Comfort
Good ventilation is the key to fresh air, optimum temperature and a comfortable indoor climate without drafts or noise
Comfort that makes a difference
KE Fibertec defines comfort where people in sedentary environments do not experience drafts. This is achieved by the fact that the air velocity in the occupied zone does not exceed imperial.
The air distribution principle of low-impulse systems is based on passive thermal displacement, in which the air is supplied at a lower temperature than the air in the room. Due to the difference in density, where the cooled air is heavier than the warmer air in the room, the room air is displaced under the duct, while the blown air continues to move towards the floor. Air flow in space is then based on natural air movements, where the air is driven by the difference in density and convection currents from heat-giving activities and processes, hence the term “passive thermal displacement”.
Another option to achieve comfort is hybrid systems, which are low impulse ducts, with laser-cut holes. As a result, the low-impulse principle is combined with the high-impulse principle, whereby part of the volume of air in the system is distributed away from the nearest zone under the ducts. This offers obvious advantages in particular if cooling is required where deltaT is higher than imperial, as it helps to avoid an immediate “cold drop” under the ducts. The cooling load is instead distributed over a larger area of the room.
Controlled air for laboratories
A solution from KE Fibertec can efficiently handle large volumes of air without drafts, making the system ideal for laboratories with stink cabinets and high air exchange.
The KE Fibertec solution works quietly, creating a comfortable working environment without disturbing sound. It ensures high comfort, concentration and well-being for everyone staying in the room, while ensuring the efficient operation of ventilation.
For laboratories with clean room requirements, the air can be supplied in Multiweave material, which does not emit fibers and is therefore approved for use down to Cleanroom Class 4.
Comfort and sound environment in cinemas, theaters and recording studios
Ventilation air is supplied at low speeds in the occupied zone, so guests and employees experience a comfortable, quiet air flow.
Low CO2 levels are achieved with the efficient distribution of fresh air and stable temperatures without compromising acoustics or room dynamics.
Draft-free air in schools and offices
Fresh air is essential for efficiency in both the classroom and the office. Students and employees' performance ability decreases with increasing CO2 levels. When CO2 levels rise from 1000 ppm to 1225 ppm, performance drops 5% and at 1600 ppm a decrease of 10%.
The same applies to the temperature in the room. Performance ability of students and employee's decreases with increasing temperatures. When temperature rises from imperial performance decreases by 5% and 10% when temperature rises to imperial.
The KE Fibertec system is easy to install and can be placed in the room so that the optimum air distribution is achieved.

By adding the air directly in the occupied zone, efficient heating and cooling is achieved without supply air volumes. It can reduce the energy consumption of the cooling and heating system by up to 30% and at the same time minimize the need for expensive steel ductwork.
A textile-based ventilation system is lighter both in the weight of the material and when assembled. This means significantly shorter assembly time - up to 9 times faster. It also requires less energy to achieve the same design criteria. With the savings in material , labor, not having to insulate or paint, it provides significantly lower operating and construction costs over traditional steel solutions.
The nozzles limit the induction of room air, so the air loses speed slower. The result is greater throw length and deeper thermal penetration, securing that both hot and cold air are accurately distributed throughout the space.
The hybrid solution combines air-permeable fabrics with KE-Direjet nozzles. It prevents condensation and dust on the ducts and ensures that both hot and cold air can be distributed efficiently and comfortably in the room.
