Nordic Evolution 120 without regulation

Silent ceiling fans intended for large rooms. A ceiling fan that circulates up to 1,700 m3 of air per hour. The hot air that seeks up under the roof can, with the help of the large air circulation, be forced down. This can be advantageously used in e.g. factory halls, warehouses, warehouses and other locations with high ceilings. The temperature of the warm air that rises to the sky rises by 1° per m with an ordinary thermometer you can easily check how big the temperature difference is between floor and ceiling.

With a ceiling fan installed, so much energy is often saved that the costs of the installation can be recovered within a year. To avoid too high an air speed (max. 0.2 m/s), the ceiling fans should be adjustable. The table below indicates how many m² a ceiling fan can handle at different heights. Example: An industrial premises of 700 m2 has a ceiling height of 5 m. A ceiling fan Ø 140 covers 60 m² at a ceiling height of 5 m. By dividing the area of 700 m² by the fan's capacity of 60 m², you arrive at a need for 12 units . (11.7) fans. Symmetrical placement of the fans is important.
