Getting Heat Where It Actually Matters in High-Speed PET Blowing

If you’re running a Krones Contiform 3 Pro or a Husky HyPET, you already know the struggle. You’re trying to get the center of that preform hot enough to blow, but by the time the core is ready, the outside is practically scorching. It’s a frustrating balancing act. That’s exactly why we built our replacement lamps. We wanted to stop the surface burn and actually get the heat deep inside.

Fixing Those Annoying Heat Spots in Your Krones Contiform 3

There’s nothing more frustrating than pulling a batch of bottles and seeing that cloudy pearlescence or thin walls. It’s a waste of plastic and a waste of time. Usually, when you’re running a Contiform 3 and the bottles aren’t coming out right, it’s because the heat isn’t hitting the preform evenly. Either the lamp’s output has drifted, or the quartz glass is just worn out. Either way, you’re fighting a losing battle with your scrap rate. Getting the heat right We didn’t want to just make “another lamp.” We built these to mirror the exact wattage and voltage of the original Krones units, but we focused on the guts of the thing. By tweaking the tungsten filament and the gas mix inside the tube, we made sure the infrared heat actually hits where it needs to. No more “cold spots” in the middle of your preforms. It just works. And because we use high-voltage setups, we can keep the lamp compact without losing any of that raw heating power. The nitty-gritty stuff We use high-purity quartz because these things take a beating. They heat up and cool down fast, and cheap glass just cracks under that kind of stress. We also added a specific coating to the glass. It basically nudges the light spectrum toward the exact wavelengths that PET loves to absorb. Plus, the R7s and Sk15 connectors are machined perfectly. They snap in tight. No loose connections, no arcing, and no burnt-out ends. A quick heads-up for the shop floor These are drop-in replacements. You can swap them out without touching your wiring. Simple. But here’s the thing: if you’re using higher heat density lamps to push your cycle speeds, your oven is going to get hot. Really hot. If your cooling blowers are clogged with dust or acting up, it doesn’t matter how good the lamp is—you’ll just overheat the housing. I’ve seen it happen plenty of times. Before you pop in the new tubes, do yourself a favor and check your fans. Make sure they’re breathing properly so you actually get the speed boost you’re paying for.

Introduction

Let’s talk about the Krones Contiform ceramic base lamp. It’s a direct-fit infrared heater made for PET blow molding lines. And it was built for one specific headache: upgrading older machines without a total overhaul. The whole idea is simple. Swap in the new heater. Get the line back up and running. And boost your output without tearing the machine apart.

Technical Deep-Dive

Here’s the core of it: we packed a lot of power into a small footprint. The Contiform runs on 400V and cranks out 2500W. Why does that matter? Because that combo delivers intense, focused infrared heat—fast. That means you slash the pre-heat time on every cycle. And the lamp is 300mm long. That’s a standard size, so it drops right into the existing heater housing. No new brackets to fabricate. No rewiring the control panel. You just keep the same footprint and move on.
