Getting Your Krones S24 Heating Right (Without Breaking the Bank)
If you’re running a Krones Contiform S24, you know the drill. Those infrared lamps are the heart of the operation—they get your PET preforms soft and ready to blow. But when the OEM lamps finally give out, the replacement bill can be a real gut-punch to your maintenance budget. We’ve fixed that. We make a drop-in replacement lamp that hits the exact same thermal specs as the original, but it won’t cost you a fortune. The Power Stuff Here’s the thing: to get that PET to the right temperature quickly, you need serious wattage. Our lamps are built for that high-voltage push. You get the same heat flux and radiative power as the factory units, so your cycle times don’t budge. Just a heads-up—keep an eye on your power supplies. If you’ve got voltage spikes jumping around, it’ll kill any halogen tube, no matter who made it. Built to Last We use heavy-wall quartz glass because these things take a beating from constant heating and cooling. Whether you need R7s or Sk15 connectors, they fit tight. That’s important. A loose connection leads to arcing, and before you know it, you’ve fried a socket. Some of our versions even have a special coating. It basically tells the heat, “Don’t waste your time on the oven walls—go straight into the plastic.” Swapping Them Out Replacing these is a breeze. We’ve dialed in the dimensions to the millimeter, so you just pop the old one out and slide the new one in. No tinkering with reflectors, no modifying the oven. Simple. One last tip from the field: check your ventilation. High-density heat is tough on a machine. If your cooling fans are choked with dust, the ambient temperature climbs and your lamps will burn out way faster than they should. While you’re in there changing the lamp, give your reflectors a good clean. It’s a small step, but it keeps everything running efficiently.
