Heavy-Duty Halogen Heater: 400V 2500W R7s Tube for Industrial Heat
We built this heavy-duty heater for one reason: to throw serious, controllable infrared heat where standard heaters just can’t reach. It’s a quartz halogen tube, made for industrial machines and the rough conditions of the plant floor.
The Power Behind It
Here’s the thing—it runs on 400V and pulls 2500W. That means you get a ton of heat without draining your electrical system. And it’s compact. Just 300mm long. So it slips into tight spots and cramped machine frames without a fight. It heats up fast. Really fast. And that responsiveness? It changes how you approach the job. But with that power comes a little reality check. Your enclosure needs to breathe. Make sure you’ve got enough airflow or heat sinking ready. Otherwise, the components will run hot.
Built to Last
The quartz envelope is halogen-filled, which keeps the filament temperature steady and helps the tube stay clear over time—no frustrating blackening. We added a durable reflective coating, too. It pushes more energy forward, so you’re heating the work zone, not wasting output all over the place. The R7s base is simple and rugged. It locks in tight and handles vibration way better than those fragile caps. Installation is just slide it in and secure it. No adapters. No head-scratching.
Where It Shines
Use this tube when you need intense spot heating, when you’re preheating tooling, or when you just need to hold a steady process temperature. It takes thermal cycling in stride—the kind that comes from constant starts and stops. And it stands up to shock and vibration better than a lot of ceramic or wire-wound options. You get consistent output and a long service life. Just make sure the equipment around it can handle the heat load.
