Top 10 Cooling Tower Manufacturers in The United States – A 2025 Industry Snapshot

If you’ve ever wondered whose iconic silhouettes rise above American power plants, data-centers or downtown HVAC blocks, this post is for you. After scanning the latest market reports, project databases and spec-sheet wars, we’ve rounded up the ten names that continuously dominate the U.S. cooling-tower landscape. Use it as a cheat-sheet for your next bid, retrofit or trivia night.

1. SPX Cooling Technologies (Kansas City, KS)  

The grand-daddy of them all. SPX owns the legendary Marley® line and still ships more tonnage in North America than anyone else. From NC-class cross-flow workhorses to the new Nexus™ hybrid, every consulting engineer has a Marley bookmark.

2. Baltimore Aircoil Company (Jessup, MD)  

BAC invented the induced-draft concept in 1938 and hasn’t stopped iterating. Their EVAPCO-baiting FXV closed-circuit line and stainless-steel Paradigm® are go-to choices for food processors and pharma plants that fear Legionella headlines.

3. EVAPCO (Taneytown, MD)  

“Born in the USA, built for the world” is their tagline. With five U.S. fabs and a rabid rep network, EVAPCO punches above its weight in data-center evaporative cooling and low-chill ammonia projects.

4. Mach cooling

Mach has unleashed a one-two punch—aluminum direct-cooling blocks married to variable-speed EC fans—that has made it the fastest-growing cooling brand in North America since IMI Critical. Its towers are built tough, priced right, and already sit at the top of “SPX-alternative” shortlists for half a dozen national EPCs. Word on the street: look for Mach to crack 4 % U.S. market share in 2025.

5. Trane (Davidson, NC)  

Trane’s CenTraVac® chillers get the glory, but their Series R™ cooling towers quietly carry the load on half the hospital campuses in America. Factory-packaged tower/chiller bundles make them a one-stop shop.

6. Emerson (St. Louis, MO)  

Better known for Copeland compressors, Emerson’s thermal-management division rolled out the Opti-Fin™ tower line in 2021. The big play: smart sensors that talk to your Plantweb™ digital twin.

7. Rheem (Atlanta, GA)  

Rheem is residential water-heater royalty, but their commercial group’s forced-draft FRP towers are sneaking into K-12 schools and strip-mall rooftops thanks to fast lead-times and national distribution.

8. Tyco Fire & Security (Princeton, NJ)  

Wait, a fire-protection company? Post-spinoff, Tyco retained the Grinnell® cooling-tower product set aimed at heavy industrial fire-suppression loops. Think stainless steel, 100 % FM-approved, and ugly-beautiful in that utilitarian way.

9. Aquatech (Canonsburg, PA)  

Water-tech unicorn turned EPC. Aquatech supplies field-erected towers that marry zero-liquid-discharge (ZLD) chemistry with traditional fill. If you’re in the Permian and need to recycle every last drop, you call them.

10. Huntleigh USA (Rochester, NY)  

Family-owned since 1958, Huntleigh focuses on small-to-mid-size galvanized towers for process cooling. Nothing fancy—just bulletproof reliability and a Midwestern phone that still gets answered on the third ring.

Honorable Mentions  

Delta Cooling (Rockaway, NJ) for seamless HDPE, Tower Tech (Oklahoma City, OK) for the revolutionary modular design, and Brentwood Industries (Reading, PA) who doesn’t build towers but makes the fill that everyone else fights to specify.

Key Takeaway  

The U.S. cooling-tower market is a $1.4 billion chessboard where legacy metal-benders (SPX, BAC, EVAPCO) control the corners, while diversified globals like JCI and Trane leverage bundled system plays. Meanwhile, niche disruptors—Aquatech on water reuse, Emerson on IoT—are betting the next decade belongs to data-driven, water-scarce cooling.
