SIPA SFL 6/6: The Reliable Workhorse for PET Blow-Molding Heat
We built the SIPA SFL 6/6 linear blower IR lamp for one reason: to give you the performance of an OEM-grade part without the headache. It’s not just another heater. It’s a purpose-built tool, designed specifically for PET blow-molding lines. The goal is simple: deliver steady, high-density heat you can count on, without the burnout that seems to plague other options.
Power, Voltage, and Size—Tailored for the Job
Let’s get into the details. The SFL 6/6 runs at 2500W and 400V. That combination is all about packing in the heat, not just drawing more current. It’s a smart choice that keeps line losses down and eases the strain on your machine’s electrical system. And the size? It’s a standard 300mm length. That means it drops right into your existing blow-molding cavities without any fuss—no modifications, no rework. Just swap it in and get back to work.
Built to Last: Halogen, Coating, and a Solid Connection
Inside, you’ve got a halogen-filled quartz tube. That design means it heats up fast and stays steady, even after countless on-off cycles. No more worrying about the output dipping over time. The tube’s internal coating reflects infrared energy back onto the PET preform. That means more of the heat goes where it’s needed, and less is wasted. Efficiency you can feel. And the connector? We went with an R7s. It’s a tough, direct fit that handles high heat at the terminals and stays tight in a vibrating environment. Because a loose connection doesn’t just mean a bad lamp—it means downtime.
What It Feels Like on the Line
On a PET blow-molding line, the SFL 6/6 brings the kind of heat you need for precise preform stretching: fast and uniform. The linear blower setup keeps the heat even across the whole preform, so you don’t get weak spots. Now, with 2500W packed into a 300mm tube, your machine’s cooling system needs to be up to the task. That heat has to go somewhere. But when everything is balanced, you get dependable heating cycles, fewer lamp replacements, and consistent output—bottle after bottle.
