Getting the Heat Right: Sidel Matrix Infrared Lamps
Here is the problem when you swap out OEM lamps in a Sidel Matrix or SIPA SFR 12: the temperature curve loves to shift. It sounds like a small thing, but if the wattage or the light spectrum is even a tiny bit off, your PET preforms won’t heat evenly. You end up fighting the machine all day. That’s why we built our replacement lamps to be a dead ringer for the originals. We wanted the heat distribution to feel exactly like it did the day the machine left the factory. The nitty-gritty on the specs We don’t do guesswork. To keep your temperature ramp steady, we mirror the voltage and wattage footprints of the Sidel units exactly. Why? Because power density matters. If you drop in a lamp with a slight variance in ohms, you change the current draw. That shift messes with the infrared wavelength, which changes how deep the heat actually sinks into the PET wall. We keep those variables locked down so you don’t have to deal with annoying “cold spots” in your preforms. Fit and feel We use high-purity quartz and specific halogen fills to handle the heat load. And the best part? The connectors are a perfect match. Whether you’re dealing with R7s or those specialized Sidel pins, you just drop them in. No messing with the wiring harness, no “making it fit.” We even calibrated the tube coating to make sure the heat hits the preform—not the machine frame. Real-world talk Because these are a 1:1 match, you can keep your oven settings exactly where they are. No need to spend hours recalibrating every single zone. But a quick heads-up: any shortwave IR lamp is only as good as your power. If your grid spikes, you’ll burn through filaments fast, no matter who made the lamp. Keep your regulators tight, and these tubes will last you a long time.
