Getting Heat Right When Your Furnace is Too Small

Let’s be honest: standard infrared lamps are great until you’re working with a non-standard glass bending furnace. Then, they’re a headache. If your furnace interior is cramped, you can’t just force a stock lamp into a space where it doesn’t fit. It doesn’t work, and it’s frustrating. That’s why we just build them to fit your specific setup. Custom lengths, custom shapes—whatever the job needs.

Engineering Ultra-Wide Infrared Heating Units for Low-E Glass Preheating

Preheating wide-format Low-E glass requires a uniform heat flux across the entire substrate. When you are dealing with widths exceeding 3 meters, standard off-the-shelf lamps create cold spots. We solve this by customizing continuous infrared heating units tailored to the specific footprint of your baking tunnel.

Managing Power Density in Ultra-Long Tubes

Designing a lamp longer than 3 meters isn’t as simple as stretching the quartz. Long tubes face significant voltage drop issues. To maintain a consistent temperature across the wide-format glass, we spec out the wattage and voltage to ensure the center of the tube doesn’t lag behind the ends. You need high-density output to get the glass up to temperature quickly before it hits the coating chamber.
