KE DireJet Textile Ducts (MultiWeave) •
Round (Ø) textile duct for even and draft-free distribution of air.
•
KE-DireJet® ventilation system from KE Fibertec or equivalent approved system, for even and draft-free distribution of cooled and heated air. If required, the air distribution system is supplied with either Ø12, Ø18, Ø24, Ø48 Vario or Ø60 mm plastic nozzles as designed by KE Fibertec to ensure uniform mixing with the room air. It must be documented and ensured that the air enters the occupied zone under the current conditions of the project (installation height, set temperature, air volumes, etc.).
•
The textile ducts must be classified according to the European fire protection code EN13501-1. The classification must be B-s1, d0 (flame spread / smoke spread).
•
The textile material must be permeability-stable and have a maximum shrinkage of 0.5% after washing.
•
The textile material must be Cradle to Cradle certified (min. Bronze) as documentation of its sustainability.
•
The textile material must be approved according to the Oeko-Tex 100 standard.
•
The textile ducts are supplied in the colour xxx RAL xxxx. The final choice of colour must be approved by the site management before the order is placed.
Suspension system •
KE Fibertec SafeTrack® mounting material system (single or double row). Mounting rails made of extruded aluminium with a 10-micron anodized finish. 25 microns optional for swimming pools and galvanising.
•
The length of the rails must correspond to the drawings or be adapted for the installation of textile ducts. The manufacturer must cut the rails to the required length.
•
The textile ducts are suspended in the rails by means of an integrated flexible bulb that slides into the extruded aluminium rails. The raisl are mounted to the ceiling using vertical strap-ups (either galvanised M6/M8 threaded rod or steel cable). The strap-ups are clicked onto the rails with an aluminium suspension profile.
•
Ducts with a diameter of more than Ø1000 mm must be suspended in double Safetrack, with the bulb sewn into the textile duct at 3:00 and 9:00.
Points for BREEAM •
The air velocity in the occupied zone must be provided for the technical documentation with a 2D or 3D flow chart representation in relation to the room temperature. Complies with the requirements of BREEAM according to criterion Hea 04, Thermal comfort.
•
The sound power levels should be calculated for all systems and displayed graphically according to frequencies. Complies with the requirements of BREEAM according to criterion Hea 05, Acoustic performance.
