Heating Your Class 100 Cleanroom Without the Mess
If you’re running a Class 100 cleanroom, you already know that air filters only get you halfway there. The real headache? The stuff you can’t see. Outgassing and chemical byproducts can ruin a batch in seconds. Most standard heating elements just aren’t cut out for this. That’s why we stick with high-purity synthetic quartz infrared lamps. The big win here is that they don’t produce ozone. The deal with ozone Here is the thing: most short-wave IR lamps put out radiation in that 185nm to 254nm range. When that hits the oxygen in your air, you get ozone. In a cleanroom, that’s a nightmare. It oxidizes your sensitive parts and eats away at organic materials. We fixed this by shifting the spectral output of our quartz tubes. We basically blocked out the vacuum ultraviolet (VUV) range. You still get all the heat you need, but none of the chemical baggage. Why the materials matter We use high-purity fused silica for the outer shell. Why? Because it doesn’t “shed” particles when it heats up and cools down. We also scrub out the metallic impurities. If you leave those in, you get hot spots, and your tubes burn out way too fast. It’s about making something that actually lasts. You can pick the wattage and length that fits your space. Just a heads-up: if you cram a lot of wattage into a short tube, your mounting brackets are going to feel it. Make sure your housing can handle the heat without warping. Getting it up and running These are designed to be simple drop-in replacements for your current IR setup. We offer a few different termination options so you aren’t fighting with the wiring. And since there’s no ozone to deal with, your exhaust and scrubbing systems don’t have to work nearly as hard. One last tip: double-check your power supply voltage against the lamp specs. You don’t want to fry the filament the moment you flip the switch.
