Our industrial quartz heater tubes are built to slide right in and take over for your infrared heating system in blow molding lines. No custom fittings. No messing around. Just get the line back up to temperature and keep things moving. Power, voltage, footprint—kept simple We tuned these tubes to hit a sweet spot in power density. You get 2500W across a 300mm length, which is exactly the kind of concentrated heat that softens PET preforms fast. And the 400V spec? That’s intentional. It gives you the wattage you need over longer runs without the voltage drop that sneaks in with lower voltage lines, and it keeps the wiring inside the machine from getting bulky. The result is the heat profile you need, without redesigning the whole heating chamber. The guts of the tube: quartz, physics, and smart details At the core is high-purity quartz glass—tough enough for rapid heating and cooling cycles, and excellent at sending out shortwave infrared energy. We add a reflective coating on one side to push the heat forward, so less energy is wasted and the machine’s internal parts stay protected. And the connectors—R7s or Sk15—aren’t random. These bi-pin designs lock in a solid, high-temp connection that can handle the heat and vibration of 24/7 operation. They’re the industry standard for a reason: they work, and wiring them is straightforward. On the floor, where downtime hurts the most Time is money out there. That’s why we build our tubes to match the core mechanical and electrical dimensions used by about 95% of global OEMs. So you can keep our tubes on the shelf, swap out a burnt unit, and get the line running again without waiting on a proprietary part. Here’s the trade-off, though: that high heat density means the machine’s cooling needs to be up to the task. If the cooling can’t keep pace, the surrounding heat will shorten the tube’s life. But when the system is balanced, you get a dependable, high-output heater that keeps unplanned maintenance to a minimum.
