Features:Enables high-temperature feeding and instant outflow of high-temperature solutions.

  1. Temperature Performance:
    • Control accuracy: ±1℃
    • Furnace temperature uniformity: ±1℃ (varies with the size of the heating chamber).
  2. User-Friendly & Intelligent Operation:
    • Easy to operate with programmable functions, including PID self-tuning, automatic heating, automatic heat preservation, and automatic cooling—no need for manual supervision.
    • Optional computer communication function allows operation via computer (e.g., starting/stopping the furnace, pausing heating, setting heating curves, storing heating curves, viewing historical curves, etc.). Free software is available; for details, refer to: Computer Control System.
  3. Rapid Heating: Adjustable heating rate from 1℃/h to 40℃/min.
  4. Energy Efficiency: The furnace chamber is made of imported fiber materials, featuring high temperature resistance and resistance to rapid temperature changes.
  5. Crucible Material: High-purity zirconium quartz.
  6. Furnace Body: Finely powder-coated for corrosion and acid/alkali resistance. With air cooling for isolation between the furnace body and chamber, the furnace wall temperature is close to room temperature.
  7. Dual-Loop Protection: Protects against over-temperature, over-pressure, over-current, thermocouple breakage, power failure, etc.
  8. Furnace Chamber Material: Imported refractory materials with excellent thermal insulation, high temperature resistance, and resistance to rapid temperature changes.

List of Optional Additional Functions

NameFunction IntroductionOptionsFunction Code
Temperature ControllerStandard 50-segment heating curve; imported instruments can be selected alternatively (B)Two choicesAB
TouchscreenChinese menu, storage of multiple heating process curves, storage of historical curves and data reports (7-inch)Four choicesC
IoT InterfaceThe RS485 communication interface of the electric furnace reads and writes real-time data such as furnace start, pause, stop, heating curve, allowable time, etc.D
Computer Control Software and HardwareThe furnace can be controlled via computer for starting, pausing, stopping, setting heating curves, reading heating curves, and parameter adjustment with high reliability and easy operation. It displays measured value, set value, output value, segment time, segment number, heating curve, and power percentage curve. Heating curves can be stored, set values and common parameters modified via computer. Historical curves and reports can be saved for a long time with selectable time intervals (1s-1h).E
PLCAdopts Siemens PLC control (capable of reading and writing furnace start, pause, stop, heating curve, time, temperature curve, atmosphere, flow, switch quantity, power supply, power); opens ports for serial and parallel data with upstream and downstream equipmentF
