Getting Ultra-Long Infrared Heating Right for Glass Tunnel Kilns

If you’re trying to heat a glass tunnel kiln over a stretch of 2 meters or more, you quickly realize you can’t just take a standard lamp and stretch it out. It doesn’t work like that. You run into two big headaches almost immediately: voltage drop and thermal expansion.

The struggle with long tubes

Here’s the thing about power. In a setup this long, a basic 220V line usually can’t keep the heat steady. You end up with cold spots, which is a nightmare when you’re looking for consistency. We handle this by dialing in the wattage and voltage specifically for the length. The goal is a filament that stays hot from the first inch to the last. You get this intense, deep heat that hits the glass immediately. It’s powerful. And because it works so fast, you can stop worrying about those massive, space-wasting pre-heating zones.
