carbon fiber quartz tubular heat lamp in RU TH

May 6, 2026

Introduction

We built this carbon fiber quartz tubular heat lamp for one reason: industrial heating. It comes in RU and TH setups, and it’s all about getting serious heat into tight spots. Think of it as a compact powerhouse. It’s designed for spot heating, process heating, and slipping right into machines where space is at a premium—and where you need dependable, repeatable output.

What’s Under the Hood

This lamp runs on short-wave infrared, which means two things: it responds instantly, and it packs a ton of heat into a small space. Typical specs? 400V and 2500W. That’s a lot of muscle in a tidy package. The tube is just 300mm long, so you can zero in on your target without turning the whole machine bay into a sauna. That high voltage and wattage push the filament temperature way up, which cranks the radiant output. So it hits operating temperature in seconds—way faster than your standard resistance heaters. But here’s the trade-off: your fixture and wiring need to be rated for 400V, and whatever’s nearby needs proper cooling. Otherwise, ambient heat builds up fast.

Materials and Design, Plain and Simple

The heart of it is a quartz envelope. Why quartz? Because it can handle extreme heat and stays optically clear, even when things get white-hot. Inside, a carbon filament gives you mechanical toughness and stable resistance, even when the lamp cycles through rapid temperature swings. And the halogen cycle does a neat trick: it redeposits material that evaporates off the filament, keeping the filament clean. The payoff? Consistent output over the lamp’s life. We topped it off with an R7s connector. That end-cap design gives you a simple two-point mount that lines up cleanly in standard reflectors and fixtures. In other words, it’s a drop-in replacement for many existing systems.

Where It Shines (And Why It Works)

Out on the shop floor, this lamp earns its keep. You’ll see it used for drying, curing, thermoforming, and pre-heating. In PET blowing lines, the concentrated heat helps you keep parison temperature under control without scorching the mold area. In packaging and converting, it dries coatings quickly without dumping extra heat everywhere. The tubular shape and short-wave output let you focus energy exactly where you need it, which makes your process more repeatable. The R7s interface keeps installation fast. The quartz build shrugs off thermal shock. Just plan for proper thermal management and voltage-rated components, and you’ve got a heating module that can take a beating—and keep on performing.
