Getting Your Heat Right: Sidel Matrix and Nissei ASB 70DP Lamps
Here is the problem when you swap out OEM lamps in a Sidel Matrix or Nissei ASB 70DP: the heating curve likes to shift. If the wattage is off or the light spectrum isn’t quite right, your preforms heat unevenly. Then you’re staring at bottles with weird wall thickness, and suddenly you’ve got a headache on your hands. We build our replacement lamps to match the original benchmarks exactly. No guessing. No “close enough.” The trick to the heat curve It isn’t just about the total wattage. It’s about power density—basically, how that energy actually spreads across the quartz. We dial in the voltage and resistance so the lamp pulls the exact current your machine expects. When the power supply is happy, your controllers don’t have to fight the load. That keeps your cycle times steady and your stress levels low. Quartz and coatings (the nerdy stuff) We use high-purity quartz because these things take a beating with rapid thermal cycling. Since these units rely on short-wave infrared to get deep into the PET plastic quickly, the coatings matter. We make sure ours mirror the original reflectivity. The goal is simple: the heat needs to hit the plastic, not the oven walls. Plus, we use standard R7s or Sk15 connectors. You just pop them in. No rewiring, no fuss. A quick tip for the floor These are true drop-in replacements. You shouldn’t have to spend your afternoon recalibrating the whole oven. But a word of caution: high-wattage tubes get incredibly hot. If your cooling fans are clogged with dust or just plain dying, even the best lamp in the world can overheat the housing. Do yourself a favor and check your airflow before you install the new ones. It’ll save you from a premature burnout.
