Common Issues & Solutions
Gearbox oil leaks/failures
Symptoms:
Oil leakage, unusual gearbox noise, elevated oil temperature, metal particles in oil
Solution:
Check oil level and quality, inspect seals, verify proper alignment, replace worn gears or bearings, ensure proper lubrication schedule, upgrade to Marley Geareducer if applicable.
Structural deterioration
Symptoms:
Visible corrosion, wood rot, structural deflection, loose connections, water leakage
Solution:
Inspect structural components regularly, replace damaged members, apply protective coatings, verify proper water treatment to prevent accelerated deterioration, consider upgrading to more corrosion-resistant materials.
Drift eliminator damage
Symptoms:
Excessive water carryover, visible water droplets in discharge air, water loss, icing issues in winter
Solution:
Inspect and replace damaged eliminators, ensure proper installation without gaps, upgrade to more efficient designs like MarKey drift eliminators, verify air and water flow rates are within design parameters.

Frequently Asked Questions
What are the differences between Marley's crossflow and counterflow cooling towers?
In Marley's crossflow designs (like the NC series), air flows horizontally across falling water, providing easy access to internal components and drift eliminators. In counterflow designs (like the MD series), air flows vertically upward against falling water, offering a smaller footprint and potentially higher efficiency.
What materials are used in Marley cooling tower construction?
Marley offers multiple material options including galvanized steel (standard), stainless steel (304 or 316 for corrosion resistance), HDPE (high-density polyethylene for factory-assembled models), and fiberglass reinforced polyester (FRP) for specific components or complete structures in corrosive environments.
How quiet are Marley cooling towers?
Marley offers several low-sound options including Ultra Quiet fans, sound attenuation packages, Variable Frequency Drives, and specifically designed Low Sound models. Sound levels can be reduced by 10-20 dBA compared to standard models, with published sound data available for specific configurations.
What control systems are available for Marley cooling towers?
Marley offers several control options including the Marley Control Systems package with PLC controllers, basin water level controls, vibration switches, variable frequency drives with Marley Premium VFD software, Building Management System integration, and remote monitoring capabilities.
