Twin Tube IR Lamps offer a versatile alternative to standard single tube lamps. In addition to allowing more watts per inch as compared to single tube lamps (making it possible to attain higher temperatures in a shorter time), twin tubes allow you to make the most out of particular physical constraints.

The design of twin tube lamps makes them mechanically stronger than single tube lamps. The strength is most important when the lamps are longer than 600 mm. When single tube lamps are long they can bow in the middle, stressing the quartz tube. Twin Tube lamps are available in lengths up to 4 meters.

Lead and filament placement can be customized to fit the needs of a particular process (see chart). For example, having both leads on
one side (examples A,B,E,G,K, & L) offers a space saving advantage, in instances where electrical/physical access to both sides of the machine may be inconvenient.

Twin tube lamps have many standard wattages and voltages to meet the need for direct replacements for lamps used in existing equipment. Gold or ceramic reflective coatings can be applied to focus the emitted energy, increasing the thermal efficiency.

In some specialized circumstances, twin tubes may even be used to cool the heating element, by running an element down one tube, and water cooling in the other.
