Twin Tube Short Wave Infrared Heaters
Short-Wave Twin-Tube Infrared Heaters – Brief Overview
Short-wave twin-tube infrared heaters are industrial heating elements that emit infrared radiation in the short-wave spectrum (0.78–1.4 µm) using a twin quartz tube structure.
Key Features:
- Twin-Tube Design:
Two fused quartz tubes arranged side by side, increasing mechanical strength and allowing longer span lengths without additional support. - Short-Wave Infrared Output:
Uses tungsten filaments heated to ~2,200°C, producing intense, deep-penetrating IR heat. Ideal for fast response times (less than 1 second). - Directional Heating:
Often includes a reflective coating (gold or ceramic) inside one tube to focus heat in a single direction, improving efficiency. - Fast Response & High Power Density:
Power densities up to 100 kW/m², enabling rapid heat-up and cooldown — excellent for dynamic or high-speed processes.
Advantages:
- Instant on/off capability
- Uniform and controlled heating over wide areas
- Durable design for long heater lengths without sagging
- Energy-efficient due to focused and rapid heating
Common Applications:
- Paint and coating drying/curing
- Plastic forming (e.g., PET bottle preheating)
- Textile and paper drying
- Electronics manufacturing
- Automotive and glass industries
