On a Sidel stretch blow molder, uneven preform heating shows up fast—thin walls, crystallized necks, and bottles that just miss spec. The heating tunnel needs an emitter that repeats the same energy profile, shift after shift. The Sidel 2000W quartz heating tube is built for that reality.
What matters, technically
This is a short-wave infrared quartz tube, rated at 2000W and engineered to match Sidel blow molding machines that run on 230V service. The quartz envelope transmits IR efficiently, and the filament geometry is chosen to put the heat where you need it—right across the preform surface—instead of wasting it in a broad spread. In practice, that translates to faster temperature recovery after a bottle change and tighter control over the heating curve. The R7s base and standard dimensions line up with OEM mounting, so you can swap out a worn emitter without reworking the tunnel.
Why it holds up on a Sidel
Sidel blow molders live and die on consistent preform heating—without it, you lose cycle time and you lose bottle quality. The 2000W quartz tube delivers the output needed to bring heat back quickly between shots, which helps keep the heating profile stable even when you’re running different colors or wall thicknesses. That stability cuts scrap from temperature-related defects and keeps the line moving at planned throughput. Energy use stays under control because the emitter targets the preform directly, not the machine frame and the surrounding air.
The shop-floor details
Installation is straightforward, but you have to seat the tube squarely in the reflector and secure it to the specified torque. Misalignment will give you uneven heating and it will shorten lamp life. Verify voltage at the terminal, and make sure the reflector is clean and undamaged—pitting or oxidation changes the spot pattern. Under normal duty cycles, expect service life in the 5,000–7,000 hour window. Keep spares on hand for planned changeovers, so unplanned downtime doesn’t catch you short.
