§ Industry · 10

Pulp & paper: continuous lines, twenty-year machines.

Paper machines are continuous-process trains where reliability is measured in days between sheet breaks and weeks between section outages. Droz applies vibration analysis, thermography, and ultrasound to the press, dryer, and recovery-boiler sections that keep the mill running. Reference client: Smurfit.

§ Operating context

Why downtime is brutal here.

Paper mills run continuously and lose money on every sheet break and every unplanned trip.

  • Continuous web. Sheet breaks cascade into reel-quality issues and re-pulping that propagates downstream.
  • Recovery-boiler criticality. A recovery-boiler trip parks the entire mill until restart.
  • Long machine life. Twenty-year-old machines carry inherited drive-train issues that benefit from trended analysis.
  • Energy intensity. Drying, refining, and recovery are large energy consumers; condition-driven optimization pays back quickly.
