618mm 400v 2000w Infrared Quartz Halogen Heating Tube

May 25, 2026

Introduction

We built the 618mm 400V 2000W Infrared Quartz Halogen Heating Tube to be the kind of part you can drop in and forget about—because it just works. It’s for industrial heating setups where you need heat fast, and you need it to be intense. No fuss. No waiting around.

What makes it tick

Here’s the thing: packing 2000W into a 618mm tube gives you a seriously focused heat footprint. You get high watt density without having to blow up the footprint of your machine bay. And the 400V rating? That’s a quiet win. It pulls less current than a 230V version, so line losses drop and you can use thinner gauge wiring over longer runs. It also means your contactors and terminals stay cooler, which is one of those details that quietly makes life easier.

Built to last, designed to fit

The quartz envelope handles rapid heat-up and cool-down cycles without blinking. Inside, the halogen fill keeps the filament stable, so the output stays consistent over the life of the tube. The infrared coating is the other neat touch. It tunes the spectrum so more energy goes straight to the work surface, not into warming the air around it. Then there’s the practical part: we went with an R7s base. Swap the tube, and it drops right in. No rewiring. No headaches.

Where it shines

This tube is at home in plastic heating, thermoforming, drying, and curing—anywhere speed matters. It hits operating temperature quickly, which can shorten cycle times and keep things moving. Just one note: that high heat density means you’ll want solid machine cooling and a well-designed reflector. They keep ambient temps in check and protect nearby components.
