Getting Your Adelco Drying Tunnels to Actually Behave
If you’ve ever run a long tunnel oven, you know the struggle. Trying to keep a steady heat flux across a massive surface area is a nightmare. Most people just throw in standard quartz tubes, but here’s the problem: they waste a ton of energy heating up the air and the oven walls instead of the actual product. That’s why we use shortwave IR reflector lamps. Instead of letting the heat wander, the reflector pushes that energy forward, right into the ink where it belongs. The fight against “skinning” To get a long conveyor up to temp, you need some serious power per millimeter. We build these lamps to handle the voltage drops that always seem to happen in long industrial circuits. The goal is to get the heat to penetrate the ink surface fast. If you don’t, you get “skinning”—that annoying situation where the top layer dries instantly and traps all the solvents underneath. Nobody wants that. It’s all in the mirror The reflector isn’t just a piece of shiny metal. We use gold-plating or high-purity aluminum because they’re way better at bouncing shortwave light. The best part? This lets you move the lamp further away from the product. You don’t have to worry about scorching your substrate, and you get a much smoother, more even heat across the whole web. Making it work in the real world We designed these to be drop-in replacements for Adelco footprints. We use standard industrial connectors, too, so when you’re in the middle of a maintenance shutdown and every minute counts, you can get them wired up and moving quickly. One heads-up, though. These lamps put out a lot of heat at the back of the housing. If your ventilation is clogged or just too weak, the end caps will overheat and your lamp life will tank. Keep your airflow clear. It’s the simplest way to make sure your tubes don’t burn out way before they should.
