We build carbon heater tubes for engineers who need serious infrared heat—without taking up a ton of space. These are the units you reach for when you need high wattage in a compact package, especially for demanding jobs like PET blowing and plastic pre-heating.
Technical Deep-Dive
These tubes are built for high voltage, typically 400V, and crank out power from 1000W all the way up to 2500W. That voltage rating is a real practical win: it lets you run high power over longer distances without worrying about voltage dropping off along the line. And the sizing? It’s matched to real equipment. You’ll find common lengths like 300mm or 450mm, chosen to fit specific heat zones. You simply pick the wattage and length that line up with the thermal load of your process.
Material & Design
Inside, it’s a carbon filament tucked into a quartz envelope, then filled with halogen gas. That halogen cycle does the quiet, steady work of keeping the filament clean and preventing blackening, so output stays consistent over the tube’s life. The quartz body is tough enough to handle the thermal shock of rapid on/off cycling—no drama when things heat up and cool down fast. We pair these tubes with R7s or Sk15 connectors for a secure, low-resistance connection that stays tight, even when the machine is vibrating.
Application & Benefits
In the real world, these tubes respond quickly and pack a lot of heat into a small footprint, which can help speed up cycle times. They’re also a straightforward drop-in replacement for many standard industrial heaters. But here’s the part to keep in mind: cramming this much power into a small tube creates intense, localized heat. So your machine’s cooling and shielding need to be properly set up—to manage ambient temperature and protect nearby components.
