Stop Overpaying for Krones Contiform Heating Lamps
Let’s be honest: keeping Krones blow molding lines running is expensive. Especially when you look at the bill for OEM replacement parts. It starts to feel like a tax just for keeping your machines alive. We figured there was a better way. We make drop-in replacement infrared lamps that hit the same factory specs as the originals, but they won’t drain your maintenance budget.
How the heat actually works
To get a PET preform to blow correctly, you need heat that’s fast and uniform. If it’s uneven, your wall distribution goes sideways. We use shortwave halogen tech to fix this. Basically, we pack high-wattage filaments into a tight quartz envelope. This creates a massive burst of heat density that punches right through the PET without melting the surface. Since every Krones power grid is a bit different, we match the voltage and wattage exactly to your setup. By using high-voltage configurations, we can push more power through a single tube. That means you don’t need as many lamps crammed into each oven zone.
No headaches, just plug and play
Nobody wants to spend their weekend rewiring a machine. That’s why we use R7s or Sk15 connectors. They just slide right into your existing sockets. Simple as that. The quartz glass is also treated so it doesn’t crack when the temperature swings wildly during rapid cycling. And if you’re worried about your machine frame getting too hot, we’ve got coated versions. These act like a mirror, bouncing the infrared energy toward the preform and away from the oven walls. It keeps the internals much cooler.
A few pro tips for the floor
These lamps work exactly like the OEM parts—same thermal profile, same lifespan. But here is a heads-up: When you push high wattage in such a small space, your cooling blowers have to work harder.**Check your ventilation filters.**If they’re clogged, your lamps will burn out way faster than they should. Also, don’t swap every lamp in the oven at the exact same time. I recommend a staggered replacement schedule. It keeps the heat consistent across the whole oven and prevents those annoying “cold spots” that mess up your bottles.
