The cooling tower most facility managers ignore until it fails — and why data center engineers are specifying it first.
Most cooling towers get ignored until something goes wrong. They sit on a rooftop or in a mechanical yard, they do their job, and they get serviced reactively when performance drops or something fails. That cycle of neglect works until it does not, and when a cooling tower fails in the middle of summer on a building that depends on it, the consequences are not abstract.
Tower Tech builds cooling towers specifically designed to break that cycle. FRP construction that does not rust or corrode. A modular design that can be installed in under 30 minutes and maintained without taking the system offline. A product line that spans commercial HVAC, industrial applications, and the mission-critical data center market where uptime is not a preference, it is a contractual obligation. Merion Pump Company carries Tower Tech, and the timing of this post is not coincidental. Cooling season is here and a significant wave of data center construction is underway in this region. If a cooling tower is in your future, here is what to know.
New in 2025
Tower Tech expanded its modular line in February 2025, adding closed-circuit models to its open-circuit offerings. The new TTCC-FC evaporative fluid cooler and TTCC-HC hybrid fluid cooler bring the performance advantages of FRP composite construction to closed-loop applications for the first time in the Tower Tech line. This is directly relevant to data center and industrial applications where process fluid contamination is a primary design concern.
Why FRP changes the maintenance conversation
The majority of cooling towers in commercial service are built from galvanized steel or aluminum. Both materials corrode. Corrosion is the primary reason most cooling towers fail before the end of what should be their service life. A tower that was specified for 20 years of service life ends up requiring significant repair or replacement at 12 because the basin, the structure, or the internal components have deteriorated faster than the original design anticipated.
Tower Tech builds entirely from Fiber Reinforced Polymer, a composite material that does not rust, does not corrode, and does not degrade in the wet, chemically active environment inside a cooling tower the way metal does. The internal components including fill media and, in the closed-circuit TTCC line, the heat exchanger coils themselves are composite. The result is a tower rated for a service life of over 30 years with a 15-year limited warranty to back it up. That is a materially different conversation than what most facility managers are used to having about cooling tower longevity.
“Corrosion is why most cooling towers fail before they should. Tower Tech builds the entire tower from composite materials that do not corrode. That changes the service life and maintenance conversation entirely.”
What the modular design means in practice
Tower Tech towers are factory-preassembled and delivered to site as a complete unit. Installation takes less than 30 minutes. That is not a marketing claim about a simplified process. It is a description of what happens when a cooling tower arrives on site as a finished product rather than as a collection of components that need to be assembled in the field.
The modular design also changes how maintenance works over the life of the tower. Tower Tech towers use up to twelve smaller bottom-mounted fans rather than a single large top-mounted fan. If one fan faults or needs service, the tower keeps running on the remaining fans. For applications where cooling downtime has real operational consequences, that redundancy is built into the base design rather than specified as an add-on.
The data center case is specific and strong
Data center construction is one of the most active segments in commercial construction right now. Demand for compute capacity, driven by AI infrastructure buildout and cloud expansion, is translating directly into a significant pipeline of new data center projects in this region and nationally. Every one of those facilities needs cooling, and cooling tower selection in a data center application is not a commodity decision.
The requirements are specific. Uptime must be maintained even during maintenance. Fire risk must be addressed because data centers carry significant fire load and insurance requirements that most HVAC cooling tower specifications do not need to consider. Water management is under scrutiny because large-scale data centers face regulatory and reputational pressure on water consumption. And the physical footprint matters because rooftop space and mechanical yard space on a data center site is often more constrained than it looks on the initial site plan.
Uptime during maintenance
Multiple bottom-mounted fans allow the tower to remain operational when individual fans fault or require service. No single point of failure in the fan system.
FireStrong and FM Approval
Tower Tech’s FireStrong towers are FM-approved, having undergone rigorous fire testing. A meaningful distinction in data center applications where fire safety standards and insurance requirements are non-negotiable.
Water conservation
Tower Tech’s design eliminates water loss due to windage, a source of water waste in conventional open-air inlet louver designs. Closed-circuit TTCC models use significantly less water and fewer chemicals than open-circuit alternatives.
Compact footprint
The upside-down design without side louvers eliminates the footprint penalty conventional towers carry. Towers can be placed directly adjacent to each other in virtually any configuration to maximize the use of available space.
Lightweight FRP construction
FRP is significantly lighter than steel or aluminum. Relevant for rooftop applications where structural loading is a design constraint and weight savings reduce the cost and complexity of the supporting structure.
StormStrong certification
All Tower Tech towers are StormStrong rated, certified to withstand hurricane-force winds. Relevant for coastal installations and any application where the tower is exposed to extreme weather.

If you have an aging tower or a new construction project
The conversation Merion Pump has with facility managers about cooling towers is usually one of two things. The first is a tower that is aging, showing corrosion or performance decline, and needs to be evaluated for replacement before it becomes an emergency. The second is a new construction project, often a data center, where the cooling tower specification is being developed and the engineer or owner wants to understand the full range of options before the spec is locked.
Both conversations start the same way: what does the application actually require? Capacity, footprint constraints, uptime requirements, water management goals, fire safety standards, and whether open-circuit or closed-circuit is the right configuration for the process. Tower Tech’s online sizing tool at towertechusa.com is a useful starting point. Reach out to Merion Pump and we will work through the application with you.
