Introduction
Let’s get real. Glass annealing lines are energy monsters. And the heating stage? That’s where most of the electricity gets devoured. So we built the SK15 ceramic lamp holder to go straight after that cost. This isn’t just another heater. It’s a focused infrared emitter, built for the exact temperature curve annealing needs. It zeroes in on the lehr’s energy use and gives you a real, measurable cut in your yearly operating costs—without messing up your process control.
Technical Deep-Dive
The heart of the SK15 is a high-power infrared tube, running at 400V to pack the punch you need. That voltage keeps the energy output intense while keeping the current steady across the line. The size? It’s typically around 300mm, chosen to match the standard zones in annealing lehrs. That means even heat across the glass. This setup delivers the heat flux to warm the glass fast, which shortens the whole annealing cycle and lowers the kWh you burn per shift.
Material & Design
The SK15 ceramic lamp holder anchors a tough quartz infrared tube. The ceramic base stays solid under sustained high heat—no cracking. And the built-in SK15 connector gives you a secure, low-resistance electrical fit. This thing is designed as a straight swap for many existing industrial lamp holders, so the retrofit is simple. The quartz envelope handles thermal shock well and transmits infrared efficiently. That means the system can cycle on and off often without falling apart, which is exactly what you need in a high-duty-cycle annealing environment.
Application & Benefits
In annealing, you need heating that’s controlled and even, so internal stresses ease out. The SK15 infrared heater delivers focused radiant heat that sinks into the glass quickly, so the lehr doesn’t have to run at full power as long. That cuts energy use and helps with those peak demand charges. Out in the real world, installation is straightforward—wire it, set the zones, and keep an eye on it. But here’s the trade-off: that 400V, 2500W tube is seriously powerful, so your machine’s cooling and electrical setup need to be up to the task. If your lehr can handle the heat load, the SK15 gives you a no-nonsense route to lower electricity bills and annealing results you can count on.
