We built these IR halogen heat lamps for one reason: to keep up with the pace of PET blowing machines. These aren’t just off-the-shelf heaters. They were designed for intense, focused heat, where every second counts and temperature control can make or break the job. Here’s the power and fit, in plain terms. Most run at 2500W and 400V, with a 300mm active length. That combo packs a lot of heat into a small space. And running at 400V means less current draw than a 230V unit. Less strain on the wiring, less energy lost along the line, and a cleaner install. The 300mm length lines up with the neck heater zones on most blow molds, so you can swap it in and get back to work. Now, what’s happening under the hood. The halogen cycle keeps the quartz envelope stable, even when the filament runs hot. That translates to steady output, day after day. The shortwave IR hits the PET preform fast, with almost no wasted energy heating the surrounding platen. And the R7s double-ended connector does its job: it holds the lamp securely, handles the high current, and makes replacements quick and simple when it’s time to change one out. On the line, this is what you feel. You need heat, and you need it to stay put. This setup responds quickly and holds temperature steady, so preforms heat evenly. The trade-off? It’s all about heat density. That means your machine’s cooling and airflow need to be set up right, so the lamp and nearby parts stay within safe operating limits.
