Gold Reflector Short Wave Twin Tube Infrared Heater (High Power)

When industrial processes require massive thermal energy delivered over long physical spans, standard single-tube heaters often fall short due to structural limitations. The Hongtai Twin tube infrared heater is engineered specifically to solve the dual challenges of high-power density and mechanical sagging. Utilizing a specialized “8-shape” cross-section, this emitter combines two high-purity quartz tubes into one rigid, fused structure.

This Double tube quartz heater is the ultimate high-performance thermal engine for demanding sectors such as metallurgy, glass tempering, and wide-web laminating. Coupled with a highly efficient pure gold reflector, this 8-shape infrared lamp directs 95% of its radiant energy exactly where it is needed, achieving astonishing power densities of up to 150-200 W/cm while spanning free lengths up to 3000mm.

1. The 8-Shape Structural Advantage

In long-span industrial ovens (such as those used for steel strip heating or glass tempering), standard round quartz tubes tend to sag or bow under their own weight at high temperatures.

The 8-shape infrared lamp design inherently provides exceptional mechanical stiffness and resistance to bending. By fusing two tubes together, the structural integrity is multiplied. This allows us to manufacture reliable, free-spanning heaters up to 3000mm (3 meters) in length without the need for complex internal supports that can shadow the radiation and complicate oven design.

Inside this robust casing, dual tungsten halogen filaments deliver extreme short-wave infrared heat, penetrating deeply and reacting to PLC control commands in less than a second.

2. Key Technical Features & Selling Points

• Extreme Power Density: Capable of delivering a staggering 150 to 200 Watts per centimeter of heated length. A single 3-meter unit can output up to 6000W, providing unparalleled thermal punch for heavy industry.

• Single-Ended Wiring Option: We can configure the Twin tube infrared heater so that both electrical connections exit from just one side (Single-Ended). This dramatically reduces wiring complexity, saves space in the control cabinet, and minimizes installation labor for OEMs.

• Customizable Gold Reflector: To maximize efficiency, a pure gold reflective coating is applied to the quartz. We offer bespoke customization: apply the gold to the A-Side (Waist/Center) to create a wider, diffused heat spread, or the B-Side (Back) for highly focused, directional spot heating.

• Instant Response: Short-wave tungsten filaments heat up and cool down in under 1 second, preventing product damage or fire hazards during unexpected line stoppages.

4. Heavy Industry Applications

The Double tube quartz heater is the trusted, heavy-duty solution for large-scale thermal processing:

• Metallurgy & Steel: Rapid heating of steel strips and metal coils prior to galvanizing, coating, or rolling processes.

• Glass Processing: Intensive pre-heating and drying in automotive and architectural glass tempering furnaces.

• Plastics & Composites: Curing fiberglass resins and laminating wide sheets of composite materials in continuous lines.

• Long-Span Industrial Ovens: Any conveyorized drying tunnel requiring wide heat coverage without the interference of intermediate supports.

5. Frequently Asked Questions (FAQ)

Q: Why do machine builders prefer Single-Ended wiring?

A: Single-ended wiring means both power cables exit from one side of the Twin tube infrared heater. This is highly preferred by OEMs because it allows all electrical busbars, wiring conduits, and cooling channels to be consolidated on one side of the machine, making maintenance significantly easier and reducing overall wiring costs.

Q: Which side should I put the gold reflector on?

A: It depends on your target. Coating the B-Side (the flat back) focuses the beam straight forward, ideal for narrow, fast-moving targets. Coating the A-Side (the indented waist) creates a slightly wider, more diffused radiation pattern, which is excellent for curing wide webs of paper, textiles, or steel.

Q: Can these withstand high vibration environments?

A: Yes, the fused twin-tube design is inherently more rigid and vibration-resistant than single tubes. However, for extreme vibration environments (like heavy stamping or metal cutting lines), we recommend mounting them with our specialized high-temperature spring-loaded clips to absorb mechanical shock.
