Introduction
We built this shortwave infrared halogen lamp for one reason and one reason only: to dry bottle decorations without wrecking the color. It sounds simple, but the real challenge is balancing two things that don’t want to play nice together. You need to zap the moisture away fast, but you can’t cook the coating’s chemistry in the process. So we designed a heat profile that’s laser-focused—it goes straight after the water, not the pigment.
What’s Under the Hood
This is a shortwave infrared tube, running at 2500W and 400V. That voltage was chosen to pack a serious punch of heat into a small footprint. At 300mm long, it gives you a tight, focused hot zone. That means the heat lands right where the bottle passes, instead of wasting energy warming the air around it. Because the infrared energy hits the moisture directly, you’re not fighting a slow convection oven. You’re just getting it done.
The Build That Keeps It Honest
The tube sits inside a quartz envelope, filled with halogen gas. That combo keeps the filament stable even when things get seriously hot, so you get steady performance for thousands of hours. We also shaped the spectral output with a special coating, filtering out the wavelengths that can degrade pigment. And the R7s base? It’s the industry standard for a reason. It handles the high current and makes the lamp a simple, drop-in replacement. No rewiring. No custom fixtures.
On the Line, Where It Counts
On a bottle decoration line, you need drying that’s fast and under control. This lamp hits the water, evaporates it, and then pulls back before the bottle itself overheats. The payoff is a process that stays steady: the coating keeps its true color, and you’re using the least energy possible to get the job done. Just be real about one thing: 2500W at 400V puts out a lot of heat density. Your machine’s cooling system needs to be ready for the temperature rise. If you’ve got that covered, you get a repeatable, low-energy drying step that protects the finish and keeps the line moving.
