Why we use quartz tubes for precision heating

Most heating elements are just too slow. They’re heavy, they hold onto heat for way too long, and they make it a nightmare to hit those tight temperature windows when you’re running a complex bake. That’s why we use high-purity quartz tubes inside our stainless steel convection ovens. Quartz doesn’t have that annoying “thermal lag.” It heats up and cools down almost the second you tell it to. Getting that instant response If you want step-style temperature control, you need a heat source that reacts in seconds. Not minutes. With quartz, we can flip the power on and off rapidly. The moment the controller cuts the juice, the heat drops. This kills the “overshoot” problem you get with those chunky metal coils. You can jump from a high-heat sear to a low-temp hold without sitting around waiting for the oven to bleed off extra energy. It just works. The setup We wrap these tubes in a 304 or 316 stainless steel chassis. The steel does the heavy lifting—it holds everything together and bounces infrared radiation right back toward your product. Since the quartz is transparent, the short-wave radiation goes straight into the food. Meanwhile, the convection fans keep the air moving so you don’t end up with a burnt surface and a raw center. The honest trade-offs Look, nothing is perfect. This kind of speed comes with a catch: quartz is brittle. If the oven vibrates too much, or if someone is a bit too rough during cleaning, those tubes will crack. You also have to be smart about the mounting brackets. You can’t just clamp them tight against the steel frame, or they’ll snap the moment they expand under high heat. They need a little room to breathe. One last tip on the wiring: don’t use a mechanical contactor. This system pulses constantly, and a mechanical switch will just burn itself out. Go with a solid-state relay (SSR) instead. It can handle the high-frequency switching without breaking a sweat.

Stop Drying Out Your Food: Why We Added IR Heaters to Our Convection Ovens

Ever notice how standard convection ovens can leave your food feeling like cardboard? It happens because those forced-air fans are a bit too aggressive—they strip away moisture faster than the food can actually cook. To fix this, we started putting stainless steel infrared (IR) heaters inside the ovens. Instead of just blowing hot air around, IR uses electromagnetic waves. Think of it like the sun hitting your skin on a summer day; the heat goes straight in, rather than just swirling around the surface. Here is how the magic actually works. We use short-wave or medium-wave emitters tucked into stainless steel casings. The cool part? You aren’t just relying on the air temperature anymore. These IR waves get the water molecules inside the food vibrating, which spikes the internal temperature quickly. You get that perfect, seared crust that locks all the juices inside before the fans have a chance to dry everything out. Why the stainless steel? Two reasons. First, ovens are humid, and we don’t want anything rusting. Second, it’s all about where the heat goes. The steel housing reflects the energy forward, aiming it right at your food instead of letting it waste away on the oven walls. And a quick tip: pay attention to your power density. If you use a high-wattage IR array, your cook times drop. Less time in the oven means less time for your moisture to evaporate. Simple as that. The tricky part (and how to handle it) Now, IR heating is fast. Like, really fast. If you just wire these up and flip a switch, you’re going to scorch your food. You need a PID controller or a precision timer to keep things under control. It’s all a balancing act between the IR intensity and the fan speed. If your fan is cranking too hard, it’ll blow away that thin layer of moisture before the IR can sear the surface. We’ve found that zoning the heaters is the way to go. By putting IR elements at both the top and bottom, you can tweak the heat flow independently. It stops that “dry-out” effect you see in those cheap, budget ovens and actually gives you control over the result.
