Giving Your Old Convection Oven a Second Life with Twin Tube IR
Let’s be honest: old convection ovens can be a pain. You deal with cold spots, heat that takes forever to bounce back after you open the door, and that feeling that your equipment just can’t keep up with the workload. But before you spend a fortune on a brand-new machine, there’s a simpler way. Swapping out your old heating elements for custom Twin Tube Infrared (IR) heaters is basically like giving your oven a heart transplant. It brings the performance back without you having to toss the whole chassis. The secret is in the heat density. We build these twin tube setups to get as much surface area as possible out of the radiant filament. By doubling up the tubes, we’re packing more infrared energy into every inch. The result? You hit your target temps way faster. We can build these to match whatever voltage and wattage you’re already running. And if you’re tight on space but need a ton of heat, we can wind the filament differently to concentrate that energy. Just a heads-up: if you push for really high wattage in a short tube, your sockets are going to feel the heat, so keep an eye on that thermal load. Getting them to actually work for you We use high-purity quartz glass because it lets the IR light pass through without getting blocked. Depending on what you’re actually heating, we can add coatings to shift the spectrum to shortwave or medium-wave. It’s the difference between a surface sear and heat that actually sinks deep into your product. As for the install, it’s pretty painless. We usually stick with R7s or Sk15 bases. They’re standard for a reason—they just fit. You can usually wire them right in without having to rip apart your electrical housing. The trade-off Here’s the thing: this setup turns a sluggish oven into something that responds almost instantly. You get that punchy radiant heat working alongside your air circulation. For drying or curing, it’s a powerhouse. But there is a catch. IR tubes aren’t like those chunky old coil heaters. They’re fragile. If they take a hard hit or get pelted with debris, they’ll crack. You’ll want to make sure your guards are tight and secure so nothing bumps into them while you’re loading the oven. It’s a small price to pay for a machine that actually works the way you need it to.
