Halogen Shortwave Lamps: The R7s-Powered Heat Solution for Compact Industrial Systems
Let’s talk about a heat source that’s small but mighty. Halogen shortwave lamps are the go-to when you need intense, focused heat in a cramped industrial setup. They’re built for the jobs where space is tight, time is short, and you absolutely can’t afford temperature swings. They get hot. Fast. And they keep it steady.
The Power Behind the Heat
Here’s the thing about how we’ve set these lamps up. They run on 400V, which is a smart move because it keeps the current on the line lower. And lower current means you can use thinner wiring, smaller contactors, and you won’t get that annoying voltage drop over long runs. We’ve packed 2500W of power into a 300mm tube. That’s a serious amount of heat density in a small package. It’s perfect for heating up tiny zones almost instantly. But with that kind of power, you have to be smart about cooling. If you’re cramming this into a small enclosure, you’ve got to make sure your cooling is up to the task. Otherwise, the components inside can get stressed out by the heat.
What Makes Them Tick
The heart of the lamp is a quartz envelope. We chose it because it can handle rapid temperature changes without cracking, and it lets UV light pass through easily. Inside, a clever halogen cycle keeps the filament clean, which means the heat output stays stable over the life of the lamp. We also coat the quartz to manage the infrared heat, so you’re not blasting nearby components with direct radiant heat. And the R7s connector? It’s just a simple, two-pin design that snaps right in. It makes a solid connection every time. It’s a straight drop-in for standard R7s sockets, so you can get it wired and back online without having to rework the whole setup.
Where They Shine
These lamps are all about direct, line-of-sight heating over short distances. Think of things like heating PET preforms, plastic welding, sealing, or heating up a small oven zone. The shortwave energy hits the surface directly, not the air around it. That means way faster warm-up times and much more consistent results. And that compact 300mm length? It gives you serious flexibility when you’re designing your layout. You can squeeze heat into spots you thought were impossible. For you, the engineer, it means predictable performance, easy replacement, and a footprint that actually fits your machine. No fighting with the design. Just reliable heat where you need it.
