Steam vs. Infrared: Is it actually worth the switch?
If you’re still using steam to dry your wood coatings, you know the drill. You’re basically heating up the entire room just to get the wood warm. It’s slow. It’s clunky. And honestly? You’re paying to heat your warehouse walls, not your product. Giardina infrared (IR) lamps handle things differently. Instead of warming the air, they shoot energy straight into the coating. It’s a direct hit. The shift in how you work Think about your current setup. You’ve got those massive boilers, endless piping, and the constant need to vent. It’s a lot of hardware to baby. With IR, we just wire the lamps right into the line. That’s it. You flip a switch and you have heat. No more standing around for two hours waiting for a boiler to get up to temp before the first board even touches the belt. That wasted startup time just… disappears. Winning back your floor space This is the part that usually gets people excited. Steam tunnels are long because the heat moves so sluggishly. IR is fast. Like, really fast. Because of that, you can usually chop your drying zone down by 50% or even 70%. Imagine what you could do with all that extra room. Maybe another CNC machine? Or just a bit more breathing room for your assembly team? Plus, the money side of things starts to make sense pretty quickly. Your utility bills drop. You stop spending hours maintaining a temperamental boiler. And your line moves faster. The “catch” (because there’s always one) Now, IR isn’t some magic wand. Steam is gentle—it’s a slow soak. IR is intense. If you crank the lamps too high or let the conveyor crawl too slowly, you’re going to have problems. You might scorch the wood or deal with “skinning,” where the top dries too fast and traps solvents underneath. It’s all about finding that sweet spot between the wattage and how far the lamp sits from the piece. It’s a pretty easy swap for your drying stage, but you’ll want to tweak your line speed to keep up with how quickly things cure. Once you dial that in, you’re golden.
