Replacement lamp for SIPA SFR 16 rotary

Introduction

We built this infrared heating lamp to be a straight-up, drop-in replacement for the SIPA SFR 16 rotary system. The idea was simple: make a lamp that not only meets the original specs but also works across most global blow-molding setups. This thing was made for the shop floor, not for sitting pretty in a showroom.

What’s Under the Hood: Power, Voltage, and Size

At its heart, this unit runs on a 400V, 2500W setup. That’s not by accident. The high voltage packs a serious punch into a compact 300mm quartz tube, giving you the intense heat you need to quickly warm up PET preforms. That 2500W rating means the lamp can handle the heat of non-stop production without the output dipping. But, and this is important, that kind of power density means your machine’s cooling system has to be up to the task. If the area around the lamp gets too hot, you’ll shorten its lifespan.

SIPA SFL blowing machine heater manual

On a SIPA SFL line, preform heating is the one bottleneck you can’t afford to wing. When the heater isn’t right, temperature drift shows up fast—cycle-to-cycle weight swings and amperage spikes that drive the cabinet thermals hard. The SIPA SFL blowing machine heater manual isn’t paperwork for its own sake; the heating tunnel is built around a specific infrared profile, tuned to be stable, repeatable, and matched to the machine’s power and control logic. What matters, technically We build the replacement to the SIPA SFL spec: short-wave halogen infrared emitters with quartz tubes and R7s connectors, sized to match the OEM mounting and focal distance. Watt density is matched to the original so every station delivers the same heat flux to the preform. The heater body uses high-temperature ceramics and reflectors to keep the energy on the preform, not bleeding onto adjacent parts. Voltage and termination match the machine harness, so commissioning is plug-in, not a rewire job. Why it holds up on an SFL The SIPA SFL is designed around a heating tunnel that expects a precise infrared spectrum and response time. When you install a heater that meets the manual’s parameters, you restore the intended preform temperature curve, which stabilizes stretch ratio and wall distribution. In practice, that means fewer rejects from crystallinity or thin spots, and power draw that stays predictable across the shift. We’ve seen units run 5,000+ hours with less than 5% output drop, which keeps the tunnel calibration intact and cuts unplanned changeovers. The shop-floor details you can’t skip Installation is straightforward, but alignment is not optional. Set gap and focus to the SFL manual values, lock it down, and document it. Expect a short warm-up settle time after startup, and make sure cabinet ventilation meets the airflow requirement—infrared heaters run hot, and airflow directly affects lamp life and thermal stability. If your line runs frequent format changes, keep spares on hand; even matched emitters age, and a planned swap beats a midnight emergency change any day.

SIPA infrared lamp 2500W SK15

On the floor, a blown bottle reject is more than just scrap. It’s resin you paid for, cycle time you lost, and a line stoppage that’s just waiting to happen. On your SIPA stretch blow molder, the heating stage is where the whole run lives or dies. When the original lamp burns out, you need a replacement that hits the same thermal targets—without forcing you to pick between downtime and a premium invoice. What matters, technically The SIPA infrared lamp 2500W SK15 is a short-wave infrared emitter built around a quartz envelope and a precise filament geometry. It’s engineered for fast response and stable output inside the heating tunnel. At 2500W, it delivers the heat flux needed to bring the preform wall temperature up quickly, so the stretch blow cycle can keep pace without scorching the outer surface. The SK15 footprint and the R7s connector interface match the OEM mounting and wiring, so the lamp drops straight into the existing holders—no bracketing, no re-engineering the heating zone. Why it works on a SIPA line On SIPA blow molding lines, preform heating has to be repeatable, shift after shift. If the lamp underperforms, heating goes uneven—some preforms run hot, some run cool—and you end up chasing quality by slowing the machine down. This lamp brings you back to the original heating profile: consistent temperature across the tunnel, faster recovery after door openings, and fewer rejects from inconsistent stretch. You keep the same cycle rates and the same output, but you do it with a replacement that costs far less than the genuine part. Here’s what to watch for Installation is straightforward, but alignment is everything. Set the lamp position and reflector geometry exactly as the machine specifies; even a small offset moves the hot spot and can shift bottle thickness distribution. Also, double-check your power supply and cooling airflow. The 2500W load needs stable voltage and adequate cooling—restricted airflow will shorten lamp life. Plan replacements during scheduled maintenance and keep spares on hand so you don’t get stuck waiting.
