Introduction

Regular maintenance of industrial cooling towers is essential for ensuring optimal performance, extending equipment lifespan, and reducing energy costs. This comprehensive checklist covers all aspects of FRP cooling tower care for 2026.

Daily Maintenance Checklist

• Check water level in the basin and adjust make-up water valve as needed
• Inspect basin water temperature and compare with design specifications
• Verify fan motor current draw is within normal range
• Listen for unusual vibrations or noises from the fan assembly
• Check drift eliminator performance for excessive water carryover
• Inspect basin screens and strainers for debris accumulation
• Verify chemical treatment levels if applicable

Weekly Maintenance Tasks

• Clean basin and remove any accumulated debris or algae
• Inspect fill media for scaling, corrosion, or biological growth
• Check fan belt tension and alignment; adjust or replace as needed
• Lubricate fan motor bearings if specified by manufacturer
• Inspect couplings and gearbox for leaks and proper oil level
• Check water distribution system for even flow across fills
• Test basin water quality

Monthly Inspection Points

• Complete visual inspection of entire tower structure
• Inspect FRP panels for cracks, delamination, or UV damage
• Check all bolts and fasteners for tightness
• Inspect and clean spray nozzles or drift eliminators
• Check motor insulation resistance
• Verify vibration levels are within acceptable limits
• Inspect water treatment system components

Quarterly Maintenance

• Comprehensive cleaning of fill media with appropriate chemicals
• Inspect and clean basin float system
• Check and calibrate water level controls
• Inspect fan hub and blade condition; check blade pitch
• Verify operation of makeup water float valve
• Check structural supports and anchor bolts
• Test emergency shutdown systems

Annual Service Requirements

• Complete system flush and disinfection
• Replace fill media sections damaged beyond repair
• Full gearbox inspection and oil change
• Motor winding testing and bearing replacement
• Structural integrity assessment of FRP components
• Water treatment system optimization review
• Performance testing against original design specifications

Seasonal Preparation

Spring Start-Up Checklist

• Inspect tower for winter damage before restart
• Clean basin and remove antifreeze if used
• Check and tighten all electrical connections
• Verify all safety interlocks are functional
• Test fans at full speed before returning to service

Winter Shutdown Procedure

• Drain basin completely or maintain minimum water flow
• Apply protective coatings to exposed FRP surfaces
• Cover fan opening to prevent debris entry
• Lubricate all moving parts
• Store removable components indoors

Troubleshooting Common Issues

Safety Considerations

• Always lock out tag out electrical equipment before maintenance
• Use appropriate PPE including gloves, safety glasses
• Never work on tower during high wind conditions
• Ensure proper ventilation when working in basin areas
• Follow confined space entry procedures
• Keep area clear of slip and trip hazards
