Industrial Cooling Tower Refurbishment & Basin Coating

Specification: BAC, Marley & Evapco Specialists • 10-Yr Basin Waterproofing

Baltimore Aircoil (BAC), Marley & Evapco cooling tower overhauls. Multi-layer epoxy basin relining, gear drive laser alignment, and fill pack replacement.

Engineering Scope & Overview

Cooling towers are the thermal heat-rejection heart of every water-cooled central plant. Constant exposure to hard high-calcium water, atmospheric dirt, and chemical biocides causes severe galvanization corrosion, basin leaks, scale-fouled fill packs, and mechanical gearbox failures. Replacing a multi-cell cooling tower costs hundreds of thousands of dollars and weeks of crane downtime. Western Mechanical Inc. restores aging cooling towers to like-new thermal efficiency at a fraction of the replacement cost. We perform turnkey basin sandblasting and thick-film elastomeric epoxy recoating, crossflow and counterflow PVC fill pack replacement, high-efficiency drift eliminator upgrades, and precision drive shaft laser alignment.

WMI Field Protocol & Certified Best Practices

• Abrasive blast cleaning and high-build epoxy elastomeric basin restoration (10-year leak protection)
• Precision laser alignment of fan shafts, motor pulleys, and right-angle gear reducers
• Thermal-upgrade PVC film fill and biological drift eliminator replacement
• Dynamic vibration testing of fan assemblies to prevent blade catastrophic structural failure

Frequently Asked Questions

Can a corroded, leaking cooling tower cold water basin be repaired without replacing the tower?

Yes. We drain, power-wash, abrasive blast to white metal, and apply an engineered multi-layer thick-film polyurethane or epoxy lining that seals all rusted seams and provides a durable 10-year waterproof seal.

How does replacing fouled tower fill improve chiller plant energy efficiency?

Fouled or scaled fill packs restrict air-to-water heat transfer, elevating condenser water return temperatures by 3°F to 8°F. For every 1°F drop in condenser water temperature, central chiller compressor energy drops by 1.5% to 2%.

What causes cooling tower fan vibration and how do you resolve it?

Vibration typically stems from failed bearing sleeves, misaligned drive shafts, or imbalanced composite fan blades. Our certified technicians perform dynamic in-place fan balancing and two-plane laser shaft alignment.
