Stop Fighting Your Multi-Deck Oven
If you’ve spent any time with a multi-deck oven, you know the headache. Heat rises. Simple physics. But in a professional kitchen, that means your top deck is scorching everything while the bottom deck is barely keeping up. It’s frustrating, it makes your browning inconsistent, and it’s a nightmare when the health inspector comes around for a safety audit. We found a better way to handle this. Instead of relying on one big blast of hot air, we use independent infrared (IR) heating tubes for every single layer.
How it actually works
Most ovens just heat up a big cavity of air and hope for the best. We do things differently. IR tubes use radiative heat. Think of it like the sun—the heat doesn’t need to warm up the air first; it hits the food directly. The best part? Each deck gets its own PID controller and SSR. This means you can tweak the wattage for the bottom deck without touching the top. If your oven base is leaking heat, you don’t have to crank the whole machine. You just bump up the power on those specific bottom tubes. Simple.
The nitty-gritty on the gear
We use high-purity quartz glass for the envelopes. Why? Because it doesn’t crack when the temperature swings wildly. Inside, we use halogen-doped tungsten filaments to get a lot more power out of a small space. Just a heads-up on the electrical side: make sure your voltage and wattage match your power rail. High-wattage tubes get you up to temp fast, but they’re harder on your wiring. Check your connectors. You don’t want a terminal burning out in the middle of a dinner rush.
What to expect in the kitchen
The biggest win here is the recovery time. When you swing that oven door open, you lose a ton of heat. With IR tubes, you aren’t waiting for a massive volume of air to warm back up. It’s fast. Really fast. One thing to watch out for: IR is directional. If you’re baking something tall, the top might char before the middle is actually cooked through. To fix that, just balance the IR intensity with a steady ambient temperature. That keeps your food safe and your crusts perfect.
