Thick glass cutting preheater

We built this preheater for one very specific, very frustrating problem: how to prep thick glass for cutting without smudging the beautiful printed pattern underneath. Here’s the solution we landed on: shortwave infrared halogen lamps. They give you the exact heat profile you need to get the glass ready for tempering and cutting, but they never touch the silk-screened design. It stays pristine.

Power, Voltage, and Size

At the heart of this thing is a high-output halogen lamp, built to run all day, every day. It’s a 2500W lamp on a 400V line. That’s not by accident. That specific power-to-voltage mix gives you the muscle to heat thick glass fast. But it also means you need to make sure your power supply and the machine’s cooling are up to the task. The tube itself is 300mm long, which creates a tight, focused heat zone. It’s a compact footprint that fits right into your existing line without needing a total overhaul.
