Stop Burning Money on Your Glass Annealing
Let’s be honest: glass annealing is a total energy hog. If you’re still relying on those clunky old heating arrays, you’re probably watching a huge chunk of your power budget just vanish. Between the endless heat soak and those agonizingly slow ramp-up times, it’s a waste. We’ve found a better way. We pair SK15 ceramic lamp holders with short-wave infrared lamps to actually bring those costs down. Why the ceramic holders matter Here’s the thing about metal housings: they just can’t handle the heat. In an annealing lehr, the thermal cycling is brutal. Metal warps. It gives up. Ceramic is different. It stays put. It handles the high-wattage push needed to get glass hot—fast—without melting the connection points. Plus, the SK15 has a spring-loaded contact. This means the lamp stays snug even when the machine is vibrating. No more annoying arc-over issues that fry your cheaper holders every few months. Getting the heat where it actually belongs Short-wave IR is a different beast. Instead of wasting energy heating up all the air in the room, it shoots energy straight into the glass. When you go with a high-density wattage setup, the response is almost instant. You can finally cut down your soak times. But a quick heads-up: more wattage means the lamp tubes get scorching hot. You’ve got to get your reflectors right. If they’re pitted or oxidized, you’re basically heating your ceiling instead of your product. You could be losing 20% of your heat just because of a dirty mirror. Making the switch If you have the room in your footprint, swapping out old resistive heaters for an SK15 IR system is usually a pretty straightforward swap. You’ll see the difference in your kWh per unit almost immediately. Just do yourself a favor and check your wiring first. Make sure it’s rated for the peak current of the IR lamps. If the wiring is too thin, it’ll overheat—and that completely wipes out the energy savings you were chasing in the first place.
