Control an Air curtain

Air curtains create an invisible barrier to separate hot and cold air. Air curtains can also be used to prevent air or contaminants from moving from one room to another. Air curtains can be activated manually or automatically, based on temperature difference. In case of manual air curtain control, the air velocity can be adjusted via a switch or potentiometer. This can be done locally or remotely. For automatic air curtain control, temperature sensors measure the difference between inside and outside temperature and activate the air curtain if necessary.

Industrial air curtain controller | single-phase motors 10 A

5-speed controller for air curtains with single-phase motors. The combined maximum motor current is 10 A. The air velocity can be selected via the 5-step rotary switch. In OFF position (zero), the motor is disabled. The TK monitoring function deactivates the motor in case of overheating. The digital input can be used for remote start-stop commands. After a power failure, the motor automatically restarts. The autotransformer technology generates a motor voltage with a perfect sinusoidal shape. This guarantees quiet motor operation. Only for voltage controllable motors.
