Example of use:
For example, VD T120 roof fans are ideal for use in production halls with welding robots and machines. VD T120 ensures permanent basic ventilation. When robots and machines are in operation and generate waste heat, the room temperature sensor LTR registers the increase in hot air and sends a signal to the electronic temperature controller ETR. The fan volume flow is increased accordingly in conjunction with the frequency inverter FU-CS.
