KE Inject Fabric Systems

High impulse cooling or heating with holes

KE Fibertec has a family of multiple sized laser cut holes for the KE Inject system. The range of sizes allow us to design for the optimum air delivery for the application. The Inject system is made of custom woven fabric that allows the supply air to pass through the surface of the system as well as the laser cut holes making it ideal for heating and cooling solutions.

The key difference between the KE-Inject System and KE-DireJet System is induction, i.e. the ability to entrain room air. The KE-Inject System comprises groups of small holes in the textile, resulting in an induction of room air on a huge scale around the jet. This means that the velocity rate in the jet is reduced more quickly than for the KE-DireJet System, but the throw length and penetration length are also reduced.

The KE-Inject System offers so much flexibility in production that it is possible to create solutions specifically tailored to the individual function. The model which is suitable for the relevant purpose from among flow models 1, 2 or 3 is chosen according to the system’s requirements specifications. Combination solutions including the three flow models can also be used. This may be relevant, for example, if you want to supply heated air, where flow model 2 or 3 is recommended, while also coating the ceiling (flow model 1) to prevent the formation of condensation, which often occurs in food production processes, for instance.

KE Fibertec markets multiple types of KE-Inject Systems, with their characteristic patented hole design running along the duct’s longitudinal surface. The number of holes per metre is constant, regardless of the length of the duct. The only option for adapting the number of holes to the relevant volume of air is by having more or fewer rows of holes on the duct’s circumference. Consequently, KE Fibertec indicates the number rows of holes in a dimensioning context. This should then be understood as the total number of hole rows placed on the duct’s circumference, with the holes grouped in a particular design along the duct’s longitudinal surface.

KE-INJECT LOW VELOCITY (LV)

The hole design for the KE-Inject Low Velocity System comprises 21 holes per row, followed by 21 steps without holes. One characteristic feature of KE-Inject Low Velocity is that it helps achieve a particularly good mixing capability. The high level of induction of air around the duct results in a reduction of the throw length, which means that large volume flows can be delivered, along with a large cooling load per m2  of the floor area. See datasheets 7 and 8 for further information.

KE-INJECT MEDIUM VELOCITY (MV)

The hole design for the KE-Inject Medium Velocity System comprises 33 holes per row, followed by 9 steps without holes. A good mixing capability is also typical of this system, but it is better suited to supplying warm air, compared to KE-Inject Low Velocity. See datasheets 7 and 9 for further information.

 

KE-INJECT JET (JET)

The hole design for KE-Inject JET comprises 42 holes per row. There are no steps between the sections of holes. A typical feature of the KE-Inject JET System is that mixing/induction of room air is limited, resulting in a very large throw length (up to 15 metres). The system also has a large penetration length, making it ideal for ventilating large areas. These features also make this system very suitable for delivering warm air. See datasheets 7 and 10 for further information.

KE-INJECT FLEX

The hole design for KE-Inject JET comprises 42 holes per row. There are no steps between the sections of holes. A typical feature of the KE-Inject JET System is that mixing/induction of room air is limited, resulting in a very large throw length (up to 15 metres). The system also has a large penetration length, making it ideal for ventilating large areas. These features also make this system very suitable for delivering warm air. See datasheets 7 and 10 for further information.
