Spiral Conveyor for Mineral Water Bottling: The Bisleri Case Study

A spiral conveyor for mineral water bottling was the answer when Bisleri, India's largest mineral water bottler, needed to move packaged PET bottles through a plant built vertically across five storeys in the heart of Mumbai. Floor space was scarce, so a conventional layout with multiple transfer points was never an option. Ferag AG delivered a record-breaking ferag.skymove installation instead: two lines carry filled and packaged bottles from an upper-floor filling station down to the shipping area, 20 metres below. The descent makes this the tallest spiral conveyor Ferag has ever built, and it still reaches a throughput of up to 6,000 packaging units per hour.

Project challenge

  • Space-saving conveying across five storeys (20 m) in a “vertical” production plant
  • Transport from two production floors to three truck-loading and storage floors
  • Handling of four PET bottle shrink-pack sizes plus 5 l and 20 l individual bottles
  • Throughput of up to 100 SKUs per minute — 6,000 SKUs per hour
  • Highest reliability under continuous, heavy loads

The ferag.skymove solution

Ferag engineered a ferag.skymove plate chain conveyor configured as a compact spiral, routing bottles down through the building without a single transfer point. Because the carrier chain runs on low-friction rollers, the system copes with the weight of full PET bottle shrink-packs while keeping energy consumption and noise low — even across 20 metres of continuous vertical travel. The compact footprint let Ferag fit the entire descent into space a conventional conveyor layout could never have used.

Results

Two ferag.skymove lines now move Bisleri’s output reliably around the clock, handling up to 100 SKUs per minute across four shrink-pack formats and two individual bottle sizes. The space-saving spiral routing freed up floor area for other production steps, and the low-maintenance design keeps operating costs down — the same advantages that make ferag.skymove a fit for conveying tasks well beyond the beverage industry.
