KE-DireJet® System

The KE-DireJet® System is produced in the following configurations: round (Ø), half-round (D), or quarter round (½D) ducts and is made of a permeable textile material with rows of conical nozzles for 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 fabric ducts that offers five different nozzle sizes:

  • ½"
  • ¾"
  • 1"
  • 2"
  • 2½"

 

 


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 ones, such as high-bay warehouses or large sports arenas.

The conical nozzles are fitted in holes made of polyester fabric and are secured using a locking ring. The maximum number of nozzles per row per foot is 4 for the ½, ¾ and 1" nozzles. If this is not sufficient, it is recommended to use two or more rows of nozzles.

Where the 2 and 2½"  nozzles are used, it is recommended to use a maximum of two (2) nozzles per foot per row. As the number of nozzles per foot is increased, the individual jets will have an impact on each other, and they will change character from circular (3-dimensional) 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.
