Speed control
EC speed control Control unit for EC fan
Temperature-dependent speed control for EC fan-and-filter units to reduce noise and save energy.
EC speed control Sensor for speed control
NTC sensor for temperature-dependent speed control of EC fans to reduce noise and save energy.
Speed control For fan-and-filter units and air/air heat exchangers
Temperature-dependent speed control to minimise noise and save energy in part-load operation.
