Swapping Out Mercury Lamps: A Real-World Guide to Our 400V 2500W Halogen Infrared Heaters
We built this lamp to be the simplest, most direct upgrade possible. If you’re stuck with high-pressure mercury lamps in your industrial heating line, this is your drop-in replacement. No messing around with rewiring the whole fixture. The point is simple: get you consistent, powerful radiant heat that responds faster and gives you cleaner control.
Let’s Talk Specs: Power, Voltage, and the Right Fit
This unit runs at 2500W and 400V. That higher voltage is a smart move—it keeps the current lower, which means less voltage drop over distance. In practice, that often lets you get away with thinner wiring in your machine bay. And the 300mm tube length? We chose it because it lines up with the reflector envelopes you’re already using. So you keep your existing hood and mounting hardware. The heat goes exactly where your process needs it, without wasting energy where it isn’t wanted.
Inside the Design: Halogen, Coating, and a No-Fuss Connector
Inside, the halogen cycle does the heavy lifting, keeping the filament stable and the output steady over the life of the lamp. The quartz envelope is coated to shape the infrared spectrum, pushing energy toward shorter wavelengths. That helps surfaces—like plastics and coatings—absorb heat faster. And the R7s connector? It’s just a straightforward two-contact design. On the shop floor, that means termination is quick and repeatable. No headaches.
Where It Shines: PET Blowing and Tough, High-Heat Jobs
For PET blowing and other thermal forming steps, you need surface heat, fast, with tight control. This lamp delivers high heat density, so your cycle times can stay short. That power does mean the surrounding enclosure will run hotter, so make sure your cooling and thermal management are sized to match the wattage density. And if you’re replacing mercury lamps, there’s a big win beyond performance: you get rid of the handling and disposal burden—while keeping the same mounting footprint.
