We built this replacement lamp for the Nissei ASB 70DP to match the original down to the last detail. Because on a blow-molding line, when the heater goes down, the whole line stops. That’s not a small hiccup—it’s a full stop. This is a 400V, 2500W halogen lamp, 300mm long, wired for R7s connections. It’s meant to drop in and run, keeping the machine’s thermal behavior exactly as it should be. No fuss. No re-tuning. Here’s the thing about the power: 2500W isn’t a random number. It’s what the process needs to hit the right temperature fast, and hold it steady while the machine is running hard. And the 400V? That voltage was chosen to deliver that power with lower current. Less current means less voltage drop across the wiring and less heat building up at the terminals. The control cabinet stays cooler, and the connections stay happier. Just make sure your supply matches the voltage tolerance. The 300mm length is a strict footprint. If the tube is too short, you get cold spots and uneven stretch. Too long, and it won’t seat right, which can cause contact problems and uneven heating. This length is the sweet spot. Inside, you’ve got a halogen element sealed in a quartz envelope. The halogen chemistry keeps the filament stable at high heat, which fights blackening and keeps the output steady over time. Quartz handles the shock of rapid cycling and sends infrared energy through cleanly. The R7s connector is a double-ended, linear contact design. It gives you solid contact at both ends, so installation is quick and repeatable. It makes the lamp a true drop-in—no need to rework the holder. On a PET blow molder, this lamp heats the preform surface evenly, so the material stretches predictably. High heat density means fast warm-up and tight temperature control, which keeps cycle times stable and bottle quality consistent. Because the lamp matches the machine’s original thermal profile, it helps you dodge unplanned stops. Now, there is a trade-off. At 2500W, the lamp needs clean airflow and a properly maintained cooling path. If the blower is clogged or airflow is weak, the lamp runs hotter—and that shortens its life. We give you the exact form, voltage, and interface so your maintenance team can wire it in and get back to production. Straight in, powered up, and back to work.
