A Line of Industrial Control Solutions from the Heating Experts
TUTCO’s depth of expertise uniquely qualifies us to manufacture control panels for the heaters we produce, as reflected in our unwavering commitment to quality. Our engineers have leveraged the latest technology in heater controls and safety features to create a line of totally customizable controllers well-suited for industrial facilities and OEMs. Our controllers utilize power controllers, temperature controllers, and thermocouples to continuously monitor and maintain consistent output voltages to the heater.
Regardless of fluctuations in the process or changes in airflow, the temperature is continually monitored to meet process requirements and safeguard the heater. Each controller features LAN connectivity via an RJ45 port, which allows the controller to communicate and retrieve data from a remote HMI or another external device, such as a data logger or webpage.
Closed-Loop (Feedback) Control
Closed-loop heater control systems use a power controller, temperature controller, and thermocouple to monitor and maintain a constant output temperature, regardless of changes in airflow. The typical temperature controller provides a convenient display of the air temperature (not the element temperature).
Temperature Controller
- Use only digital temperature controllers with Type K thermocouple inputs.
- The temperature control output must match the input of the power controller (e.g., 4–20 mA or 0–10 VDC).
- A standard PID-type control with a wide proportional band works best to minimize temperature overshoot.
- PID parameters may be auto-tuned, but only at temperatures below the maximum rating of the heater. Monitor the heater temperature rise and turn power off immediately if it exceeds the heater’s specification during the auto-tune cycle.
Power Controller
SCR (Silicon Controlled Rectifier) power controllers provide the smoothest power regulation for electric air heaters. Power controllers, such as SSR (Solid State Relays) or other fast-switching controllers are also used with our heaters. Contact TUTCO SureHeat for details.
