Stop Letting Moisture Kill Your Infrared Heaters
If you’ve ever run infrared lamps in a place that’s humid or prone to splashes, you know the drill. One minute everything is working fine, and the next, the lamp pops. It usually happens because moisture hits that scorching hot quartz glass, causing a thermal shock, or water creeps into the terminals and shorts the whole thing out. It’s frustrating, and it’s expensive. We decided to fix this by wrapping our replacement heating elements in IP65-rated housing.
What “IP65” actually means for you
In plain English? It means the unit is dust-tight and can handle a low-pressure water jet without breaking a sweat. The real secret is in the connection points. Usually, where the wires meet the lamp is the weakest spot in the entire setup. If water gets in there, you get an immediate arc-over and a dead heater. We stopped that by using industrial gaskets and sealed cable glands to keep those electrical contacts bone-dry.
Dealing with fog and splashes
Then there’s the fog. You’ve seen it—that thin film of condensation that forms on the cooler parts of the heater. It doesn’t just look messy; it actually messes with how the heat radiates and can create dangerous hotspots on the glass. We tweaked the shape of the enclosure so that condensate can’t pool on the emitter. And while our quartz tubes are tough enough to handle the heat, the IP65 shell acts like a shield. It keeps random splashes from hitting the tube while it’s running, which saves the glass from cracking.
The honest trade-offs
Now, this isn’t a magic fix without a catch. First, the shell makes the heater bulkier. You can’t just squeeze these into a tight spot designed for a bare bulb. You’ll need a bit more breathing room. Also, you’re adding a layer of material between the element and whatever you’re heating. The infrared waves still get through, but the heat distribution might feel a little different than an open-air lamp. You’ll probably want to tweak your PID controllers to get the timing just right. Just make sure you wire it up with a properly rated contactor. And a quick heads-up: if you’re in an environment with constant, high-pressure wash-downs, you might want to skip this and go straight to IP67.
