Introduction
Picture this: You’re on the factory floor, and your PET blowing line is humming along. You need heat, and you need it fast. No waiting around. That’s exactly what we built these overheat protection heaters for. They’re compact powerhouses—halogen infrared tubes, packing 2500W at 400V, and they plug in with a standard R7s base. They’re the kind of workhorse you can trust in tight spots and brutal cycles, where the heat has to be quick, consistent, and absolutely reliable.
The Heat, Without the Wait
Here’s the thing: when you’re running a PET blowing head, time is money. Every second of warm-up delay is a second lost. That’s why we spec these at 400V and 2500W. It’s all about packing serious heat into a small space, so you can focus the energy right where you need it. The 300mm tube keeps the heat tight, so you’re not wasting energy warming up the whole machine frame. It’s fast. Really fast. But with that kind of power, you’ll want to make sure your machine’s cooling is set up to match.
What’s Inside Matters
We wrapped the heating element in a quartz tube, filled it with halogen, and added a reflective coating. The result? All that infrared energy gets pointed straight at the target. No fuss, no waste. The R7s connector is simple and solid. Two contacts, easy to install, and it stays put even when things get shaky. And the real peace-of-mind feature? The built-in overheat protection. If the temperature inside climbs too high, it cuts the power automatically. That means you’re protecting the filament and the rest of your controls from frying.
Built for the Real Work
In PET blowing, the heat has to be predictable. If it’s not, your cycle times slip and your scrap pile grows. These heaters slide right in as a direct replacement for standard R7s lamps, and they deliver that focused infrared heat you need, when you need it. That overheat protection? It’s the kind of feature that quietly saves you from a midnight breakdown call. And the coated tube helps keep the output steady, shift after shift. Just keep in mind, with this much power, you’ll want to make sure you’ve got enough airflow and clearance where you mount it. That way, you avoid hot spots and keep everything running smooth.
