Max Air Heaters
Tutco SureHeat's Max air heater provides a compact and efficient heating solution for air temperatures up to 1400°F (760°C). Available in a 6.0kW to 36.0kW, 240V/380V/480V 1ø / 3ø units, the Max offers two type “K” thermocouples with a convenient terminal block for easy wiring. To ensure safety, power and perfect control, connect with the optional Max Control Panel. Each heater has a convenient method for mounting the housing and offers a ground stud located at the inlet of the heater.

Additional Info
Closed-Loop (Feedback) Control
Closed-loop heater control systems use a power controller, temperature controller and thermocouple to monitor and provide 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)
Power Controller
SCR (Silicon Controlled Rectifier) power controls will provide the smoothest power regulation for electric air heaters. Please contact Tutco SureHeat before using other power controllers, such as SSR (Solid State Relays) or other fast-switching controllers.
Temperature Controller
Use only digital temperature controls with Type K thermocouple inputs. The temperature control output must match the input of the power control (i.e., 4-20mA or 0-10VDC). A standard PID-type control with a wide proportional band setting will work best to minimize temperature overshoot. PID parameters may be auto-tuned, but only at temperature specifications below the maximum of the heater. Monitor the heater temperature rise and turn power off immediately if it rises above the heater specification during the auto-tune cycle. Thermocouple 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
