Cooling Tower Restoration
Extend cooling tower life, restore thermal capacity, and eliminate fouling for safer, more efficient operation.
Thermal Capacity & Safety
Cooling towers degrade through scale, biological fouling, and corrosion. We restore the heat rejection capacity your chiller plant depends on.
Biological Fouling
Legionella and biofilm growth in warm, recirculated water pose serious health risks.
Scale Buildup
Mineral deposits on fill media and basin surfaces reduce heat transfer efficiency.
Basin Corrosion
Leaking basins waste water, chemicals, and compromise structural integrity.
Mechanical Wear
Fan assemblies, drift eliminators, and nozzles degrade over time without intervention.
Tower Restoration Protocol
A full-scope cooling tower restoration addresses biological, mechanical, and structural deficiencies in a single mobilization.
Decontamination & Cleaning
Removing sludge, biofilm, and debris from the basin, fill, and distribution system.
- Basin vacuuming
- Fill pressure washing
- Nozzle clearing
Mechanical Inspection
Evaluating fan assemblies, drift eliminators, and structural components.
- Fan balance check
- Belt/Drive inspection
- Drift eliminator assessment
Surface Restoration
Repairing and coating basins, sumps, and structural steel.
- Epoxy lining
- Seam repair
- Steel re-coating
Return to Service
Filling, treating, and documenting the restored system.

Efficiency Recovery
Measurable Performance Recovery
A comprehensive cooling tower restoration costs a fraction of replacement while recovering thermal capacity and extending asset life by 5-10 years.
Frequently Asked Questions
How long does a commercial cooling tower restoration take?
Most single-cell restorations complete in 5–10 working days depending on scope. BAM phases work to maintain partial cooling capacity so your facility never goes fully offline. We coordinate mobilization around your peak load schedule and water treatment cycles to minimize operational disruption.
Can cooling tower restoration be performed while the building is occupied?
Yes. BAM engineers phased containment plans that isolate the work cell while adjacent cells continue operating. This is standard practice for hospitals and manufacturing plants where cooling interruption risks patient safety or production losses exceeding $50,000 per day.
Does cooling tower cleaning reduce Legionella risk?
It is one of the most effective interventions. Removing biofilm and sediment eliminates the harborage sites where Legionella pneumophila colonizes. BAM's decontamination protocol aligns with ASHRAE Standard 188 and coordinates with your water treatment vendor to maintain biocide efficacy throughout the restoration.
What is the cost of cooling tower restoration versus full replacement?
Restoration typically costs 15–25% of full tower replacement while extending asset life by 5–10 years. It eliminates the crane mobilization, structural engineering, and extended downtime a replacement demands. BAM's scope addresses basin corrosion, fill degradation, and mechanical wear in a single mobilization.
How does cooling tower fouling affect chiller plant energy consumption?
Fouled fill and scaled basins raise condenser water temperature, forcing chillers to operate at higher head pressure. This can increase compressor energy consumption by 15–30%. BAM's restoration recovers thermal rejection capacity to near-design conditions, directly reducing kW/ton across your chiller plant.
What certifications should a cooling tower restoration contractor hold?
At minimum, OSHA-30, confined space entry, and fall protection certifications. BAM technicians hold all three plus Universal EPA certification. We follow ASHRAE 188 for Legionella risk management and CTI guidelines for thermal performance, ensuring every restoration meets institutional compliance standards.
