The KE-DireJet® System is produced in the form
of round (Ø), half-round (D) or quarter round
(½D) ducts and is made of a coated,
non-permeable textile material with rows of conical nozzles
for 100% active and directional delivery.
From a ventilation technology perspective, the KE-DireJet System
can be regarded as an active high impulse system for mixing
KE Fibertec is the only distributor of textile
ducts that offers five different nozzle sizes: Ø12,
Ø18, Ø24, Ø48 and Ø60 mm.
The flexibility in the choice of nozzle size offers great
benefits as the KE-DireJet System can then be used in virtually
every type of premises that requires mixing ventilation, even in
extremely large premises, such as high-bay warehouses or large
The conical nozzles are fitted in holes made of coated polyester
fabric and are secured using a locking ring. The maximum
number of nozzles per row per metre is 14 for the Ø12, Ø18 and
Ø24 mm nozzles. If this is not sufficient, it is recommended
using two or more rows of nozzles.
In the case of Ø48 mm and Ø60 mm nozzles, it is recommended using
a maximum of six nozzles per metre. As the number of nozzles
per metre is increased, the individual jets will have an
impact on each other and they will change character from
circular jets to 2-dimensional jets. The velocity rate in the flow
will also slow
down as the induction of room air is limited the closer the
nozzles are placed together.
