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-Low Impulse System?

The air distribution principle for horizontal low impulse systems is based on passive thermal displacement where the air is supplied at a lower temperature in relation to the air in the room.

Because of the difference in density, with the cooled air being heavier than the warmer air in the room, the room air is displaced below the duct while the supply air continues moving towards the floor.

The air flow in the room is then based on natural air movements where theair is driven by the difference in density and convection streams from heat-releasing activities and processes, hence the term "passive thermal displacement".

A high level of heat activity from heat sources generates bigger convection currents, resulting in the air rising more strongly and greater entrainment of the air around the source. This then results in stratification in the ventilated room where heat and pollution are drawn away from the occupied zone and extracted under the ceiling.

A low impulse system can only be used for cooling purposes or for distributing large volumes of isothermal air, as warm air will settle under the ceiling like a blanket.

When this happens, the supply air is short circuited, which means a waste of energy.

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.
