Cylinder Fill Capacity at 99% fill station uptime: a worked example

This scenario runs the cylinder fill capacity calculation on the strong side: 99% fill station uptime, with every other input held at its documented default. Use it when planning clean agent, CO2, dry chemical, nitrogen, or stored-pressure cylinder filling capacity.

The inputs for this scenario

  • Cylinders filled per cycle: 8 cylinders / cycle (unchanged)
  • Available fill cycles: 42 cycles (unchanged)
  • Fill station uptime: 99 % (raised for this scenario; the documented default is 88)
  • Accepted fill yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross cylinder fill capacity = cylinders filled per cycle × available fill cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 323 units for good output capacity, the number this scenario is built around.
  • At this operating point the engine returns 336 units for gross capacity before uptime and yield.
  • At this operating point the engine returns 3.36 units for availability loss.
  • At this operating point the engine returns 9.98 units for reject or rework allowance.

How this compares with the baseline

  • Against the tool's baseline example, where fill station uptime sits at 88% and the headline result is 287 units, this scenario comes in 12.5% above the baseline at 323 units.
  • Use it when committing fill-line ship dates, sizing a shift to a backlog, or quantifying how much capacity downtime and rejects are quietly costing you. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Good output capacity: 323 units (headline result)
  • Gross capacity before uptime and yield: 336 units
  • Availability loss: 3.36 units
  • Reject or rework allowance: 9.98 units
