Kanchanaburi: 12-Cell Cooling Tower Performance and Airflow Assessment
Synergy Services carried out a performance and airflow assessment covering 12 cooling-tower cells for the Kanchanaburi site at Bo Phloi, Kanchanaburi. The programme combined thermal measurements, fan airflow traverses and cell-level engineering reports to establish a baseline for maintenance and upgrade decisions.
One three-cell crossflow tower, U-911, illustrates the assessment. Because the original manufacturer performance curve was unavailable, the team generated a reference curve from available design data and separated the measured/Toolkit result from the subsequent engineering estimate.
Project at a glance
| Item | Project record |
|---|---|
| Customer | Site identity withheld |
| Scope | Performance and airflow testing across 12 cells |
| Example unit | U-911, three-cell induced-draft crossflow cooling tower |
| Thermal method | Project scope referenced CTI Acceptance Test Code ATC-105 |
| Test date shown in U-911 report | 9 June 2026 |
| Generated curve Model Result Level | 66.4% |
| CTI Toolkit capability versus generated curve | 73.6% |
| Engineering estimate versus original-design basis | 48.9% |
U-911 evaluation
The generated curve produced an MRL of 66.4%. The field test evaluated against that generated curve produced a 73.6% tower-capability result in CTI Toolkit. The report then multiplied the two factors to estimate performance relative to the original design basis:
66.4% × 73.6% = 48.9% estimated original-design capability.
That 48.9% value is explicitly an engineering estimate. It should not be described as CTI certification or as a direct Toolkit result against the missing original manufacturer curve.
Recorded test condition
| Parameter | Test result |
|---|---|
| Hot-water temperature | 32.86°C |
| Cold-water temperature | 30.84°C |
| Cooling range | 2.02°C |
| Entering wet-bulb temperature | 27.32°C |
| Total measured fan power | 41.07 kW |
Cell-level airflow
| U-911 cell | Airflow | Fan power |
|---|---|---|
| A | 23.00 m³/s | 14.48 kW |
| B | 22.35 m³/s | 12.90 kW |
| C | 21.65 m³/s | 13.69 kW |
The value of the assessment is the repeatable baseline: plant teams can compare future thermal, airflow and fan-power measurements against the same cells instead of relying on a single temperature reading.
