Technical Deep-Dive: Power, Voltage, and Dimensions
Let’s get into the guts of this tower heater. At its heart, we’re running a 400V, 2500W halogen lamp, all tucked inside a 300mm quartz tube. This isn’t about warming up a whole room. It’s about creating a tight, focused blast of heat exactly where you need it. Sticking with 400V is a smart move. It means the current draw is lower than a 230V design, which cuts down on energy loss and lets us use thinner wiring inside. And that 300mm length? It’s just right. The heater fits neatly into standard machine channels—no awkward overhang. You get heat that’s consistent and predictable along the entire length, so you can nail your process settings without second-guessing yourself.
Material & Design: Coated Quartz and R7s Connectors
The quartz envelope is built to take the heat—and the shock of rapid on-off cycles. It won’t crack under pressure. We’ve added a hard-coat finish that shields the quartz from contamination and helps prevent hot spots that can kill a lamp early. The halogen fill gas keeps the filament stable, even at extreme temperatures, so the output stays steady over the life of the lamp. Then there are the R7s connectors. They’re the real workhorses. They create a secure, high-temp connection that’s a cinch to wire up right on the shop floor. Once they’re in, they stay put—no worrying about them working loose if things get a little shaky.
Application & Benefits: PET Blowing and High Heat Density
When you’re blowing PET, you need heat that’s fast and focused. You have to soften the preform neck and parison quickly, without turning the rest of the machine into a sauna. This tower heater brings that kind of heat density, which keeps your cycle times moving. And the best part? It’s a straight swap for what you’re already using. No need to redesign your tooling. Just one thing to keep in mind—with 2500W of power, you need to plan for serious cooling around the heating zone. Make sure you’ve got enough airflow and shielding to keep everything else running at a safe temperature.
