Introduction

Let’s talk about the glass tempering preheating lamp. We built this thing for one reason: to nail the instant tempering phase in glassware production. It’s a focused solution, plain and simple. It uses shortwave infrared halogen technology to get the job done. This means you get rapid, targeted heat right where you need it. The whole point is to handle the thermal shock that makes the preheating stage so tricky.

Here’s the heart of it. The lamp is a powerhouse, packing a 2500W punch on a 400V supply. That’s a serious industrial setup, designed to work with heavy-duty control systems, not your home wiring. This power-to-voltage ratio is what gives you the wattage density needed to heat glass surfaces fast. And fast is the name of the game. You get that intense heat without overloading the line. The size is no accident, either. We settled on a 300mm tube length. It’s a calculated compromise that gives you a focused heating zone that fits perfectly into standard machine housings. No wasted space. Just the right fit.
