Certified indoor climate for the buildings of the future
KE Low Impulse
We offer the KE Low Impulse system in the form of round air bags (Ø)
Horizontal low-impulse systems
The air distribution principle of horizontal low-impulse systems is based on passive thermal displacement, in which the air is blown in with a subtemperature relative to the room air. Due to the density difference (the cooled air is heavier than the warmer room air), the room air is displaced under the duct, and the intake air continues with the direction towards the floor.

The air distribution principle for horizontal low-impulse systems
KE Fibertec's textile-based low-impulse systems are woven from fire-retardant polyester yarns, and the textile surface acts as a fine-meshed wire mesh, with the intake air seeping through the surface at a very low, uniform blowing speed of normally below 0.1 m/s. If the air is to be distributed according to the low impulse principle, the blowing speed should be kept below 0.40-0.50 m/s. This is the limit for when initial entrainment and mixing of room air in the low pulse flow will occur.

What is comfort ventilation?
Comfort ventilation is a general term for ventilation in premises with requirements for comfort (temperature, air speed, relative humidity, air quality, etc.).
Where is it optimal to use the KE Low Impulse system?
Textile ducts are particularly suitable for efficient, uniform and draft-free distribution of fresh air in all comfort environments and laboratories, but can also be used in industrial construction and the food industry.
What is Delta T (ΔT)?
It's the difference between intake temperature and room temperature. If a room in a cooling situation has a ΔT of, for example, -3°C, then the room temperature is 24 °C and the intake temperature is 21 °C.
What are CO2 and ppm?
Carbon dioxide (CO! 2) are wastes that are formed in the process of human combustion. It is a greenhouse gas which, when concentrated in the air, can cause people in the room to become drowsy, have headaches or perform work at lower levels of activity. Man is the largest source of developing carbon dioxide.
What is displacement ventilation?
In displacement ventilation, the intake air at the floor is supplied directly into the living zone, thus creating a layered flow in which the cooled intake air flows into the room under the warmer room air.
