It&rsquo;s a compact halogen infrared lamp that zeroes in on the preform, hitting it with heat exactly where you need it, exactly when you need it. It slips right into automated lines without taking up a ton of space, and it delivers <a href="https://o-yate.net">steady</a> heat without the bulky feel of those big convection heaters.</p> <h2 id="the-heart-of-it">The Heart of It</h2> <p>At the core is a 400V, 2500W halogen element. Running at 400V lowers the current draw compared to 230V, which keeps wiring manageable and cuts down on heat loss in the lines. The 300mm length wasn&rsquo;t chosen by accident. It lines up with the standard zone length on most blow molding heads, so the heat profile <a href="https://o-yate.com">covers</a> the preform evenly. You get the rapid heat rise you need, but keep in mind: that power density means the surrounding equipment needs to be ready for the thermal load.</p>
