SIG Blomax 10: The Right Bulb for Your KHS Heater
We built the SIG Blomax 10 infrared bulb to be a straight-up, drop-in replacement for KHS blow molding machines. Its whole job is simple: keep the PET preform area evenly hot, so your line runs the way it should—steady, without hot spots.
Power, Voltage, and Size: What It Brings
This bulb runs at 2500W and 400V. That combo isn’t random. It’s exactly what you need to pack a lot of heat into a small space, so the PET heats up fast when the cycle demands it. And the length? 300mm. That’s the standard size that fits right into the existing lamp housing on KHS machines—no modifications, no messing around. The shape is matched to the preform path, so the heat lands where it matters.
The Build: Quartz, Coating, and a Solid Connection
Inside, you’ve got a high-purity quartz envelope. It’s there because it can take the heat swings and the high temps that blow molding throws at it, without cracking under the pressure. Then there’s the infrared coating. It helps focus the energy where it’s needed—right onto the PET—so you get better absorption and less wasted heat. And the R7s connector? It’s a double-ended linear design that gives you a solid, two-point electrical contact. That means reliable current handling and a true plug-and-play replacement.
Why It Matters: Even Heat, Fewer Headaches
On a KHS line, uneven heating is a fast track to rejects and slowdowns. The Blomax 10 was designed to smooth that out, giving you a more uniform thermal field across the preform. Installation is quick. No rewiring. No custom brackets. Just swap it in and get back to work. One thing to keep in mind: with 2500W, it puts out a lot of heat. Make sure your machine’s cooling system is in good shape, so you don’t end up overheating nearby parts. Before you swap it in, double-check the voltage and connector match. That keeps everything safe and right from the first heat cycle.
