The Specs: Power, Voltage, and Size
Here’s the deal with this IP65 waterproof heater: it’s tough, and it packs a serious punch into a small space. We built it to run at 400V, so it slots right into standard industrial lines. You get 2500W of power from a slim 300mm quartz tube. That combo means it heats up fast and holds steady, which is exactly what you need on an automated line. The 300mm length keeps the footprint small, so it slips into tight spots on blow molding or thermoforming gear. But packing this much wattage into a short tube creates serious heat density. So, just keep in mind: the surrounding machinery needs enough cooling and airflow to keep the ambient temperature in check.
The Materials and Design: Why Quartz and R7s
Inside, you’ve got a halogen-filled quartz envelope. Quartz is great because it handles sudden temperature shifts without cracking, and it sends infrared energy cleanly. That means your target gets direct, efficient heating without a lot of wasted convection. The halogen cycle also keeps the filament stable, so you don’t see the output fade over time. We topped the tube off with an R7s connector. It’s double-ended, makes solid contact, and handles the current safely. Plus, it makes the unit a simple drop-in replacement for existing R7s heaters. And the IP65 sealing? We get there with high-temperature gaskets and a fully enclosed end cap. That design stops water from getting in during washdowns and in humid plant conditions.
Where It Shines and What It Means for You
This setup was made for wet or dusty industrial environments—think PET blowing and packaging lines. The IP65 rating keeps water and dust out, so you cut down on maintenance caused by shorts and corrosion. The high watt density heats preforms and molds quickly, which helps you keep cycle times tight. Installation is straightforward. Wire it to 400V, mount the 300mm tube, and line up the R7s contacts. The one thing to watch is thermal load. Make sure your machine’s cooling is sized right so the heater stays within its temperature limits and keeps running smoothly.
