World’s First ─ Radiant Heat Recovery Demonstration at Steel Plant

As industries worldwide strive for energy efficiency and carbon neutrality, utilizing wasted thermal energy from high-temperature processes has remained a major challenge. Galaxy PCB has achieved a groundbreaking milestone by developing the world’s first commercial thermoelectric generator module (40W TGM) specifically designed for radiant heat recovery, successfully deployed at a steel plant demonstration site.

By capturing radiant heat from steel surfaces exceeding 900 °C, our modules convert waste heat directly into electricity and integrate with a mobile energy storage system, creating a complete recovery-to-application solution.
The current mobile demonstration system delivers 500W capacity, not only proving stable power generation but also enabling flexible storage and utilization of clean energy.

Key Highlights

• World’s First: The only commercial-grade TEG module engineered for radiant heat recovery.
• On-Site Conditions: Steel surface temperature > 900 °C (monitored by infrared thermography).
• Module Features: 40W TGM module integrated with aluminum heat sinks and water-cooling for efficient thermal management and stable output.
• System Integration: Combined with a mobile energy storage system, enabling instant storage and flexible energy deployment.
• Power Generation: Mobile demonstration system with 500W installed capacity.
• Future Potential: Applicable to steel, aluminum, glass, and cement industries, helping enterprises achieve energy savings, carbon reduction, and greater energy independence.

Outlook

The current 500W system is a mobile solution, ideal for testing, demonstration, and flexible deployment. Very soon, Galaxy PCB will launch a suspended (fixed) radiant heat recovery system, designed for long-term, stable integration into steel plants and other high-temperature industries.
