Quartz Electric Heaters: The Real Deal for Industrial Heat
We built these quartz electric heaters for engineers who need serious heat in a small space. Forget the standard element heaters. These are shortwave infrared lamps—built to deliver raw, focused power exactly where you need it.
Power, Voltage, and Fit: Getting the Details Right
Here’s the thing about these heaters: it’s all about the balance—wattage, voltage, and size. Take the 400V, 2500W setup. It’s a go-to for industrial machines because it pulls less current than a 230V unit of the same power. Less current means less strain on your wiring and contactors. And that 300mm tube length? Totally intentional. It slips into tight spots—like blow molding heads or thermoforming tools—so the heat lands right where the process needs it.
Built to Last: Materials That Matter
The quartz envelope handles the extreme heat needed for shortwave infrared. Inside, the halogen cycle keeps the filament clean, so the lamp stays bright and consistent over its life. We also added a gold coating on the tube. It reflects infrared energy back onto the target, which boosts efficiency. And the connectors? We use R7s. They give you a solid, two-point contact that locks the lamp in place and handles high current without getting hot.
Where They Shine—and What to Keep in Mind
These heaters are workhorses for PET blowing, plastic welding, and oven heating. They heat up fast, which keeps cycle times moving. But there’s a trade-off. That high power density means your cooling system needs to be up to the task. The good news? It’s a drop-in replacement for standard industrial lamps. You get reliable performance without redesigning your equipment.
