Spec-Out Your Leybold Vacuum Heater with Our High-Spec Infrared Lamps
Here’s the deal: we built a direct-spec replacement for Leybold vacuum heater spares. Our infrared heating lamp is engineered to match the spectral output and thermal response of the big-name brands—without the big-name price tag. You get the same level of process control, just without paying for the brand premium.
The Specs, Straight Up: Power, Voltage, and Size
Our vacuum heater lamps run on 400V, giving you the high electric field strength needed for that intense, fast-response infrared output. Running high voltage means you use less current for the same wattage, which lets you use smaller wiring and keeps those terminal temperatures stable, even when it’s working hard all day. That 300mm active heating length? It’s intentional. It concentrates the energy right where you need it, so you can heat a specific area fast without overheating the whole chamber. And the 2500W rating isn’t just a number. It’s sized to ramp up quickly and hold a steady temperature in a vacuum, where there’s no air to help with heat transfer—it’s all about the radiation. Just a heads up: that’s a lot of heat density, so make sure your machine’s cooling is set up for it.
Inside the Build: Halogen, Quartz, Coating, and R7s Connectors
Inside, the halogen cycle keeps the filament performance steady over the lamp’s life. It works by redepositing evaporated tungsten back onto the filament, which helps prevent premature burnout and keeps the output consistent. The quartz envelope is tough—it handles thermal shock and keeps the vacuum sealed tight. We use a precision infrared coating to control the spectral profile, giving you the exact wavelength distribution you need for proper absorption in vacuum heating applications. And the R7s connector is a no-fuss, industrial termination that seats cleanly and holds up, even through repeated maintenance.
Drop-In Performance for Vacuum Heating
This setup is built for vacuum heater roles—the kind of process heating where you need fast, controllable radiation heat that won’t contaminate the chamber. The lamp is a straight drop-in replacement for Leybold-compatible fixtures, so you can swap it out without rewiring the whole system. Now, a reality check: 2500W at 400V means you need a properly rated power supply and contactor. If your cabinet airflow is on the weak side, those terminal and socket temperatures will climb. But match the lamp to the right cooling and electrical specs, and you get stable output, predictable life, and repeatable cycle performance. All without overpaying for the badge.
