Spot Heater (800 °C Specification)

High-Temperature Electric Hot Air Heater


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


  • Built with a pressure-resistant heater casing rated at approx. 490 kPa.


Spot Heater Overview

  • Maximum continuous operating temperature:800 °C
  • Heater capacity: 0.55 kW to 3 kW
  • Equipped with
    • Sensor A: detects hot-air outlet temperature
    • Sensor B: detects hot-start temperature & prevents overheating

      • → Ensures precise and reliable temperature management

  • When used with the Multi-Controller TRC202,
    • Heater element life is extended
    • Enables stable long-duration 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-made control circuit),
    the maximum hot-air temperature is limited to 500 °C.
