Cooling tower remains in operational mode throughout the year, especially in regions temperature remains between 30 degree Celsius - 50 degree Celsius. Sometime, despite of taking good care the tower may not give satisfactory performance. In such case, user may consider the following points:- Optimize cooling tower fan blade angle as per season.
- Correct the uneven blade tip and poor fan balance
- Replace some cooling tower parts like splash bars with PVC cellular film fill, spray type nozzles with new square type nozzle.
- Opt for nozzle that do not clog
- Cover water basin to minimize biological growth
- Maintain static water distribution system
- Keep the cooling water temperature to minimum level
- Monitor approach, effectiveness and cooling capacity
- Monitor liquid to gas ratio and water flow rates
- Keep an eye on cooling water pumps regularly
- Consider energy efficient FRP towers and blades for fan energy saving
- Opt for multi-cell cooling towers i.e number of fans and motors per cell
- Consider nozzles and sprays made of stainless steel to avoid corrosion problem.
