We build PTC ceramic heaters for the kind of industrial spaces where heat has to be dense, and it has to be reliable. No ifs, no buts. Here’s the magic: they use a ceramic core with a positive temperature coefficient, which basically means the heater self-regulates. That cuts out the scary risk of runaway temperatures. You get steady, predictable heat without needing to babysit complicated control systems.
Getting into the details
We spec these out at 400V and 2500W, so you get serious heat from a surprisingly small footprint. The 300mm length keeps the hot zone focused, so you can squeeze it into a crowded machine without having to redesign the whole chamber. And because it’s high voltage, the current draw for that power is lower. That means you can use smaller wires and you won’t get that voltage drop over long runs. The end result? Cleaner wiring on the plant floor that’s easier on the budget.
What it’s made of
The envelope is quartz, which handles sudden temperature swings like a champ and keeps the insides spotless. Inside, a halogen fill keeps the filament stable, so the output stays consistent for the life of the heater. The R7s connector is just a simple, two-pin interface. It locks in fast and carries the load without drama. You wire it up, clamp it down, and get back to work.
Where it shines
This setup is built for tough jobs, like PET blowing, where you need heat fast and focused—no overshoot. The PTC behavior gives you a built-in thermal limit, and the 400V/2500W rating delivers the punch you need, even for thicker sections. Just one thing to keep in mind: that kind of concentrated power needs proper cooling and ventilation around the heater. But when the machine and the spec are matched up right, you get performance that feels effortless.
