What Cooling Tower Depot, Inc. does

Cooling Tower Depot, Inc. ("CTD") is a privately held Colorado corporation founded in 2003 and headquartered in Golden, Colorado, that manufactures and services industrial cooling towers and operates the industry's only online parts warehouse under the DEPOT™ brand. The company's product portfolio centers on field-erected DEPOT™ cooling towers ranging from 3,000 to 300,000 gpm in both counterflow (CF Series) and crossflow (XF Series) configurations, supplemented by a Double Wall CFU series, modular packaged towers, an Ethanol Series for biofuel facilities, a Plume Abated Series for arid-environment water-conservation applications, an Add Cell Series for retrofits, and rental cooling tower units. CTD also markets replacement parts compatible with Marley® field-erected towers — including M Series gearboxes, driveshafts, fans, fill, drift eliminators, nozzles, FRP structural members, valves, hardware, and accessories such as plume abatement, fire protection, lightning protection, wet down, and noise attenuation systems — alongside repair, reconstruction, emergency response, and inspection services. Its customer base spans heavy industrial facilities (power generation, petrochemical, refining, heavy manufacturing), ethanol/biofuel plants, commercial HVAC, and municipal/government water and district-cooling infrastructure, with field-erected installations claimed worldwide. Revenue is generated through a mix of one-time new-tower sales, online and direct phone parts sales, professional repair and reconstruction services, and hardware rentals, priced on per-unit and per-project bid bases (e.g., Marley M Series gearboxes $34,397–$61,743; butterfly valves $223–$1,329; FRP walkways $300/linear foot). Commercial channels are sales-led via a toll-free sales line and online quote/bid forms, with the company website and online configurator functioning as both a content-marketing funnel and a self-service parts storefront. No external investors, parent companies, subsidiaries, M&A activity, or financial disclosures (revenue, headcount detail, funding rounds) appear in the available data.
