Stop the Temperature Drift in Your Tunnel Ovens
If you’re running a long tunnel oven—like the Adelco drying lines—you already know that raw power isn’t everything. You can throw all the wattage in the world at a conveyor, but if the heat isn’t steady from start to finish, you’re in trouble. When your infrared lamps start drifting, you get uneven curing. And uneven curing means scrapped parts. It’s a headache nobody needs. That’s why we built our infrared solutions to slide right into EFI Reggiani and Adelco systems. We want to kill that variance before it kills your margins.
The Balancing Act: Voltage and Heat
Here’s the thing about long tunnels: it’s all about the balance between your voltage and the length of the tube. We use high-wattage quartz lamps because they provide the kind of heat density needed to keep your substrate at a rock-solid temperature. If you go with a high-voltage setup, you get a punchier, more concentrated energy output. It’s great for those fast-cure cycles where time is money. But there’s a catch. When you cram that much power into a small space, your cooling fans have to actually do their job. If the housing gets too hot, you’ll burn through your lamps way faster than you should.
Tough Glass and Simple Plugs
We use halogen-filled quartz glass. Why? Because we can tune the spectrum to match exactly what you’re drying. Plus, these lamps are built to take a beating. Industrial environments are messy and rough; your gear needs to handle it. We also stick to standard connectors, like R7s or Sk15. You can just wire them in without having to mess around with your existing loom. It’s simple. Plus, using the right connector stops arcing at the terminals—which is usually where things go sideways in high-vibration ovens.
No More Cold Spots
Nobody likes a cold spot. We make sure the lamp’s focal length matches the actual shape of your oven’s interior. This ensures the infrared energy hits the target directly instead of wasting heat on the oven walls. It’s a win-win. You put less strain on your power grid, and you get a stable thermal profile from the moment a part enters the first zone until it rolls out the last.
