We built this digital thermostat heater for engineers who need serious heat—precise, powerful, and in a package that doesn’t eat up your bench space. Forget about it being some all-purpose lamp. This is a tool, pure and simple. A purpose-built industrial heater for the jobs where temperature control can’t be left to chance—like PET blowing. Here’s the power setup: 2500W, running on 400V. We went with high voltage because it gives you maximum heat density, without overloading your plant wiring. And the length? A tight 300mm. It’s a calculated size, giving you a focused heat zone without wasting energy on a bulkier design. Perfect for spot heating where space is tight, but the heat demand is huge. Inside, the core is a halogen-filled quartz tube. It keeps the filament stable and prevents blackening, so you get consistent output over time. And the R7s connector? It’s the standard for many industrial heating fixtures, so it’s a direct, drop-in replacement. It handles the high current safely and makes the wiring quick and straightforward. This heater shines in processes that demand intense, localized heat—PET blowing is a prime example. The digital thermostat gives you tight control over the temperature, which is exactly what you need for consistent part quality. But here’s the reality check: that kind of power density means you need to manage the heat. The 2500W output requires that the surrounding equipment has proper cooling. It’s how you prevent overheating and make sure the heater itself doesn’t burn out too soon.
