Jet Air Heaters
The JET provides a compact and efficient heater solution for air temperatures up to 1400°F (760°C). Available in a 3.0kW or 8.0kW, 240V 1ø unit, the Jet offers two type “K” thermocouples with a convenient terminal block for easy wiring. To ensure safety, power and perfect control, connect with the optional Jet Control Panel. Each heater has a convenient method for mounting the housing and offers a ground stud located at the inlet of the heater. Air is commonly supplied by compressed or regenerative air.
- All-purpose Single Phase Heater
- (2) Built-in Type K Thermal Couples
- Built-in Over-temp Protection
- Single Phase
- Temperatures are measured by internal "K" thermal couple sensors locationed inside the SureHeat Jet housing.
- Use of other sensor types and/or locations can result inheater damage
- Minimum air flow for accurate control is 2 SCFM
- Maximum air temperature in 1400°F (760°C)
- Operating above temperature voids the product warranty.

- Bending / Forming
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)
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.
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
