
TopTherm wall-mounted cooling units for targeted air routing
of the cold air in a downward direction. Particularly well-
suited for densely-packed electrical components in the lower
section of the enclosure.
See Cat. 33, page 475.
Air diverter systems
For TopTherm roof-mounted cooling systems
It is possible to route the cold air directly to specific areas
of the enclosure using the air duct system. The risk of “short
circuits” in the air circulation due to self-ventilated installed
devices is therefore eliminated.
Note:
 Never direct the cold air flow straight at active compo-
nents.
 Route the air duct system directly downwards with no
bends.
 Cold air must be able to escape unobstructed at the end
of the duct.
 Additional deflections will reduce the useful cooling output.
 When using the ducting system, the performance of the
cooling unit may be reduced, depending on the respec-
tive application.
The air duct system should not be extended.
CAUTION Risk of icing!

Air duct system
For TopTherm roof-mounted cooling systems
For sealing cold air outlets that are not required in cooling
units and air/water heat exchangers.
Note:
At least two outlet openings must always remain open!
Please note that if two or three openings are closed, the cool-
ing output may be reduced by 20% and 30% respectively!
