The preheating glass twin quartz heating tube is designed for industrial infrared heating applications requiring fast response times and high efficiency. This specialized heating element achieves operating temperatures ranging from 1000°F (537°C) to 2000°F (1093°C) with remarkably quick heat-up and cool-down cycles.

Key features include nearly instantaneous heating capability (reaching optimal temperature in 4-6 seconds), 94% energy efficiency that can provide up to 25% operational savings, and an extended service life exceeding 5000 hours. The gold coating on the heater surface effectively doubles the radiation output, while the optimized reflection from the back-mounted gold reflector enhances overall performance.

These quartz heating tubes are available in standard horizontal operation configurations, with modifications possible for vertical applications. Customers can choose between one-side or two-side connection designs to suit specific installation requirements. The compact design delivers high radiation density up to 150 kW/m² (100W/in²) output in minimal space.

The filament operates at extremely high temperatures between 1800-2200°C, providing excellent radiation penetration depth into processed materials. The infinitely adjustable, rapid-reaction control system allows for precise temperature management in various industrial processes.
For specialized applications, we offer custom and OEM configurations with flexible specifications including different diameters, lengths, power ratings, and voltage requirements. The quartz tubes are CE certified and backed by a 1-year warranty.
