When you need to spec out a heating solution for a high-speed line, you don’t have room for lag or uneven temperatures. We build tungsten halogen infrared lamps specifically for engineers who need to pack serious thermal energy into a tight footprint. These lamps deliver direct, radiant heat that penetrates materials quickly, making them a standard choice for demanding industrial tasks.
Technical Deep-Dive: Power, Voltage, and Dimensions
The core specs of a tungsten halogen infrared lamp are chosen to match the thermal load requirements of the machine. A typical unit might run at 400V and 2500W. This high-voltage, high-wattage combination is engineered to deliver maximum heat density without requiring massive current draw on the line. The trade-off is clear: you get intense, focused heat, but your machine’s cooling system needs to be properly spec’d to handle the ambient temperature rise. The physical dimensions, such as a 300mm tube length, are not arbitrary. This length is a calculated balance between the filament’s resistance and the required radiant surface area. It ensures the lamp produces a uniform thermal profile along the target zone. This allows you to heat a specific area of a component—like a PET bottle parison—without wasting energy on surrounding machinery.
Material and Design: Halogen, Quartz, and Connectors
The filament uses tungsten because it can survive extreme temperatures without failing immediately. We add a halogen gas fill to create the “halogen cycle.” This chemical process redeposits evaporated tungsten back onto the filament, which fights blackening and extends the lamp’s life. The tube itself is made of high-purity quartz. This material handles the thermal shock of rapid heating and cooling, and it remains transparent to infrared radiation, letting the heat pass through efficiently. The connector choice—often an R7s or Sk15—is a practical decision for the shop floor. These double-ended connectors provide a secure, low-resistance electrical contact. They are designed for quick replacement, meaning you can swap out a burnt lamp in minutes rather than hours. This design turns the lamp into a straightforward drop-in replacement, keeping downtime to a minimum.
Application and Performance Benefits
In applications like PET blowing or thermoforming, the tungsten halogen infrared lamp shines. The radiant heat directly targets the plastic, heating it from the outside in. This provides a fast response time, allowing the process to run at high speeds. The lamp’s concentrated output means you can maintain tight temperature control over the heating zone, which translates to consistent product quality. For you, the engineer, the benefit is control. The lamp delivers predictable heat output that you can tune to the process. It handles the thermal load, and the system handles the rest. Just remember the reality of the power density: you need to pair this lamp with a robust thermal management setup to keep the surrounding components from taking a beating. When you wire it up, you are putting a compact heater on the line that can take the heat and keep the process moving.
