When the blow molder is running, the heating tunnel has to deliver repeatable preform temperature—every single cycle. A mismatched lamp throws off the curve, and you start seeing thin necks, blown shoulders, or thickness that drifts from shot to shot. We built our 1000mm infrared heating tube as a direct 1:1 swap for the emitters used on Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB machines. The point is simple: stop guessing, and get back to stable output.
What matters, technically
This is a 1000mm quartz infrared emitter, engineered to match OEM dimensions and thermal behavior. Typical configuration is 230–240V, with power matched to the original blow molder spec—commonly 1.8–2.0 kW per tube—so the heating profile in your tunnel stays the same. The R7s double-ended base sits right in the standard lamp holder, and the quartz envelope is chosen for fast response and consistent radiant output across the preform wall. We hold output tolerance to ±3%, because even small drift shows up as weight variation and cycle instability.
Why it holds up on the line
On the floor, heat has to repeat shift after shift. These tubes match the length, wattage, and spectral output of the originals, so you can swap them in without re-tuning the entire heating zone. That translates into fewer startup scraps, fewer thickness swings, and more uptime. Energy use stays aligned with the machine’s original design because the emitter delivers the same heat flux with the same response—no overshoot, no cold spots.
The practical details
Installation is straightforward: clean the holder, verify voltage, and make sure the R7s contacts are aligned. But the lamp only performs as intended when the reflector is clean and undamaged. Operating life depends heavily on voltage stability and ambient temperature; if you’re in an area with frequent voltage spikes, pair the tube with a stabilizer. Plan replacements during scheduled stops, and always confirm the exact wattage and voltage stamped on your machine’s nameplate before ordering.
