Why textile ducts?

Textile ducts are very well-suited for efficient, uniform, and draught-free distribution of fresh air without "dead zones".

What is a KE-DireJet® System?

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.

Safetrack Arches

Safetrack Dual Arch

Dual Arch mounting brackets utilize the stability of double rails and at the same time they are quick and easy to install.

Large textile ducts will be stably suspended both with and without air and installation time is reduced considerably as the ducts are mounted in a single ceiling rail.

Safetrack Duct Arch

Duct Arch is a pre-bent aluminium rail mounted in hidden sewn-in pockets in the TBV ducts. The Arches reduce sagging when the air is off and prevent popping with ON-OFF start. 

The unique Safetrack is designed in a way so that the Arch brackets is easily clicked onto the ceiling rail without any tools.

Safe 360° Arch

The Safe 360° system consists of removable rings per 1000 mm or 500 mm. The stainless steel rings are locked with velcro (12, 3, 6 and 9 o'clock) inside the ducts so that they can easily be removed for washing. 

The ducts will keep looking inflated, and it is our best solution if popping is a big problem.

Curved textile ducts

Product development of the TBV design now enables us to offer curved textile ducts designed for a specific radius and with Safetrack rails that follow the shape of the duct. This product can naturally be combined with both ordinary passive low impulse systems and with our hybrid solution in which the low impulse system is made with lasercut inject holes.

A good example i below system that KE Fibertec supplied to Algida Unilever's main office in Istanbul.

Mount Easy

For systems with difficult access, for instance in swimming pool areas where the TBV systems are suspended above the pool KE Fibertec offers a solutions with cord pull called Mount Easy. The Mount Easy system enables a single person to install textile ducts of up to 40 metres from one end.

Coloured rails

Specific types of suspension systems are now also available in any given colour. All visible parts are powder coated in a high impact-resistant quality.

SafeSlider - combi solution for rails and wire

Clips and glider in the same stable solution. The SafeSlider is turnable if you want to change from rail to wire or vice versa. Fits other types of rails - also other makes and it is available in different colours.
