What’s really going on under the hood
We built the Sunlike infrared heater as a shortwave halogen tube, because when you need heat, you need it now. It delivers high-density heat on demand, without fuss. It runs on 400V, so you can power longer heaters straight off standard industrial supplies—without the wiring having to work overtime. Packed into a 300mm length is 2500W, which means serious watt density. That’s why it heats up fast and snaps back to temperature after a door opens and closes. And the compact size? Perfect when your space is tight and every inch counts. One thing to keep in mind: that kind of power in that small footprint means your machine needs solid cooling and thoughtful thermal management. Keep the airflow and guarding matched to the heater, and it just works.
The materials and design that make it reliable
Here’s the thing with halogen: the halogen cycle keeps the filament stable. So you get steady output over the life of the heater, and it doesn’t throw in the towel when the on/off cycles keep coming. The quartz envelope handles thermal shock like a champ, and the reflective coating pushes the energy forward—so less heat goes sideways, and more goes where you need it. The R7s connector? Simple, proven, and it makes replacement quick. It holds contact securely, even when things vibrate. If you’ve already got machines with R7s, this is a straight swap—no hassle, no rework.
Where it shines—and what it feels like to use
Use these heaters wherever you need fast, focused heating: PET blowing, thermoforming, curing, plastic welding—you name it. The shortwave output hits fast and penetrates quickly, heating the part surface without turning the whole machine into an oven. What you feel on the line is the pace: cycles move faster, temperatures stay steady, and maintenance stays simple. Now, it’s true—this is high heat density. So your guarding, airflow, and temperature sensors need to be on the same page as the heater. Set that up, and you get the upside without the trade-offs.
