A Better Way to Handle Your Krones Contiform 3 Lamps
If you’re running a Krones Contiform 3, you already know the IR oven is where the magic happens. But it’s also where the headaches start. When your lamps start to fade or burn out, everything goes sideways. Your preform temperatures swing wildly, and suddenly you’re staring at bottles with uneven walls or that annoying pearlescent haze. It’s frustrating. That’s why we built our IR lamps to be a true drop-in replacement. No proprietary locking nonsense. No “brand-only” restrictions. They just fit. In fact, they work with about 95% of the blowing machines out there. Getting the heat just right The tricky part with the Contiform 3 is the balance. You need enough heat to hit that glass transition temperature, but not so much that you scorch the PET. We’ve matched our tubes to the exact electrical footprint of the original gear. By using high-voltage setups, we keep the current draw low, which takes the pressure off your power supplies. The real win? Consistent heat. No “cold spots” along the tube, which means way fewer blow-out failures. Built to last (and easy to install) We use heavy-wall quartz glass and fill it with halogen gas. It sounds technical, but here’s what it actually means: the filament can run hotter without evaporating. You get a longer life out of every lamp. And the installation? It’s a breeze. We use standard R7s or Sk15 connectors. You just plug them in. No rewiring the oven, no soldering, no calling in a specialist. Just swap and go. One quick heads-up These are high-output lamps. They put out a lot of heat. Because of that, you’ve got to make sure your ventilation and cooling fans are actually clean and doing their job. If the airflow is blocked, the heat builds up and can stress your sockets or wear out the quartz faster than it should. Keep it breezy, and the lamps will stay happy. The best part is that we actually keep these in stock. You don’t have to deal with those endless OEM lead times that leave your line sitting idle. Just swap the old tube, tweak your heat zones, and get back to making bottles.
