Getting Flash Curing Right with the 850mm Quartz Halogen Lamp
When you’re flash curing, you need a massive hit of heat—fast. You want to set those coatings or adhesives instantly without accidentally cooking the material underneath. That’s why we went with this specific quartz halogen setup. It’s a 2000W beast stretched across 850mm, which gives you the kind of linear heat you need for those wide-web lines or oversized parts. The Deal with Power and Voltage We set these to run at 415V. Why? Because in an industrial tri-phase setup, that’s the sweet spot. It lets us hit that 2000W mark without blowing a fuse or drawing too much current. Here’s the thing: if you try to wire this into a lower-voltage circuit, you’re just not going to get the temperature needed for shortwave emission. Plus, that 850mm length is key. It spreads the heat evenly so you don’t end up with those annoying cold spots and uncured patches that ruin a batch. Why Quartz and Halogen? We use high-purity quartz glass because it can take a beating. When you’re cycling heat on and off rapidly, most glass would just crack from the thermal shock. Then there’s the halogen cycle. It stops the tungsten filament from evaporating and gunking up the inside of the tube. This keeps the glass crystal clear. And that’s important—if the tube stays clear, the shortwave IR radiation actually hits your part instead of getting trapped inside the lamp. Making it Work in Your Shop These are designed to slide right into high-speed curing tunnels. The heat-up time is almost instant. But look, there’s a trade-off. Pushing 2000W at 415V creates a lot of radiant heat.A lot. You’ve got to be smart about your reflectors and cooling fans. If your housing isn’t vented properly, the heat soak will eat your wiring or burn out the lamp ends. Just a tip: double-check your connector tolerances before you flip the switch. You really don’t want to deal with arcing at the terminals.
