Carbon Fiber Twin Tube Medium Wave Infrared Heater (Heavy Duty)

For large-scale industrial drying tunnels and continuous processing lines, achieving absolute surface temperature uniformity across massive areas is a persistent engineering challenge. The Hongtai Carbon fiber twin tube infrared heater is built specifically to conquer this.

By combining the gentle, deep-penetrating thermal characteristics of woven carbon fiber with the extreme structural rigidity of a fused double-tube quartz profile (15x33mm), we have created the ultimate heavy-duty Medium wave panel heater. Operating in the 2.0 – 3.5 μm wavelength range, this emitter is perfectly tuned for evaporating moisture from dense materials and curing heavy polymer coatings without causing surface micro-cracking or blistering.

1. The Superiority of the Carbon Twin Tube

Standard single-tube carbon heaters are effective, but they lack the mechanical strength required for very wide conveyor systems. The Double tube carbon heater utilizes a robust 15x33mm quartz cross-section, which houses two independent carbon fiber bundles.

This provides two critical advantages:

• Mechanical Rigidity: The “Figure-8” twin tube design resists bending and thermal warping over long spans, allowing you to build wider drying tunnels without internal support struts that cause cold spots.

• Thermal Uniformity: The parallel carbon filaments emit a broad, continuous band of infrared energy. When mounted sequentially, they act as a flawless, uniform heating ceiling, making them indispensable for processes highly sensitive to temperature gradients, such as wood veneer drying or automotive clear-coat curing.

2. Extreme Wiring Flexibility (A/B/C/D Configurations)

Machine builders require flexibility in control cabinet design. Our Carbon fiber twin tube is manufactured with fully customizable wiring topologies to match your specific PLC zoning requirements:

• Type A (Single-Ended, Series): Both wires exit one side. Filaments are connected internally in series. Ideal for high voltage, low current setups.

• Type B (Single-Ended, Parallel): Both wires exit one side. Filaments run in parallel. Perfect for standard voltages with maximum wattage output.

• Type C (Double-Ended, Parallel): Wires exit opposite ends, running parallel.

• Type D (Independent Channels): 4 wires total (2 per side). Allows your PLC to control the front and back tubes independently, effectively giving you dual-zone control within a single quartz casing.

4. Target Industrial Applications

This Medium wave panel heater is the heavy-lifting component for large-format manufacturing:

• Wood & Furniture Processing: Drying moisture from timber, and curing lacquers, varnishes, and edge-banding glues without warping the wood substrate.

• Large Drying Tunnels: Automotive paint baking rooms and powder coating lines where consistent, wide-area heat distribution is non-negotiable.

• Glass Manufacturing: Pre-heating and drying screen-printed ceramic frits on architectural glass panels.

• Paper & Corrugated Board: Deep moisture removal in thick, multi-layer paper manufacturing.

5. Frequently Asked Questions (FAQ)

Q: Can these heaters be mounted vertically?

A: Yes. Unlike tungsten-halogen lamps that require horizontal mounting to prevent filament sag, the carbon fiber bundles inside our Double tube carbon heater are structurally stable and can be mounted vertically, diagonally, or horizontally without any risk of internal short circuits.

Q: Why choose the 15x33mm size over the 11x23mm?

A: Carbon fiber filaments are physically thicker than tungsten wires. The larger 15x33mm quartz envelope ensures adequate internal clearance for the high-power carbon bundles, preventing localized overheating of the glass while maximizing power output (up to 4500W).
