Getting Your PET Heating Right: SIPA SFR 16 and Krones Contiform Lamps

If you’re running a SIPA SFR 16 rotary or a Krones Contiform, you already know the deal. The heating oven is usually where things get tricky. It’s the bottleneck. You need those shortwave infrared lamps to soften the PET preforms just right. Too cold, and the bottle won’t blow. Too hot, and you’ve scorched the plastic. We make replacement lamps that hit that same OEM sweet spot, but without the eye-watering maintenance costs. Heat and Power (The Gritty Part) These lamps pull a lot of wattage. They have to. That’s the only way to get the heat transfer fast enough to keep your line moving. We build these tubes to handle the exact voltage your rotary oven demands. Why? Because if the wattage dips even a tiny bit, your heat profile goes sideways. Suddenly, you’re looking at uneven wall thickness in your bottles. Nobody wants that. You’ve also got to keep an eye on your power supply. A 400V system gives you the punch you need, but it’s hard on the contacts. To stop the tubes from bowing under all that thermal stress, we use high-grade quartz. It just holds up better. Fitting Them In We kept the design simple. Depending on your oven, we use standard R7s or Sk15 connectors. It’s a drop-in replacement. No messing around with rewiring or spending hours on a Saturday trying to make things fit. And here’s a little secret: the coating is where the real work happens. We use specific reflectors to push the heat inward toward the preform. It stops the heat from bleeding into the oven chassis, which keeps the whole machine from overheating. A Quick Tip for the Long Haul Matching the OEM performance is a balancing act. Our lamps put out the same heat flux as the originals, but they can’t do all the work alone. Keep your cooling blowers clean. Seriously. Because these tubes run hot to maintain your cycle speeds, any dust on the reflectors creates a “hot spot.” That’s the fastest way to burn out a lamp. Keep the optics clear, and your quartz will last a lot longer.
