Technical Deep-Dive: Power, Voltage, and Dimensions
Let’s get into the details of this electric blow heater. We’ve set it up as a 400V, 2500W halogen quartz tube, and it’s 300mm long. That 400V rating is a smart move. It keeps the current on the line lower, which means you get less voltage drop and can use smaller wires inside the machine. And the 2500W? It delivers the kind of heat density you need to get PET heating up to speed fast, so your cycle time doesn’t drag. The 300mm length is a standard fit for many blow molders, so it’s a simple, drop-in replacement.
Material and Design: Halogen, Coating, and R7s
Inside the quartz tube, the halogen element is what keeps the output steady over time. It fights off the blackening that kills the output on regular incandescent lamps. The quartz body itself is tough. It handles the shock of rapid heating and high temperatures without cracking. A reflective coating on the tube focuses all that energy forward, so the heat goes right onto the parison instead of getting lost into the machine frame. And the R7s connector? It’s a proven, straightforward bi-pin fit for this wattage. Makes wiring it up and swapping it out on the shop floor a breeze.
Application and Benefits: PET Blowing
When you’re running PET blow molding, the heater has to do three things: hit temperature fast, hold it steady, and take the repeated heat cycles in stride. This 400V, 2500W, 300mm setup delivers that rapid response and consistent heat. The payoff is stabilized wall thickness and less scrap. Just a heads-up, though. That high power density means you need to make sure you have enough airflow and proper heat shielding around the lamp.
