Industrial Heater Control Panels

CUSTOM UL508A Heater Control Panels & Accessories

Industrial heating control systems are critical for proper heater set-up and longer element life. Before turning the power on to any heater, it is essential to have the proper air flow through the heater. Only qualified professionals should install Tutco SureHeat air heaters and controllers. Follow all applicable electrical codes and proper wiring.  ​

Electric air heaters are merely components of a well balanced and long lasting system.  Without the proper control set up, electric coil heaters can prematurely fail due to overshoot from voltage control issues.  Thermal designed systems are not created equal.  The best way to ensure your heater element performs as expected is to purchase a packaged solutions from trusted experts.

Closed-Loop Controls diagram

Closed-Loop Controls Closed-loop heater control systems use a power controller, temperature controller and thermocouple to temperatures.

Temperature Controllers diagram

Temperature Controllers A standard PID-type control with a wide proportional band setting will work best to minimize temperature overshoot.

Thermocouple Placement

Use only a fine wire (0.030” max. wire diameter), exposed junction, Type K thermocouple placed within 1” of the heater exit for accurate temperature readings. Other thermocouple styles, or varying the distance from the heater exit, will result in temperature measurement errors and thus the potential for heater failure.

Power Controllers

SCR (Silicon Controlled Rectifier) power controls will provide the smoothest power regulation for Tutco SureHeat air heaters. Please contact Tutco SureHeat before using other power controllers, such as SSR (Solid State Relays) or other fast-switching controllers.
