2.5um quartz carbon infrared heating lamp

May 27, 2026

Introduction

Picture this: you’ve got a job that needs heat, and it needs it now. Fast, focused, and right on target. That’s exactly why we built our 2.5um quartz carbon infrared heating lamp. It’s for those moments on the factory floor when you’re pushing through high-speed drying, curing, or thermoforming—and there’s no room for guesswork with the temperature.

The Power Behind the Heat

Here’s the thing: this lamp is a powerhouse in a small package. We packed up to 2500W of heat into just a 300mm length. That means you can blast heat exactly where you need it, without tearing apart your whole setup. And the 400V configuration? It’s all about keeping things simple. It keeps the current manageable, so you can use thinner wiring and not worry about voltage dropping off over distance. The result? A steady, even heat profile across the whole surface you’re working on.

What Makes It Tick

Inside, you’ve got a carbon filament tucked inside a quartz envelope. This combo is the secret to how quickly it heats up and how well it handles sudden temperature shifts. The 2.5um output lives in the shortwave band, which punches right through materials. You’re not just warming the surface—you’re heating all the way through. And the R7s double-ended connector? It makes installation a breeze. Just drop it in, and you’ve got a solid, reliable connection. It stays stable even when the shop floor is shaking, rattling, and cycling through hot and cold.

Where It Shines (And What to Watch For)

This lamp shines when you need heat that’s fast and repeatable. Think PET blowing, coating curing, or plastic welding. The shortwave output hits its peak in seconds, so you can cut down on cycle time and speed up your whole line. But, there’s a trade-off. That intense heat density means you need to keep things cool and make sure your reflectors are lined up just right. Otherwise, you risk overheating nearby parts. If you size the lamp to match your thermal needs, you’ll get a heating element you can count on. It’s reliable, easy to service, and built to keep its performance steady, shift after shift.
