Let’s talk about what actually makes this greenhouse heater work.
Here’s the thing: this greenhouse heater is built around a 400V, 2500W halogen infrared tube. We chose 400V for a reason. It plugs straight into the industrial three-phase systems you already have. No extra transformers. No messy, long wiring runs. Just a clean, direct connection. And the size? It’s compact—300mm long, 10mm across. That tight footprint packs a serious punch, giving you high watt density without needing a bigger housing.
The guts of it: built to last
Inside, the quartz envelope holds halogen gas under high heat. That keeps the filament stable and helps it resist burning out too soon. Plus, there’s a reflective coating on the tube. It pushes infrared energy forward, so the heat goes where you need it, not wasted to the sides. And the R7s connector? It’s a simple, two-pin, straight-wire setup built for high temperatures. It wires up fast and stays aligned, making this a true drop-in swap for your existing greenhouse fixtures.
Why this matters in the greenhouse
When you’re heating a greenhouse, you need warmth that’s fast and easy to control, especially for specific plant zones. This heater gives you that—instant infrared heat. You can hold your target temperature without trying to warm the entire air volume. But here’s the trade-off: with 2500W of power, you do need to keep airflow and clearance in mind to protect nearby components. For the folks doing the install and service, the 400V operation, compact size, and R7s compatibility mean less panel complexity and easier field work. It just makes the job smoother.
