Precision Shaft Alignment for Cooling Towers

on install and after any disturbance is the baseline. Adjust based on duty cycle: assets running near rated capacity 24/7 get tighter intervals; intermittent-duty units can stretch the interval by 50%. The general rule for Cooling Tower Reliability & Maintenance specifically is that PdM cadence should be no more than half the dominant failure mode's P-F interval. For most Cooling Tower Reliability & Maintenance populations that lands at monthly walking, quarterly mechanical.

The Cooling Tower Reliability & Maintenance failure population is dominated by fan gearbox wear, fill degradation, structural corrosion. Each leaves a different signature: rising approach, fan vibration, fill collapse. Precision Shaft Alignment captures these via angular and offset misalignment to OEM spec and trends them over the on install and after any disturbance schedule. Early-stage indicators appear before functional failure — the lead time runs immediate (event-driven) on most modes.

Value rises with age. New Cooling Towers rarely show developing faults during the first 1,000 to 3,000 operating hours. The middle of the asset life (years 2-7 typically) is where Precision Shaft Alignment catches the most actionable findings. Late-life equipment — past the 15 to 25 years mark — shows higher fault frequency and benefits from tighter monitoring intervals than the program baseline.
