halogen quartz tube infrared heater

May 6, 2026

We build halogen quartz tube infrared heaters for the places where space is at a premium and the heat has to show up—no excuses. These aren’t your everyday, do-a-little-bit-of-everything heaters. They’re compact powerhouses, built to throw focused energy exactly where you need it. If your day is all about curing, shrinking, or preheating—fast—this is the tool you reach for.

Power, voltage, and shape: the details that matter

Here’s the thing about these heaters: they’re all about power density. Take a 2500W output packed into a 300mm tube, for instance. That gives you a high watt-density profile, so you can heat a small target area quickly without blowing up the whole system. And that 400V requirement? It’s chosen to deliver that power while keeping the current draw in check. Lower current means smaller wiring and smaller contactors in your control panel, so your electrical footprint stays tidy. Dimensions matter, too. A 300mm length paired with a 10mm diameter tube gives you a predictable thermal footprint. That geometry lets you nail your reflector setup and focal point with precision, so the heat lands exactly where the process needs it.

Materials and design: built to stay clean and respond fast

Inside the quartz envelope, the halogen cycle keeps the filament clean, even at scorching temperatures. That means stable output over the lamp’s life—no annoying blackening like you get with standard incandescents. The quartz tube itself is great at transmitting shortwave infrared, so response is quick. On and off in seconds. For the base, the R7s is the standard for linear double-ended lamps. It gives you solid electrical contact and solid mechanical retention in fixtures, and it makes replacement a straightforward drop-in job. And if you want to save time in the field, the SK15 connector gives you a quick-connect option for wiring—easy during install, easy during maintenance.

Where they shine: speed, control, and reliability

These heaters really come alive in applications like PET blowing, plastic welding, coating curing, and packaging sealing. The shortwave output hits surfaces fast, raising temperature without wasting time heating the surrounding air. That direct energy transfer speeds up cycle times and cuts down on wasted energy. Because they respond so quickly, you get tight control over the heating profile—exactly what you need when you’re running high-speed lines. Now, the trade-off is heat density. The high watt density means you have to manage heat properly. Your machine needs to be designed to pull that excess heat away, or you risk overheating nearby components. Get the heater spec right, get the cooling spec right, and the system runs reliably—day after day.
