Introduction
We built this infrared heating lamp to be a straight-up, drop-in replacement for the SIPA SFR 16 rotary system. The idea was simple: make a lamp that not only meets the original specs but also works across most global blow-molding setups. This thing was made for the shop floor, not for sitting pretty in a showroom.
What’s Under the Hood: Power, Voltage, and Size
At its heart, this unit runs on a 400V, 2500W setup. That’s not by accident. The high voltage packs a serious punch into a compact 300mm quartz tube, giving you the intense heat you need to quickly warm up PET preforms. That 2500W rating means the lamp can handle the heat of non-stop production without the output dipping. But, and this is important, that kind of power density means your machine’s cooling system has to be up to the task. If the area around the lamp gets too hot, you’ll shorten its lifespan.
The Details: Halogen, Coating, and Connectors
We use a shortwave halogen element inside a high-purity quartz tube. The halogen cycle keeps the filament performance steady, which means consistent heating over the life of the lamp. The tube itself has a special coating to focus the infrared energy. That way, the heat goes right into the preform, where it’s needed, instead of being wasted on the machine frame. And the R7s connector? It’s the standard for a reason. It gives you a secure, high-amperage connection that’s easy to wire up and easy to maintain. No custom brackets. No complicated rewiring.
Why It Matters: Solving the Real Problem
This lamp was born for PET blow molding, where every second counts. Its fast-start capability and precise heat control mean your machine can keep up with those high cycle speeds without waiting around for the heating zone to catch up. We designed it to fit the SIPA SFR 16 footprint and electrical specs, making it a universal upgrade. And we keep these units in stock, so your maintenance team doesn’t have to wait weeks for a burn-out. You wire it in, and your machine gets right back to work. This is a direct, spec-for-spec replacement that cuts through the real-world headaches of downtime and supply chain delays. It was engineered to take a beating and just keep running.
