If you are searching for cooling tower manufacturers in USA, you will quickly discover that there is no shortage of companies to investigate.
But here is the tricky part: not every company that appears in a cooling tower search is a manufacturer. Some are distributors. Some are engineering firms. Others specialize in maintenance, replacement parts, or specific components.
So, how do you narrow the field?
This guide compares five established names that serve the U.S. cooling tower market: SPX Cooling Tech, Baltimore Aircoil Company (BAC), EVAPCO, Delta Cooling Towers, and Tower Tech.
The list is an editorial comparison rather than an official market-share ranking. The goal is to help buyers understand what each manufacturer is known for, what types of applications they serve, and what questions to ask before purchasing.
Current industry sources also show how broad the U.S. market is. Thomas currently lists more than 1,000 cooling-tower manufacturers and suppliers across the U.S. and Canada, while industry market reports identify SPX, BAC, EVAPCO, Delta, and other established companies among the major cooling-tower players.
Choosing a cooling tower is not like buying a standard piece of hardware from a catalog.
The same nominal cooling capacity can be achieved with very different equipment designs, materials, fan systems, water distribution systems, and maintenance strategies.
A cooling tower is more like the heart of a heat-rejection system. If it is undersized, poorly selected, difficult to maintain, or badly matched to the operating conditions, the problems can spread throughout the facility.
The right manufacturer should therefore be evaluated according to more than price.
Consider:
Thermal performance
Cooling capacity
Water flow
Fan power
Tower configuration
Materials
Corrosion resistance
Noise
Installation requirements
Maintenance access
Spare parts
Warranty
Technical support
Total cost of ownership
There is no single official ranking that determines the “best” five cooling tower manufacturers in the United States.
Instead, this comparison focuses on manufacturers with recognizable U.S. market presence and meaningful product portfolios.
The comparison considers four main areas.
Does the manufacturer provide crossflow, counterflow, closed-circuit, modular, packaged, or industrial solutions?
Can the manufacturer design equipment around actual project conditions rather than simply selling standard models?
Does the company serve HVAC, industrial process cooling, power generation, data centers, manufacturing, or other demanding applications?
Can customers obtain technical support, replacement components, documentation, and maintenance assistance after installation?
With those criteria in mind, let's look at five major manufacturers.
SPX Cooling Tech is one of the most recognizable names in the global cooling tower industry.
The company operates cooling technology brands including Marley, Recold, and SGS Refrigeration. SPX states that its brands have supported HVAC, refrigeration, and industrial process-cooling applications since 1922.
That long history is important because SPX is not focused on only one type of cooling tower.
Its portfolio covers a broad range of heat-rejection technologies.
SPX Cooling Tech serves applications ranging from commercial HVAC to major industrial and utility projects.
Its Marley brand is particularly well known in cooling towers, while Recold and SGS provide additional cooling and heat-transfer solutions.
This makes SPX relevant to buyers looking at:
Industrial process cooling
HVAC
Power generation
Large commercial projects
Field-erected cooling towers
Factory-assembled equipment
Replacement and aftermarket components
SPX can be particularly relevant when a project requires extensive engineering experience or a large industrial-scale solution.
For a facility manager, this can be valuable when the project involves multiple cells, large heat loads, unusual site conditions, or an existing cooling tower that needs replacement.
The important question is not simply whether SPX can supply a cooling tower.
Instead, ask which SPX brand and product family best fit the application.
Compare the actual thermal selection, fan power, materials, maintenance requirements, and lifecycle cost of the proposed system.
Baltimore Aircoil Company, commonly known as BAC, is another major manufacturer serving the U.S. cooling market.
BAC offers a wide range of cooling towers, including crossflow, counterflow, industrial modular, and closed-circuit cooling solutions.
Its current product portfolio includes the Series 3000, Series 1500, PT2, Series 5000, Series V, and FXT cooling towers.
BAC's product range is particularly broad.
For example, its Series 3000 uses an induced-draft crossflow configuration and is listed with thermal capacities from 171 to 1,446 tons.
Its Series 1500 is designed around serviceability and layout flexibility, while the PT2 uses an induced-draft counterflow configuration for applications where footprint is important.
BAC also offers industrial modular equipment designed for demanding or dirty-water applications.
Its Series 5000, for example, is positioned for industrial applications where cleanability, corrosion resistance, and uptime are important considerations.
BAC can be considered for:
Commercial HVAC
Industrial process cooling
Data centers
Manufacturing
Cooling tower replacement
Space-constrained installations
Closed-loop applications
BAC also offers closed-circuit cooling towers for applications where the process fluid needs to remain within a closed loop.
BAC has a particularly broad product selection, so buyers should avoid comparing only the company name.
Compare the exact model.
Look at:
Thermal performance
Fan system
Water flow
Footprint
Materials
Maintenance access
Energy consumption
Replacement requirements
For retrofit projects, dimensions and connection locations can be just as important as nominal cooling capacity.
EVAPCO is another major manufacturer with a strong presence in evaporative cooling and heat-transfer equipment.
The company describes itself as a manufacturing company serving evaporative cooling and industrial refrigeration markets globally. Its stated markets include commercial HVAC, industrial process cooling, data centers, industrial refrigeration, and power generation.
EVAPCO offers multiple cooling tower configurations.
Its AT cooling tower, for example, uses induced-draft counterflow technology and is available in a wide range of capacities. EVAPCO lists the AT series from 33 to 5,141 nominal tons and states that the series is independently certified by the Cooling Technology Institute.
The company also offers the AXS crossflow cooling tower.
The AXS series uses induced-draft crossflow technology and is listed from 312 to 1,405 nominal tons.
For height-restricted or indoor applications, EVAPCO also offers forced-draft, low-profile designs such as the LPT series.
EVAPCO's product portfolio makes it relevant to a wide range of projects, including:
Commercial HVAC
Industrial process cooling
Data centers
Refrigeration
Power generation
Indoor cooling applications
Retrofit projects
The company's U.S. network includes its headquarters in Westminster, Maryland, as well as manufacturing and operating locations across several U.S. states.
When evaluating EVAPCO, pay attention to the specific configuration.
A counterflow tower and crossflow tower may behave differently in terms of maintenance access, footprint, airflow, and water distribution.
The best comparison is therefore model-to-model and application-to-application.
Delta Cooling Towers is a U.S.-based manufacturer with a different approach from some traditional steel cooling tower manufacturers.
One of its major differentiators is the use of engineered HDPE construction.
Delta states that its cooling towers are manufactured in the USA and emphasizes corrosion resistance, low maintenance, and long service life.
Delta's current TMX series uses a seamless molded HDPE basin design.
The company lists TMX models from 300 to 3,250 cooling tons and highlights features such as direct-drive fans, non-corroding HDPE construction, and a 20-year shell warranty.
This material strategy can be particularly interesting for applications where corrosion is a major concern.
Why?
Because corrosion can quietly eat away at a cooling tower's structure and increase maintenance requirements.
Engineered plastics can provide a different approach to the problem.
Delta can be particularly relevant for projects where buyers are concerned about:
Corrosion
Water chemistry
Maintenance
Industrial environments
Long-term shell durability
Packaged cooling systems
Noise
Its portfolio includes both industrial and HVAC cooling tower solutions.
If comparing Delta with a conventional steel tower, don't compare only purchase price.
Compare the complete lifecycle.
Consider material durability, maintenance, water chemistry, component replacement, fan energy, and expected service life.
This is a good example of why cooling tower comparison should go beyond the first quotation.

Tower Tech is another U.S. cooling tower manufacturer included in this comparison.
Current U.S. supplier directories identify Tower Tech as a manufacturer of water cooling towers for HVAC, industrial, and utility cooling applications. Thomas describes its products as factory-assembled modular systems using non-corrosive materials.
Factory-assembled modular construction can be attractive when installation time and project simplicity are important.
Instead of building a large tower entirely at the project site, modular equipment can be manufactured and assembled under controlled factory conditions before being transported to the facility.
This can simplify certain projects.
It may also make replacement or expansion easier, depending on the site.
Tower Tech can be relevant to:
HVAC
Industrial cooling
Utility cooling
Packaged cooling projects
Modular installations
Replacement applications
When considering modular cooling towers, review transportation requirements carefully.
The factory may be able to assemble more of the equipment before shipment, but the final project still depends on:
Site access
Crane requirements
Foundation
Piping
Electrical connections
Commissioning
A modular tower is not automatically the easiest option for every project.

So, how do these five manufacturers compare?
Here is a simplified buyer-oriented comparison.
| Manufacturer | Main Strength | Typical Applications | Notable Product Approach |
|---|---|---|---|
| SPX Cooling Tech | Broad industrial and global portfolio | Industrial, power, HVAC, process cooling | Marley, Recold and SGS solutions |
| BAC | Broad product range and serviceability | HVAC, industrial, data centers, replacement | Crossflow, counterflow, modular and closed-circuit |
| EVAPCO | Broad evaporative cooling portfolio | HVAC, industrial, data centers, refrigeration | Counterflow, crossflow and specialty configurations |
| Delta Cooling Towers | HDPE and corrosion-resistant construction | Industrial, HVAC, demanding environments | Engineered-plastic cooling towers |
| Tower Tech | Modular factory-assembled approach | HVAC, industrial, utility | Modular cooling tower systems |
The table should be used as a starting point, not as a substitute for a project-specific technical selection.
There is no single cooling tower manufacturer that is automatically the right choice for every application.
A data center has different requirements from a chemical plant.
A power-generation facility has different priorities from a commercial office building.
A replacement project has different constraints from a completely new installation.
That is why the correct question is not:
“Which cooling tower manufacturer is the best?”
Instead, ask:
“Which manufacturer's product and engineering approach best match this project's requirements?”
That small change in thinking can lead to a much better purchasing decision.
U.S. manufacturers can offer several advantages.
These may include:
Domestic manufacturing
Local representatives
Shorter domestic logistics
Easier communication
Local service
Familiarity with U.S. codes
Established replacement-parts networks
But international manufacturers can also be worth considering when the project allows global sourcing.
The comparison should focus on the entire package.
Look at:
Factory capability
Engineering
Product quality
Thermal performance
Price
Shipping
Documentation
Spare parts
Warranty
Technical support
Geography is important, but it is only one part of supplier selection.
For buyers willing to consider international manufacturers, Mach Industry (Zhejiang) Co., Ltd. is another company that can be included in the comparison.
Mach Cooling is based in Zhejiang, China, and its official website presents the company as a cooling tower manufacturer serving industrial and commercial applications. Its published product portfolio includes industrial cooling towers, closed cooling towers, open cooling towers, counterflow towers, crossflow towers, and other cooling solutions.
Mach's website also publishes cooling tower content covering international manufacturers and cooling tower selection, indicating that the company is actively targeting global cooling-tower buyers.
Importantly, Mach should not be described as a U.S. manufacturer.
It is better positioned in an article like this as an international cooling tower manufacturer from China.
That distinction makes the comparison more transparent.
Depending on project requirements, Mach can be considered for different cooling tower configurations.
These include:
Industrial cooling towers
Open cooling towers
Closed cooling towers
Counterflow cooling towers
Crossflow cooling towers
Modular cooling tower solutions
For international buyers, the same questions should be asked of Mach as of any other manufacturer:
What is the thermal performance?
What materials are used?
What is the expected service life?
What documentation is available?
What is the production lead time?
What spare parts can be supplied?
How is installation supported?
These questions create a much more useful comparison than simply comparing country of origin.
International sourcing may make sense when:
The project is cost-sensitive
Custom manufacturing is required
The buyer has international procurement experience
The manufacturer has proven export experience
Technical documentation is available
Third-party inspection is possible
Spare parts can be supplied
Shipping can be managed efficiently
For large projects, buyers can also consider factory audits, third-party inspections, performance testing, and detailed contractual specifications.
The goal is simple:
Reduce uncertainty before placing the order.
Once you have a shortlist, use a structured evaluation.
Ask every manufacturer to quote against the same conditions.
At minimum, compare:
Heat load
Water flow
Entering-water temperature
Leaving-water temperature
Wet-bulb temperature
Approach
Fan power
Without common design conditions, comparing quotations can be misleading.
A tower with a lower price may simply have been selected under different conditions.
Initial price is only one piece of the puzzle.
A more useful formula is:
Total Cost = Purchase + Installation + Energy + Water + Treatment + Maintenance + Spare Parts + Downtime
A cooling tower that costs slightly more upfront may have lower operating costs.
Likewise, an inexpensive tower can become expensive if replacement parts are difficult to obtain or maintenance access is poor.
Think about the next ten or twenty years, not just the next purchase order.
Ask how easily you can obtain:
Fill
Drift eliminators
Nozzles
Fans
Motors
Bearings
Gearboxes
Shafts
Belts
Pulleys
Water distribution components
Also ask how long replacement parts typically take to arrive.
A cooling tower is only useful when it can keep operating.
The lowest price does not necessarily mean the lowest lifecycle cost.
Two towers with the same nominal tonnage can have very different energy and maintenance characteristics.
Dirty or chemically aggressive water can significantly affect fill, basins, nozzles, and other components.
A tower may look perfect on paper but require expensive structural modifications at the site.
Always ask what happens five or ten years after installation.
Different manufacturers have different design philosophies.
Some focus heavily on industrial applications.
Others emphasize modular equipment, corrosion resistance, serviceability, energy efficiency, or compact footprints.
Before signing an agreement, ask:
What cooling capacity is guaranteed?
What are the design conditions?
What water flow is required?
What wet-bulb temperature is used?
What tower configuration is proposed?
What type of fill is used?
What materials are used?
What is the fan motor power?
What is the expected sound level?
What maintenance is required?
What spare parts are available?
What is the warranty?
What is the delivery time?
What installation support is included?
Can the manufacturer provide similar project references?
What technical documentation will be supplied?
The manufacturer that answers these questions clearly gives you a much better foundation for decision-making.
The U.S. cooling tower market includes many manufacturers, suppliers, distributors, and service companies, so choosing the right supplier requires more than a quick Google search.
This comparison looked at five established names:
SPX Cooling Tech, Baltimore Aircoil Company, EVAPCO, Delta Cooling Towers, and Tower Tech.
Each has a different product portfolio and design approach.
SPX offers a broad portfolio through brands such as Marley, Recold, and SGS.
BAC provides a wide range of crossflow, counterflow, modular, and closed-circuit solutions.
EVAPCO offers extensive evaporative cooling products for HVAC, industrial, data-center, refrigeration, and power applications.
Delta differentiates itself with engineered HDPE cooling tower technology and an emphasis on corrosion resistance.
Tower Tech focuses on modular factory-assembled cooling tower solutions.
For buyers willing to source internationally, Mach Industry (Zhejiang) Co., Ltd. can also be evaluated as a China-based cooling tower manufacturer.
Ultimately, there is no shortcut to selecting the right cooling tower.
Start with the operating conditions.
Then compare thermal performance, construction, energy consumption, maintenance, installation, spare parts, service, warranty, and total cost of ownership.
The best purchasing decision is rarely about finding the cheapest tower.
It is about finding a cooling tower that continues to perform reliably long after the purchase order has been forgotten.
Major manufacturers serving the U.S. market include SPX Cooling Tech, Baltimore Aircoil Company, EVAPCO, Delta Cooling Towers, and Tower Tech, among others. Industry directories also list numerous smaller manufacturers, custom manufacturers, distributors, and service companies.
SPX Cooling Tech is a major global cooling technology manufacturer with a significant U.S. presence. Its brands include Marley, Recold, and SGS Refrigeration, serving HVAC, refrigeration, and industrial process cooling applications.
Baltimore Aircoil Company offers a broad range of cooling towers, including crossflow, counterflow, industrial modular, and closed-circuit cooling products. Its current portfolio includes the Series 3000, Series 1500, PT2, Series 5000, Series V, and FXT cooling towers.
EVAPCO manufactures several cooling tower configurations, including induced-draft counterflow and crossflow towers as well as forced-draft products. Its products serve commercial HVAC, industrial process cooling, data centers, refrigeration, and other applications.
Delta emphasizes engineered HDPE cooling tower construction. Its current TMX series uses a molded HDPE basin and is marketed for corrosion resistance, low maintenance, and long service life.
No. Mach Industry (Zhejiang) Co., Ltd. is based in Zhejiang, China. It should therefore be described as an international or Chinese cooling tower manufacturer rather than a U.S. manufacturer. Its official website presents a range of industrial, open, closed, counterflow, and crossflow cooling tower products.
Not necessarily. If project requirements permit international sourcing, overseas manufacturers can also be evaluated. Buyers should compare engineering capability, quality, thermal performance, documentation, delivery, warranty, spare parts, and after-sales support.
Use the same operating conditions for every quotation. Compare thermal capacity, water flow, temperatures, wet-bulb conditions, fan power, materials, dimensions, maintenance, warranty, spare parts, delivery, and total lifecycle cost.
