Getting the Heat Right for Husky HyPET Systems

If you’ve spent any time with high-speed PET blowing, you know the struggle. You’re pushing for speed, but the heat just won’t get where it needs to go. The surface of the preform gets scorched, but the core stays cold. Then, the moment you blow, you get uneven walls or—even worse—bottles that just burst. It’s frustrating. That’s exactly why we built our infrared bulbs the way we did. We wanted to fix that “cold core” problem for anyone running Husky HyPET setups.

Stop Overpaying for Krones Contiform IR Lamps

If you’re running Krones Contiform machines, you know the drill. Those PET preforms have to hit a very specific temperature before they blow, or everything goes sideways. But here’s the annoying part: when the OEM lamps burn out, the replacement bills start to feel like a punch to the gut. We figured there was a better way. We make IR lamps that do exactly what the original ones do, just without the “brand name” tax. The nitty-gritty on heat and power These lamps live in a high-voltage world. To get that intense heat in such a small space, we use quartz glass that can handle the constant stress of heating up and cooling down. We match the voltage and wattage of your original Krones setup exactly. Why? Because the last thing you want is to fry your power supplies. Just a heads-up, though: when you’re pushing this much heat in a tight oven, your cooling fans need to be spotless. If they’re clogged with dust, your circuitry is going to feel it. Why quartz actually matters We use halogen-filled quartz tubes. It sounds technical, but it basically means the lamp can run hotter for longer without the filament giving up the ghost. We also coat the tubes to shift how the heat hits the plastic. Instead of just scorching the surface of the PET, the heat actually sinks in. And the best part? They use standard R7s or Sk15 connectors. No rewiring. No modifying the holders. No headaches. You just pull the dead lamp out, plug the new one in, and you’re back in business. What this means for your day-to-day At the end of the day, it’s about the bottom line. You get the same heating curve and the same cycle times, but your cost per bottle drops. These machines are brutal on parts—constant on-off cycling is a lot of stress. Our lamps are built to take that beating. Just make sure your contacts are tight during installation so you don’t deal with any annoying arcing at the base. Simple as that.

Getting the Heat Right in Your Husky HyPET System

If you’re running high-speed Husky HyPET systems, you already know that throwing more wattage at your preforms isn’t the answer. It’s not about raw power. It’s about where that heat actually goes. The real struggle is getting the heat into the thickest parts—the base and the neck—without accidentally scorching the thin walls. That’s where we spend most of our time. We build our IR lamps to hit that exact sweet spot where the plastic actually absorbs the energy. The trick to deep penetration To get the heat deep into the plastic, we play around with the quartz composition and the filament tuning. Now, short-wave IR has a lot of punch, which is great for fast cycles, but it can be a bit too aggressive. We balance the spectral output so the heat doesn’t just sit on the surface. It needs to drive straight into the core. If it doesn’t, you end up with a “cold core,” and that’s exactly how you get uneven wall thickness in your finished bottles. Nobody wants that. Built for the Husky footprint Our lamps are designed to be simple drop-in replacements. No fuss. We use heavy-duty quartz glass because blowing plants are brutal on equipment, and the rapid thermal cycling can crack cheaper glass. We also make sure the connectors are tight. A loose connection means voltage drops, and that kills your efficiency. One quick tip: if you’re running high-wattage tubes, keep an eye on your power supply. More heat in the preforms means a hotter oven. If your cooling blowers aren’t up to the task, you’re just asking for your lamps to burn out early. The reality of the shop floor These lamps will definitely shave time off your cycles because they deliver heat faster. But there’s a trade-off. Higher heat density means those filaments are working overtime. If your voltage is jumping around, you’ll see a shorter lifespan. Keep your power stable, and you’ll get way more hours out of every tube. We handle the physics of penetration so you can just speed up your line and stop worrying about scrap rates.
