When the heating tunnel starts drifting, you feel it everywhere—scrap piling up, cycles slowing down, changeovers turning into panic drills. You need an infrared lamp that behaves like the original, electrically and thermally, without paying OEM prices to get it.
What matters, technically
This is a 400V, 2500W infrared lamp, built for PET preform heating in stretch blow molding. It holds repeatable output so the heating curve stays steady over long runs, and the 2500W rating lines up with what most OEM heaters are spec’d at. It uses short-wave infrared, so response is quick—tune a zone, and you don’t wait around for the thermal lag to catch up. You get consistent quartz tube clarity and stable filament geometry, which keeps energy density even across the preform shoulder and body. No surprises, just repeatable heat where you need it.
Why it plays well on these machines
On blow molders from Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB, the real payoff is uptime. Stable heat means fewer underheated preforms, less neck distortion, and fewer micro-cracks that only show up later—usually at the filler. You also get an OEM-level fit with a cost structure that makes sense for replacement budgets. In practice, that means fewer emergency spares sitting on the shelf and maintenance windows you can actually plan around. Energy use stays in line because the lamp hits setpoint fast and holds it without oscillation. The tunnel controller isn’t chasing spikes.
The practical details you can’t skip
Installation is straightforward, but you have to verify lamp length, end cap type, and terminal orientation against your blow molder’s heater holder and wiring. Match voltage and wattage, then double-check reflector alignment—mis-alignment shows up as hot and cold bands on the preform. Replace lamps around clean power cycles to protect the filament, and store spares dry and vibration-free.
