The IR Lamp That Actually Saves You Headaches on Your PET Line
Let’s talk about your Krones Contiform system. Specifically, the moment when the original-equipment IR lamp quotes start rolling in. You know the feeling—the budget gets hammered, and the lead times feel like they’re stuck in slow motion. Here’s the good news: we build shortwave infrared lamps that are a straight swap for those Contiform systems. They deliver the same performance, hit the same marks, and don’t force you to rework the whole machine. Just pop them in and get back to work.
The Power Behind the Heat (Without the Drama)
Contiform stretch-blow operations need heat that’s fast, focused, and right where you need it. Our lamps match that energy with 400V operation and power ratings that pack serious heat density into a compact space. The tube length is cut to match the heating zone perfectly. So you get the same thermal coverage without fiddling with brackets or realigning anything. Now, a quick heads-up on the electrical side. That 400V setup keeps current draw lower for a given wattage, which eases the strain on your conductors and helps the control behavior stay steady. But higher voltage also means the lamp runs hotter at the terminals. **Just make sure your reflector airflow and holder materials can handle the heat.**If they’re not rated for the temperature, you’ll end up with premature connector wear—and nobody wants that.
Built to Handle the PET Grind
We chose a quartz envelope because it responds quickly and can take the shock of repeated start-stop cycles without cracking. A special coating keeps the output spectrum on point and shields the filament from contamination. The payoff? Consistent radiant heat and stable output, shift after shift. The connector is designed as a direct-fit for Contiform lamp holders. Installation is simple: swap the lamp, wire it up, and set the machine parameters. The terminals are built to survive repeated thermal cycling without losing spring tension or creating hot spots.
Real-World Results on a Krones Contiform Line
On a Contiform line running PET bottles, this lamp drops in and just works. It hits operating temperature fast, supports stable stretch temperatures, and stays repeatable across shifts. That means fewer rejects tied to temperature swings and less unplanned downtime. You get original-level heating performance with a lower total cost of ownership. The trade-off? The high heat density means your cooling and insulation need to be in good shape. If they aren’t, the lamp will run hotter than it should, and its life will shorten. Do the quick check on airflow and insulation, run the numbers, and you’ll see it: a practical way to cut maintenance spend without slowing down throughput.
