Technical Deep-Dive: Power and Dimensions

Here’s the thing about these infrared halogen heat tubes. They were built for those industrial machines where space is at a premium, but you still need serious heat. We’re talking about a unit that runs at 400V and 2500W. That’s a lot of power packed into a 300mm length. What does that mean for you? It means you can focus that intense heat exactly where you need it—right on a mold face, a bearing, or a process line—without having to tear apart your whole machine setup. And the high voltage design? It keeps the current draw low for all that wattage. So your cables and contactors stay a sensible size. No headaches.

Material and Design: Halogen, Coating, and Connectors

Inside, it’s a quartz tube filled with halogen. The magic of the halogen is that it keeps the filament stable. It recycles the evaporated tungsten, sending it back to the filament. This stops the tube from blackening over time, so the lamp lasts way longer than a standard infrared one. We also added a reflective coating. It directs more of the IR energy forward, so you get more usable heat and less wasted. For the connections, we went with R7s bases. They can handle the high temperatures at the ends, make a solid contact, and are a simple, drop-in replacement for what you’re already using.

Application and Benefits: Fast Response, Tight Control

These tubes shine when you need heat that turns on and off fast, with repeatable control. They heat up almost instantly. That means you can shave time off your cycles, whether you’re doing PET blowing, thermoforming, or plastic welding. Because the output is so concentrated, you can use a smaller heater footprint. That makes everything easier to integrate and simpler to maintain. But wait—there is a trade-off. That kind of power density means you need proper cooling and the right thermal clearances. Make sure you’ve got the heat sinking and airflow sorted. If you don’t, you’ll shorten the life of the lamp.
