What Coilmaster does

Coilmaster Corporation is a U.S. manufacturer of custom heat transfer solutions founded in 1999 and headquartered in Moscow, Tennessee. The company designs and produces engineered-to-order heat exchangers (condenser, evaporator, fluid, and steam coils), refrigerated case coils for food retail, fluid coolers, remote air-cooled condensers, and Coolant Distribution Units (CDUs) for data center liquid cooling. Through its 2025 acquisition of Heat Pipe Technology (HPT), Coilmaster added dehumidification and energy recovery product lines (DHP, HRM, HRM-P, HRM-V passive heat pipes). The company sells to OEM and aftermarket customers across data centers, supermarkets and food retail, commercial HVAC, automotive manufacturing, pharmaceutical and health research facilities, and industrial process cooling, with named logos including AWS, Meta, Google, xAI, Ford, GM, Toyota, Walmart, Kroger, Publix, GSK, Wyeth, CDC, Emaar, and Kellogg's.

Coilmaster's technical platform rests on proprietary technologies including Oval Tube Technology for reduced air-side pressure drop, EzCoil selection software that generates performance and pricing output for any operating system, and the VirtuaLab simulation suite that supports tube-by-tube heat exchanger modeling and vapor compression system simulation across multiple refrigerants and fluids. The 330,000 sq ft primary manufacturing facility is complemented by an on-site 20-ton psychometric test chamber commissioned in 2010, enabling in-house validation of airflow, temperature, humidity, and fluid conditions before shipment. CDUs range from 500 kW to 10 MW and integrate BACnet/IP, Modbus TCP, and SNMP for data center and building automation interoperability. The energy recovery products carry AHRI Std. 1060, ETL, UL Std. 207, and ZERO EATR certifications.

Coilmaster operates a direct enterprise field sales model supported by a nationwide network of field representatives who handle site measurements, replacement deployments, and challenging installations. Pricing is quote-based and tailored to each custom configuration, with net 30 payment terms. Revenue streams include one-time sales of custom-configured heat transfer products, professional engineering and design services, and recurring subscription licensing of the EzCoil and VertuaLab software products. The company holds multiple patents on its heat pipe technologies and Oval Tube Technology, and is owned by Marmon Holdings, Inc., a Berkshire Hathaway subsidiary that provides balance sheet and supply chain backing. Operations span three U.S. facilities in Moscow, Tennessee (headquarters), Phoenix, Arizona, and Tampa, Florida.
