If your greenhouse is equipped with recirculation fans, it is important that these fans run at the correct number of revolutions per minute or speed. In order to regulate the speed of your recirculation fans, we offer speed controllers. The speed controllers can control several recirculation fans at the same time, the number depends on the power consumption of the fan. The speed is determined manually on the speed controller itself or by the climate computer that controls the speed controller.
Our used speed controlers are fully technically inspected and delivered under warranty.
