Introduction
We build transformers for one very specific job: powering quartz infrared halogen heaters. These aren’t your typical light bulbs. They’re industrial workhorses—built to throw out intense, focused heat when you need it, fast. The transformer is the bridge between your plant’s power and the lamp’s exact needs, so the heater does exactly what it’s supposed to do, without fuss.
Power, Voltage, and Size: Getting It Right
Halogen heaters are picky about power. A common industrial setup, for example, runs at 400V and 2500W. That high voltage keeps the current lower, which cuts down on line losses and keeps the wiring from feeling like it’s fighting you. Wattage is what gives you heat density. Push 2500W into a 300mm tube and you get a tight, concentrated blast of heat—perfect for spot heating. But it also means your electrical system feels the load. You’ve got to match the transformer and wiring to that power draw. If you undersize, you get voltage drop and the lamp just won’t perform the way it should.
The Core: Why Quartz Makes a Difference
The tube isn’t glass—it’s quartz. Quartz can handle the shock of rapid on/off cycling and stays strong even above 800°C. Inside, a halogen cycle keeps the filament stable. It takes evaporated tungsten and redeposits it back onto the filament, so the lamp doesn’t go dim the way standard incandescent bulbs do. That cycle is what keeps output steady over the life of the lamp. And the R7s connector? It’s the standard because it can take the heat right at the terminals, giving you a secure, low-resistance connection that won’t loosen as things heat up and cool down.
Where It Shines—and What to Watch For
These systems are made for processes that need fast, localized heat: plastic welding, PET blowing, curing coatings. The 300mm length gives you a focused heating zone, and the high wattage means you get rapid temperature ramp-up. The payoff is speed and control. The trade-off is heat density. A 2500W halogen lamp throws off a lot of ambient heat. Your equipment needs proper cooling and shielding. If you don’t manage the surrounding temperature, the transformer and nearby parts will run hot—and that shortens service life. Plan for airflow and give everything enough mounting distance.
