SPG-6A-III Desktop High-Frequency Induction Heater for Rapid Melting of Small Metal Samples up to 100g
Operating within a frequency range of 600 to 1100 kHz, the SPG-6A-III delivers up to 6 kilowatts of power, enabling quick temperature ramp-up and controlled heating cycles. The system supports both automatic and manual timer controls, allowing users to set heating, dwell, and cooling times between 1 and 99 seconds for tailored thermal processing. Its design integrates both air cooling via a rear fan and water cooling with flow and pressure safeguards to maintain stable operation during extended use.
Key Features
- High-frequency induction heating from 600 to 1100 kHz for efficient energy transfer and rapid melting.
- Maximum output power of 6KW with adjustable input current (5-30 A) displayed digitally for precise control.
- Supports automatic timer control with programmable heating, dwell, and cooling intervals or manual operation via foot pedal.
- Integrated air cooling with rear fan and water cooling system requiring >3 L/min flow at ≥0.2 MPa pressure, with overpressure and over-temperature protection.
- Includes a standard induction coil made from 5mm diameter copper tubing (20mm diameter x 45mm height); custom coils available at additional cost.
- Duty cycle rated at 80%, with operational guidelines to prevent overheating by limiting induced current and enforcing rest periods.
- Compatible with tap water cooling, though use of a recirculating water chiller is recommended for optimal performance.

Typical Applications
This induction heater is suited for melting, sintering, annealing, heat treatment, and quenching of small metal samples in research laboratories, material science studies, and quality control environments. It is particularly useful for rapid thermal processing of alloys and metals where precise control of heating cycles is required.
Configuration & Operating Notes
The SPG-6A-III includes one standard copper induction coil. Custom coils can be ordered separately to accommodate specific sample sizes or shapes. The unit requires a stable single-phase power supply within the specified voltage range and a water cooling system with adequate flow and pressure. Tap water is acceptable, but a recirculating water chiller is recommended for consistent cooling performance.
To prevent overheating and ensure longevity, users should maintain induced current below 20 amps for continuous operation. If operating above 24 amps, a rest period of 2 seconds per 10 seconds of heating is necessary. The heater features automatic shutdown protection against over output conditions. Users should adjust sample size and heating parameters accordingly to avoid triggering this safety feature.
For melting applications, proper crucible setup and refractory insulation are critical for efficient heating and temperature control. Users are advised to consult with technical support regarding material melting points, alloy composition, and sample quantities to optimize process parameters.
