Introduction
Ever feel like you’re constantly fighting a losing battle with your older PET blow molding machines? That sinking feeling when you know the equipment is aging, but a full overhaul just isn’t in the budget? Here’s the thing: the Sidel Universal 2 heater lamp was built for exactly that moment. It’s a direct-fit infrared heating element, plain and simple. The idea is to give your older machines new life—without tearing them down and starting over. Just swap out the old heating unit, and you’re back to running with the kind of consistent, high-output performance you need on the shop floor.
What’s Under the Hood
Let’s get into the details, but don’t worry—no engineering degree required. The lamp runs on a 400V electrical input and packs a 2500W punch. That power combo is what gives you the intense heat you need to get those PET preforms up to the perfect stretch temperature, fast. And it’s a perfect fit—literally. The 300mm length lines up exactly with the Universal 2 heating zone, so it drops right into the existing mounts. This isn’t just random specs thrown together. It’s about matching the machine’s thermal needs so the heating stays rock-solid, cycle after cycle.
The Design That Just Works
The magic is in the build. The lamp uses a quartz tube with a shortwave infrared coating. This focuses all that energy right where you need it: on the preform surface. Less wasted heat. Lower energy use. Inside, the halogen heating element is the star of the show. It responds instantly. Temperature ramps up quickly, which means shorter warm-up times and keeps your cycles tight. And the best part? The R7s connector makes the install a breeze. It lines up with your original socket, so you just wire it in without messing with the machine’s electrical setup. Less downtime. Fewer headaches.
The Payoff on the Floor
Let’s be honest—heater lamps on PET blow molding machines get a serious beating. Constant heating, cooling, and mechanical vibration take their toll. It’s what leads to inconsistent heating and those frustrating, frequent burn-outs. This upgrade tackles those two headaches head-on. The coated quartz tube stands up to the thermal stress, keeping output steady for thousands of hours. And with the 400V, 2500W setup, you get the heat you need to push for higher throughput. But there is one thing to keep in mind. The increased power density does mean more ambient heat around the heating zone. So, you’ve got to make sure your machine’s cooling system is up to the task to keep everything from overheating. If your cooling and power infrastructure can handle the load, this upgrade is a straightforward way to get your older machine running faster. It’s about getting more life out of what you already have.
