Glovebox Infrared Heaters: Built for the Moment When You Can’t Afford a Glitch
We make glovebox infrared heater elements for one simple reason: you need heat you can trust inside a sealed space where a failure just isn’t an option. These shortwave infrared lamps are the heartbeat of critical processes, and their reliability doesn’t begin on your production floor. It begins with a 100% dielectric strength and insulation test on every single tube before it ever leaves our hands.
Power, voltage, and the real-world squeeze
Glovebox heating asks for a lot of heat in a very small footprint. So we design these elements to respond fast—often delivering around 2500W—so the process zone hits temperature quickly. Why run at 400V? Because higher voltage lets you push serious power through a compact quartz envelope without needing a thicker, heavier filament. And the size? Around 300mm is intentional. It matches standard glovebox port spacing and internal clearances, so you get a drop-in fit that doesn’t turn into extra rework.
What’s inside—and why it matters
At the core is a high-purity quartz tube, chosen because it handles thermal shock well and stays steady in the shortwave infrared band. Inside, a halogen fill gas helps keep the filament healthy—reducing blackening and keeping output consistent over thousands of hours. On the outside, a reflective coating pushes energy forward. That means more heat goes where you want it and less is wasted heating up the glovebox walls. Then there’s the connector choice. R7s and SK15 terminals give you solid, two-point contact that can handle high current without loosening or arcing. And when it’s time to replace one, it takes minutes, not hours.
Controlled heat. Engineered safety.
Inside a glovebox, you need heat that doesn’t introduce contamination or risk a breach. Our infrared elements deliver non-contact heating, so the thermal load stays separated from the chamber itself. And because every tube gets 100% dielectric strength and insulation testing before it ships, you can count on it meeting the electrical safety demands of serious equipment. One practical note: packing high wattage into a compact tube does create concentrated heat. So your glovebox cooling and thermal management need to be properly matched, to keep everything around it within safe operating limits.
