Stop Wasting Money Heating the Air in Your Wine Glass Line

Let’s be honest: those energy bills during the annealing phase can be a nightmare. Most shops are basically paying to heat up the entire oven air just to get the glass to behave. It’s a waste. We do things differently. We use shortwave IR lamps that point the heat directly at the glass. No more heating the atmosphere. You’re putting the energy exactly where the thermal stress is, which means your power bill actually starts to look reasonable. Getting the heat right The trick with a wine glass is hitting that annealing point without melting the stem. You need heat that’s dense and fast. Our IR tubes don’t take forever to warm up like those old resistive elements. They hit the target temperature in seconds. That means you can speed up your conveyor and get more glass through the door. Just a heads-up: if you go for higher wattage in a shorter tube, make sure your ventilation is up to the task. If the housing can’t breathe, you’re going to melt your sockets. And nobody wants to deal with that on a Tuesday morning. The gear We use high-purity quartz for the lamps. Why? Because it lets the IR spectrum actually get through the glass wall instead of bouncing off. Whether you’re running R7s or Sk15 connectors, these are basically drop-in replacements for most industrial lehrs. It’s a simple swap. One pro tip: put gold-coated reflectors behind the tubes. It bounces the heat back into the glassware so it doesn’t just leak into the machine frame. It’s a small detail that saves a lot of energy. The balancing act Now, shortwave IR is powerful. Maybe too powerful if you aren’t careful. If the lamps are too close, you’ll get hot spots. That leads to optical distortions—those weird warps in the glass that make a piece look cheap. You have to find the sweet spot between your lamp wattage and your belt speed. We usually suggest a staged approach. Start low, peak in the center of the lehr, and then taper off. It keeps the glass stable, prevents cracking, and drops your kWh per unit. It just works.
