Getting the Heat Right in Your Husky HyPET System

If you’ve ever dealt with high-speed PET blowing, you know the headache of uneven wall thickness. It usually happens because the outside of the preform gets scorched while the core is still freezing. When that happens, your bottles fail. Simple as that. We built our infrared lamps to fix exactly that. The trick is all about penetration. Most standard IR lamps just dump energy onto the surface. It’s like trying to warm up a frozen steak with a blowtorch—the outside burns before the middle even thaws. We do things differently. We shift the spectral output toward shortwave infrared. This lets the heat actually slide through the PET instead of bouncing off the surface. By tweaking the quartz and the filament temperature, we make sure the heat hits the core without ruining the exterior. No one wants a wiring nightmare. We designed these tubes to be drop-in replacements. They match the OEM KRONES and Husky footprints exactly, so you aren’t spending your weekend rewiring an oven. Plus, we use heavy-duty quartz glass. These things can take a beating from constant thermal cycling without cracking. Then there are the connectors. Honestly, this is where most people run into trouble. A loose connection at 230V or 400V will fry your sockets in a matter of weeks. It’s a mess. That’s why we use precision-fit R7s or Sk15 terminals. They fit tight. No arcing, no burnt sockets. A quick word of caution on wattage. It’s tempting to go for the highest wattage to get faster cycle times. More heat density sounds great, but it puts a lot of stress on your power supply. If you go for max output, just double-check your forced-air cooling. If your oven can’t breathe, the ambient heat builds up. That leads to distorted reflectors and lamps that burn out way too soon. It’s all about that balance. At the end of the day, we just want to give you a lamp that actually penetrates the plastic, cuts down your scrap rates, and slides right into your existing rack.
