Introduction
We built this 623mm, 400V, 2000W halogen heater for one reason: to be a straight-up, drop-in replacement for the tough industrial jobs. It’s for those machines that need serious heat packed into a small space. You get the power you need without having to tear apart and redesign the whole heating setup.
The Inside Story
The 2000W at 400V isn’t an accident. It’s a deliberate choice. That power density packed into the 623mm length means you get a rapid temperature rise and can keep a tight grip on your process. And running at 400V? It lowers the current draw compared to lower voltage units. That means you can use smaller wiring and put less stress on your contacts. The payoff is a more reliable connection and less heat building up at the terminals.
What It’s Made Of
The heart of it is a quartz envelope holding the halogen filament. That chemistry keeps the filament clean, even at scorching temperatures. The result is a longer lamp life and steady, consistent output over time. The R7s base is the standard, solid connector for this size. It makes wiring and swapping out the unit simple. And the compact footprint means it can squeeze into tight spots where other heaters just can’t go.
Where It Shines
This configuration is the go-to for applications like PET blowing, plastic welding, and shrink tunnels—anywhere you need precise, focused heat. It’s a simple swap for aging units, so you can get your line back on its feet fast. Now, with that much heat density comes a trade-off: thermal load. You have to make sure your machine’s cooling system is up to the task. If it can’t handle the ambient heat, you risk overheating the components nearby.
