Introduction
We built this heater block with one machine in mind: your Sidel. It’s a straight-up, drop-in replacement for the factory unit. Same high-purity quartz. Same tungsten filaments. But here’s the part you’ll really like—you get that exact thermal performance without paying for the “name brand” price tag.
Power and Physical Specs, Straight Talk
This heater was designed to match your Sidel’s electrical setup, plain and simple. It runs on a standard 400V input and pulls just the right wattage to hit those temperature targets, every single time. Of course, the fit has to be perfect. The dimensions are spot-on, so it slips right into the existing brackets and clears all the tight spots. That means installation isn’t a wrestling match. Take the 300mm length, for example. It spreads the heat just the way you need, covering the preform neck and body evenly.
The Materials That Make It Work
Inside, you’ve got a quartz tube holding a tungsten filament. It’s a classic combo, trusted for one reason—it heats up fast and stays stable. We also fill the tube with halogen gas. That little detail does a lot. It creates a cycle that puts evaporated tungsten back onto the filament. The payoff? Consistent brightness and a longer life. The R7s connector is the standard for this kind of high-intensity lamp. It handles the current and gives you a solid, low-resistance connection. And the internal wiring? It’s rated to handle the serious heat inside the machine.
Real-World Use on the Production Floor
This heater was born for the PET blowing process. It needs to deliver intense heat, fast, to soften the preform. And that’s exactly what the halogen design does. It heats up in seconds, which means less waiting around. The quartz envelope can take the thermal shock, and it stays clear enough to keep an eye on the temperature. Just keep one thing in mind: this is a 2500W unit, so it puts out serious localized heat. Your machine’s cooling system needs to be ready for that extra load. But when everything is set up right, you get reliable performance, an easy swap-out, and lower running costs.
