KE-DireJet® System

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 ventilation.

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 sports arenas.

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.
