Twin-Tube Infrared Lamps
Custom and replacement twin-tube quartz infrared lamps for long heating zones, industrial dryers, production equipment and applications requiring stable multi-channel construction.
What makes a twin-tube infrared lamp different?
A twin-tube infrared lamp uses a quartz profile with two parallel internal channels. Depending on the design, the channels can hold heating elements, electrical connections or separate power sections.
The wider twin-tube profile can provide greater mechanical rigidity than a comparable single quartz tube, making this construction useful for longer lamps and industrial equipment.
Twin-tube describes the quartz construction rather than a specific wavelength. Short-wave, medium-wave, fast-response medium-wave and carbon heating technologies may all use a twin-tube format.

Twin-tube construction is frequently selected where lamp length, mechanical stability, heating-zone control or industrial installation requirements make a single tube less suitable.
Mechanical Stability
The wider profile can provide improved rigidity for longer lamps and demanding industrial installations.
Heating-Zone Flexibility
Active sections, cold zones and separate circuits can be arranged according to the machine design.
High Output Potential
Twin-tube profiles are commonly used in industrial lamps requiring substantial output over a long heating area.
Installation Options
Ceramic ends, clips, wires, terminals and reflector direction can be matched to the equipment.
One quartz profile can support different infrared emitter families
The correct heating technology depends on the material, required response speed and production process.

View carbon lamps →Custom heated zones and power distribution
Twin-tube lamps can be designed with different active sections, cold zones and electrical circuits. A dimensioned drawing is recommended for multi-zone production.

One active heating section across the required process width.
Two Divided Heating Zones
Separate active sections with a central unheated area.
Multiple Power Sections
Different lamp sections can be arranged for equipment requiring varied energy distribution across the width.
Control the direction of infrared energy
Reflector material, coating length and installation direction should be confirmed before production.
Gold Reflector
Metallic reflector coverage helps direct infrared energy toward the selected side of the lamp.
White Reflector
White ceramic reflector construction is used for selected custom and replacement infrared lamp designs.
Clear Quartz
A clear lamp emits infrared energy more broadly around the quartz profile rather than concentrating it on one side.
Twin-tube lamps matched to different machines and installation methods
Final construction depends on the electrical rating, overall length, quartz profile, reflector, terminals and support method.

A complete specification should include both electrical values and the physical twin-tube construction.
| Parameter | What to Confirm | Why It Matters | Recommended Reference |
|---|---|---|---|
| Voltage & Wattage | Electrical rating of the complete lamp or individual circuits | Must match the machine supply and control system | Lamp marking, drawing or equipment documentation |
| Overall Length | Complete lamp length including end construction | Determines whether the lamp fits the equipment | Dimensioned drawing or measured old lamp |
| Heated Length | Active area, cold zones and divided sections | Controls the location and width of infrared output | Heating-zone drawing |
| Twin-Tube Cross-Section | Quartz profile width and height | Must fit supports, clips and available installation space | Caliper measurement or technical drawing |
| Reflector | Material, coverage, length and direction | Affects the direction of infrared energy | Photographs showing the coated side |
| Electrical Circuits | Single circuit, separate circuits or multiple power zones | Determines control and wiring arrangement | Wiring diagram or photographs of terminals |
| Ceramic Ends | Shape, dimensions, hole positions and mounting method | Important for mechanical installation | Close-up photographs and measurements |
| Terminals & Wires | Terminal type, wire length, insulation and direction | Determines electrical connection compatibility | Photographs of both ends |

Match more than voltage and wattage
Twin-tube replacement lamps must match the mechanical installation as well as the electrical rating. Small differences in the quartz profile, ceramic ends, reflector or terminal direction can prevent correct installation.

Twin-tube infrared lamp construction and replacement
What is a twin-tube infrared lamp?
A twin-tube infrared lamp uses a quartz profile containing two parallel internal channels. Depending on the design, the channels can contain heating elements, separate circuits or other internal components.
Is twin-tube a type of wavelength?
No. Twin-tube describes the quartz construction. Short-wave, medium-wave, fast-response medium-wave and carbon infrared lamps can all use twin-tube profiles.
What is the difference between twin-tube and single-tube lamps?
A single-tube lamp uses one round or shaped quartz tube, while a twin-tube lamp uses a wider profile with two channels. Twin-tube construction is frequently selected for longer lamps, higher output or mechanically demanding installations.
Can twin-tube lamps have separate heating zones?
Yes. Depending on the design, active heating areas, cold zones and separate electrical circuits can be arranged. A dimensioned drawing is recommended.
Can twin-tube lamps be supplied with gold or white reflectors?
Yes. Clear quartz, gold reflector and white reflector constructions can be reviewed. Reflector length, coverage and direction must be confirmed.
What dimensions are required for a replacement twin-tube lamp?
Important dimensions include overall length, heated length, cold zones, quartz-profile width and height, ceramic ends, terminal position and lead-wire length.
Can you produce a lamp from an old sample?
An old lamp can provide a useful construction reference. Voltage, wattage, machine information, reflector direction and important dimensions should still be confirmed.
Are twin-tube lamps suitable for long industrial dryers?
Twin-tube construction is commonly considered for long heating zones, industrial dryers, ovens and conveyor systems. Final suitability depends on dimensions, power, supports, operating position and process conditions.
