Advanced fan speed control - TK monitoring - gas flow control
SFPR1 series are transformer fan speed controllers with an output to control a gas valve. An air flow sensor or pressure relay is required to detect the gas flow. The output is activated simultaneously with the fan. In case air flow is not detected within 60 seconds after the motor is started, the gas valve output is deactivated. Local safety regulations often dictate that gas can only be supplied after the kitchen hood exhaust fan above the stove has been activated. This makes the SFPR1 series the ideal fan speed controller for industrial kitchen hoods! Their TK monitoring function protects the motor against overheating. They control single phase voltage controllable motors up to 13 A. After a power failure, the motor will automatically restart.
