DynamicAir
Dynamic Air is a new ventilation principle that ensures the producer improved minimum ventilation as well as optimised heating consumption. Dynamic Air (patent pending) is a new principle for online measuring of air output in air outlets.
High animal welfare - low heating costs
An accurate measurement of the output is particularly important in connection with minimum ventilation. Correct minimum ventilation is crucial for the productivity and the heating costs. Too low ventilation level will impact on the welfare of the animals and the productivity. However, too high ventilation level results in unnecessarily high heating costs.
No mechanical weaknesses
Today, a mechanical fan whell anemometer is the most common technique used to determine the airflow. However, a fan whell anemometer causes some resistance in the exhaust unit, which reduces the output of the unit.
A fan whell anemometer is also a mechanical construction located in a ‘harsh environment’ directly inside the exhaust unit. Over time, the fan whell anemometer will measure less accurately because of wear, and in the worst-case scenario, it will break. The Dynamic Air principle does not include the direct contact between fan whell anemometer and the measuring equipment which is the case for the fan whell anemometer. Therefore, the risk of wear and tear plus breakdown has been minimised.
Overall, the Dynamic Air concept offers a very precise determination of airflow without any use of mechanical, movable components, which makes it reliable and financially attractive and gives it long-term stability.
Areas of strong wind action
Heavy winds have always been the number one enemy of minimum ventilation. Strong winds make it difficult to maintain sufficient and constant minimum ventilation. The problem has been resolved by running the fan at a high number of revolutions and then regulating the ventilation level by means of flap opening.
The Dynamic Air measurements constantly make allowances for any pressure drop that may occur because the exhaust unit is exposed to too great wind impacts, and therefore the fan can be adjusted closer to the actual need. This is illustrated in the below video.
