What Actually Matters: Power, Voltage, and Size
We make low-light infrared heaters for industrial machines—the kind of heat that does the job without blinding the people running the equipment. Most of the time, these are halogen tubes. They’re often rated at 400V and can hit 2500W. That high-voltage setup keeps the current down, which means you can use thinner wiring and smaller terminals without worrying about voltage drop. And the length? Typically around 300mm. It’s a tight footprint, built to squeeze into the cramped heating zones on blow molding and packaging machines. You get a lot of heat packed into a small space. But that also means your machine’s cooling system needs to be up to the task—otherwise, the ambient heat builds up fast.
The Inside Story: Halogen, Quartz, and the R7s Base
At the heart of these heaters is a quartz envelope, filled with halogen gas. That combo keeps the filament stable, stops the tube from blackening, and keeps the output steady—even during long production runs. The low-light part comes from a carefully tuned filament and reflector design. It pushes the energy into the infrared spectrum, so you get process heat with way less visible glare. Then there’s the R7s connector—a straight, two-contact base that can handle the high temperatures right at the ends of the tube. It makes replacement simple: swap it in and get back to work.
Where It Shines: Tight Spaces, Fast Heat-Up
In places like PET blowing and plastic welding, you need heat exactly where the part meets the tool—and you need it immediately. These low-light infrared heaters respond fast, delivering heat right where it counts. That cuts warm-up time and keeps the surrounding components cooler. And because the footprint is compact and the R7s mounting is straightforward, swapping out a burned-out tube is quick. Downtime stays short, and the line keeps moving.
