Spot Heater High-Temperature Hot Air Heater

High-Temperature Electric Hot Air Heater


  • A high-temperature electric hot air heater capable of delivering hot air up to 800 °C.


  • Built with a pressure-resistant heater casing rated at approx. 490 kPa.
  • Spot Heater High-Temperature Hot Air Heater
  • SH02 Spot Heater High-Temperature Hot Air Heater
  • SH22 Spot Heater High-Temperature Hot Air Heater
  • SH31 Spot Heater High-Temperature Hot Air Heater


Spot Heater Overview

  • Maximum Continuous Operating Temperature: 800 °C
  • Heater Capacity: 0.55 kW to 3 kW
  • Equipped with
    • Sensor A: detects outlet air temperature
    • Sensor B: detects temperature for hot-start operation and overheat protection

      • → Enables precise and reliable temperature control

  • When used with the Multi-Controller TRC202,
    • Extends heater element life
    • Enables stable long-term operation at 800 °C
    • Improves hot-start operation, heater protection, and temperature control performance


    Note: One Multi-Controller TRC202 is required per Spot Heater unit.

    When the Multi-Controller is not used (e.g., when using a customer-provided temperature control circuit),
    the maximum hot air temperature is limited to 500 °C.
