Keeping Your Krones Contiform S Running Without Breaking the Bank
If you’re running a Krones Contiform S, you already know the drill. It’s a constant fight against lamp burnouts and the sheer cost of keeping the machine humming. It gets expensive. Fast. That’s why we made our infrared lamps as simple, direct drop-in replacements. You get the same heat output as the OEM parts, but without the “name brand” price tag that eats your margins. The deal with power density Here’s the thing: these machines need high-wattage shortwave lamps to soften PET preforms in a heartbeat. There’s no room for “almost.” If the wattage dips even a little, you’ll start seeing cold spots. That leads to uneven walls or that annoying pearlescent haze in your bottles. Nobody wants to ship a bottle that looks cloudy. We spec our tubes to handle the high voltage of your oven so your bottles come out crystal clear every time. Better glass, better fit We use heavy-wall quartz glass. Why? Because when things get blindingly hot, cheap glass bows. Ours stays straight. Most of our units use R7s or Sk15 connectors. They’re the industry standard for a reason—they click in securely and stay stable. No arcing, no loose connections, even when the machine is vibrating at full tilt. Plus, we offer coated versions. These shift the infrared spectrum so the PET absorbs the heat more efficiently. It means the heat goes into the plastic where it belongs, instead of just baking your oven frame. A few tips on installation Swapping these out is easy. Pull the old tube, wire in the new one, and you’re back in business. But a word of caution: if you’re pushing for maximum heat to crank up your cycle speeds, your cooling fans are going to work overtime. Keep an eye on your ventilation. If your filters get clogged with dust and debris, the ends of the lamps will overheat and pop. We build these to take a beating in 24/7 production environments. You get the same thermal footprint you’re used to, just with a much lower cost per bottle.
