How to handle infrared heat without blowing things up
If you’re running chemical cleaning lines with volatile solvents, a standard infrared lamp isn’t just a tool—it’s a risk. One tiny spark or a leaky seal and you’ve got a disaster on your hands. We handle this by tucking the heating element away inside a custom stainless steel housing. Simple, but it works. The build We stick to 304 or 316L stainless steel. Why? Because cleaning agents are nasty, and these grades won’t pit or corrode when things get messy. Think of the housing as a shield. It keeps the energized lamp completely separate from the flammable air around it. We also use certified explosion-proof glands for the cable entries. That way, hazardous vapors can’t sneak into the electrical connections. Keeping it safe The lamp lives inside a steel tube, sealed off with high-temp quartz or borosilicate glass. We don’t just slap some welds on the ends and call it a day. We use precision-machined flanges to make sure the whole thing is gas-tight. You still get that direct radiative heat you need, but any electrical arcs stay trapped inside the steel. Depending on how rough your shop floor is—and how much internal pressure we’re dealing with—we’ll beef up the wall thickness of the steel. The honest trade-offs Now, this isn’t magic. There’s a catch. Adding all that steel adds thermal mass. You won’t get that “instant-on” snap you get with a bare lamp because the housing has to soak up some energy first. You’ll need to tweak your PID controllers to handle that little bit of lag during warm-up. Also, watch your wiring. If you use the wrong gauge cable over a long run, the voltage drop will kill your wattage. Just make sure your power supply can actually handle the peak load of the array. It’s a solid, drop-in replacement for those old open-lamp systems that the safety inspectors are now flagging.
