Finding the Right Infrared Tubes for Your Bread Oven
Let’s be honest: OEM replacement tubes for imported bread ovens are getting ridiculously expensive. It makes sense that you’d want to find a drop-in replacement that doesn’t break the bank. But here’s the thing—if you just grab the first “similar” tube you find, you’re asking for trouble. You’ll likely end up with burnt-out filaments or bread that’s hot on the outside and cold in the middle. To get it right, you have to nail the spectral output and the electrical load. No shortcuts here. The Electrical Side of Things Reheating bread is a bit of a balancing act. You need a mix of short-wave and medium-wave infrared radiation. Why? Because you want the heat to soak deep into the crust without scorching the surface into a crisp. We build our tubes to match your original wattage and voltage exactly. It’s critical. If you plug a low-voltage tube into a high-voltage power supply, that filament is going to snap the second you flip the switch. On the flip side, under-powering a tube just means your bread takes forever to heat up. Nobody has time for that during a rush. Materials and the “Small Stuff” Most of our high-performance tubes use quartz glass infused with halogen. It’s a smart setup because it lets the filament run hotter, which actually makes the tube last longer. Now, let’s talk about connectors. We usually stick with R7s or SK15. They’re the standard, but please, double-check your pin spacing. I can’t stress this enough. Even a single millimeter of difference means the tube won’t sit right in the socket. That leads to arcing, and before you know it, your housing is fried. You might also see tubes with gold or ceramic coatings. These aren’t just for looks; they push the heat toward the bread instead of wasting it on the oven walls. A Word of Caution on “Budget” Options It’s tempting to go for a high-wattage budget alternative to get more heat, but be careful. Your oven’s wiring and relays have limits. If you try to shove a 2500W tube through a circuit meant for 1500W, you’re going to trip breakers or, worse, melt your insulation. It’s a mess you don’t want to clean up. Before you wire anything in, just take a quick look at the amp rating on your contactors. It takes two minutes and saves you a massive headache later.
