The DireJet System is one of two products KE Fibertec offers for active long throw applications. TheDireJet's versatility makes it appropriate for cooling, heating, and mixing ventilation applications to best meet your needs.
The DireJet System is available in the following configurations: round (O), half-round (D), or quarter round (1/2D) ducts and is made with rows of conical nozzles for active and directional delivery. The nozzles limit the induction of room air around the air jet, so the velocity decreases more slowly relative to the Inject System. As a result of this, the throw and thermal penetration lengths are extended considerably with this system.
KE Fibertec is the only distributor of fabric ducts that offers five different nozzle sizes to ensure functionality in virtually every type of space requiring mixed ventilation, even in extremely large premises. The sizes available for your specific usage are:
KE Fibertec designs two products for fabric-based laminar flow applications: the Impulse System and the Impulse D and 1/2D 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 this, the Impulse Systems are suited only for cooling purposes or for distributing large volumes of isothermal air.
The Impulse System is produced using round ducts (O), while the Impulse D and 1/2D Systems are produced using half-round (D), or quarter round (1/2D) ducts. Our ventilation experts can tailor this product to meet your specific room requirements, providing high quality air and comfort in your space.
The Inject System is the second product KE Fibertec markets for active high impulse ventilation. Our Inject System has versatile applications and can be used for cooling, ventilation, and heating purposes.
It comprises groups of holes, small (Inject) or large (Inject XL) in the fabric duct surface, resulting in an induction of the room air on a large scale. It is produced in the form of round (O), half-round (D), or quarter-round (1/2D) ducts and offers so much flexibility in design that it is possible to create solutions specifically tailored to the functions most appropriate for your space.
The air distribution principle for this system is based on mixing ventilation; the supply air at a high velocity outside the occupied zone is entrained towards the jet, eventually decreasing in velocity. In a mixing ventilated room, air velocities, air temperatures, and humidity will be distributed identically,creating the same air quality everywhere in the room for optimal comfort.
