Why Ruby Lamps are the Secret to Better Steam Ovens
Let’s be honest: steam ovens are a nightmare for heating elements. You’ve got thick humidity fighting against intense heat, which is basically a recipe for disaster. Usually, this means your filaments oxidize way too fast or your seals just give up. That’s why we use ruby-coated quartz bulbs. They actually hold up. The magic of the ruby coating Here is the thing about standard quartz tubes—they let too much energy leak out as long-wave radiation. It’s wasteful. By adding that ruby-red coating, we change how the heat behaves. The coating bounces some of that heat back into the tube. In a pizza oven, this is huge. Instead of wasting energy heating up the steam in the air, the heat hits the dough immediately. You don’t get that annoying temperature drop when the steam kicks in, which means your crust actually stays crisp. Building something that lasts Inside these bulbs, we use a halogen cycle. It basically pushes the tungsten back onto the wire so the filament doesn’t just burn out and die. We also use a high-grade quartz. Why? Because steam cycles cause the glass to expand and shrink rapidly. If you use cheap glass, it’ll crack under that kind of stress. Our stuff doesn’t. One quick tip: keep an eye on your wiring. These bulbs pull a lot of current. If your controllers aren’t dialed in for the specific wattage, you’re going to deal with flickering or burnt-out contact points. It’s a pain to fix, so just get the voltage right from the start. Making them work for you The good news is that these are easy to swap into most industrial pizza oven arrays. You get a ton of heat in a very small space. But there is a catch. Because of that ruby coating, the pressure inside the tube is higher than usual. This means you can’t just crank the voltage past the rated spec to get “extra” heat. If you overdrive them, you’ll blow the seal. Keep your voltage steady, and these lamps will last you a long time.
