Keeping Your Krones Contiform Blow Molders Running Smoothly

If you’ve spent any time managing PET preform ovens, you know the struggle. It’s a constant tug-of-war between pushing for faster cycle speeds and trying to keep your energy bills from skyrocketing. On a Krones Contiform line, the IR radiator bulbs are the parts that take the biggest beating. When those bulbs start to dim or burn out, you’ll notice it immediately in your bottles. You get those annoying thin spots in the walls that make the whole batch look off. That’s why we made our replacement radiators simple. They’re direct drop-ins. You swap them out, save some money on maintenance, and get your heat distribution back to where it should be. Let’s talk power. These things run on high voltage—usually 230V or 400V—to get the wattage needed to heat preforms fast. We use a compact quartz tube to create that intense, short-wave infrared radiation that actually penetrates the PET. But here is the catch: you have to match the voltage to your machine’s transformer exactly. If you get it wrong, you’re looking at one of two problems. Either the preforms won’t get hot enough, or you’ll blow the filament in a matter of minutes. Not a great way to start a shift. The gear inside We use heavy-wall quartz glass because these bulbs go through a lot of thermal shock during rapid cycling. Most of our units use R7s or Sk15 connectors. We stick to these standards so the bulb sits perfectly in the socket. No wobbling, no arcing, no headaches. Some of our versions even have a special coating. Instead of letting heat bleed backward into the oven housing, it pushes everything forward into the preform. It’s a simple tweak, but it makes a huge difference in heat density. One last thing… A high-output bulb is great, but it puts a lot of pressure on your cooling system. If your ventilation is clogged with dust or your fans are on their last legs, these bulbs will run way hotter than they’re supposed to. That’s the fastest way to kill a filament. Before you wire up a new set of radiators, just take a second to make sure your airflow is clear. It’s a small step, but it’s the only way to make sure your quartz lasts as long as possible.

Stop the Glare: Making Bathroom Heaters Actually Comfortable

Ever stepped into a bathroom with one of those infrared heaters and felt like you were staring directly into the sun? It’s a common problem. Most of these lamps use short-wave radiation to get you warm fast, but they come with a side effect: a harsh, blinding white light. If you’ve got kids or babies in the house, that glare isn’t just annoying—it’s way too intense for their developing eyes. We decided to fix that.

Sidel Infrared Radiator Module: The Tough Drop-in for SIG Blomax Lines

We built this Sidel infrared radiator module for one reason: to stop those frustrating tube failures on your SIG Blomax PET blowing line. It’s a structurally reinforced, long-life replacement that drops right in and keeps your line moving.

The power, voltage, and fit—explained like you’re standing next to the machine

We set it up to deliver steady heat without taking up extra space. The 400V input means lower current for the same wattage, so the wiring stays cooler and you lose less voltage along the way. The 300mm length lines up perfectly with the standard hot zone on Blomax machines. That gives you even heating across the bottle neck—no messing with the reflector cavity. And the wattage is tuned for PET stretch blowing, so the preform hits the right temperature right before the blow pin engages.

Krones Contiform white coating IR radiator

On a Krones Contiform blow molder, uneven preform heating shows up fast—off-center bottles, blown-out shoulders, and a line that never stops chasing setpoints. We built our Contiform white-coating IR radiator as a straight swap for the OEM heating element: same geometry, same output, so the heating tunnel runs the way the machine was designed. The core is short-wave infrared inside a white-coated quartz envelope, sized and wired for the Contiform tunnel and standard lamp holders. The white coating shifts the emission curve, cutting down on glare and evening out reflector surface temperature. That helps keep the preform skin temperature profile repeatable. We match the original lamp wattage and length, and spec the filament layout and terminals so the power delivery lines up with the machine’s control strategy. Here’s what that buys you on the floor. Stable heating lets you hold stretch blow molding windows without constantly trimming offsets—less scrap, and cycle time stays where it belongs. Energy use drops because the emitter hits target fast and holds it with tight control, and the white coating keeps the heat focused where it needs to be. Replacement is straightforward—same mounting, same connections—so downtime stays short. Installation note: keep the reflector clean and dry, and make sure the lamp seats squarely in the holder. On Contiform lines that run hot and dusty, set a regular inspection interval. If the reflector degrades, heating uniformity drifts.
