Custom Quartz Carbon Halogen Heating Tubes: Built for the Heat, Built for Your Machine
We make custom quartz carbon halogen heating tubes for industrial setups that need serious heat control in a small space. These tubes are all about packing a lot of heat into a tight spot, responding fast, and holding up when the machine never really stops. You tell us the voltage, wattage, length, and connector you need, and we build a tube that drops right into your existing fixture. No fuss. No rework.
Power, voltage, and size: the numbers that matter
These tubes are rated for 400V and can be built up to 3000W, so you get a lot of heat per inch. A 300mm tube can run at 2500W, which is exactly the kind of punch you want to hit target temperatures quickly on compact zones. High voltage helps here because you get more power without pushing a ton of current. That means smaller conductors and less loss in the wiring. But here’s the trade-off: more power density means more heat to manage. If you run a 2500W tube in a 300mm space, the reflector, socket, and any nearby insulation need room to breathe. Plan for the worst-case ambient, or add active airflow. Otherwise, things run hotter than you expect.
Materials and design: built to take the heat
We use quartz envelopes because they handle high operating temperatures and stay dimensionally stable, even when you heat up and cool down again and again. Inside, halogen gas stabilizes the filament and cuts down on blackening, so output stays consistent over the life of the tube. A reflective coating directs infrared energy forward, so more heat goes where you need it and less is wasted. For connectors, we fit R7s or SK15, depending on your machine’s mounting and terminals. These handle the current and give you solid, repeatable contact. If your line does frequent changeovers, the connector choice matters as much as the tube itself.
Why these tubes shine: tight heat, fast response
These tubes are made for industrial heating where space is tight and cycle time is everything. You’ll see them in PET blowing preforms, plastic welding, shrink tunnels, and component drying. Halogen infrared heating is fast—hit setpoint quickly, then shut down fast when the part moves on. We tailor the length, watt density, and end fittings to match your exact zone layout. That means less redesign on the machine and easy field replacements. Match the spec, wire it up, and run.
One reality check you’ll thank yourself for later
High watt density is powerful, but it needs respect. Plan your airflow and clearances. If you don’t, the tube and the parts around it will run hotter than you bargained for. Do the thermal homework up front, and the machine runs calm and steady.
