Electric Blow Heater: The 400V Halogen Tube with R7s Connector, Built for Industrial Heat
We built this electric blow heater for one reason: to give industrial processes a direct blast of heat, right where you need it, as fast as possible. It’s a halogen tube heater, typically running at 400V and 2500W, designed to pack a huge amount of heat into a small space.
Let’s get into the details
Here’s the thing about the 400V rating. It’s chosen to match the power setup in your plant. That means it pulls less current, so you don’t get that frustrating voltage drop over long wire runs. And that 2500W of power packed into just 300mm? It’s all about focus. You get a rapid temperature rise in those tight spots that need it most. This heater gets hot, fast. So you’ve got to make sure the surrounding equipment has proper cooling and airflow. It’s a powerful tool, and it needs a little space to do its thing without cooking the parts next door.
What it’s made of, and why it matters
The heating element itself sits inside a quartz envelope. This is the stuff that can handle rapid heating and cooling without breaking a sweat, keeping the heat output steady. A reflective coating on the inside throws that infrared energy forward, so more of the heat actually hits the target. And the R7s connector? It’s a simple, secure, high-temp connection that makes installation a breeze. It holds tight, even with constant vibration, so you don’t have to worry about it failing.
Where it shines
This setup is a go-to for blow molding and PET blowing, where you need to heat preforms with serious precision. The shortwave infrared heat gets right in there, fast, which helps you keep cycle times consistent. For engineers, it’s the kind of heat source you can just drop in, wire up, and forget about. It’s simple to install, easy to maintain, and built to handle the heat, over and over again.
