What Dunham-Bush USA LLC does

Dunham-Bush USA LLC is the Americas operating subsidiary of Malaysian parent Dunham-Bush Holding Bhd, headquartered in Homestead, Florida. Founded in the USA in 1894 as the C.A. Dunham Company, the firm is one of the oldest global commercial HVAC manufacturers, with its global headquarters relocated to Malaysia in 1998. The company manufactures and supplies commercial and industrial HVAC systems including water-cooled and air-cooled chillers (centrifugal, screw, scroll), heat pumps, air handling units, fan coil units, VRF systems, precision control units, and patented ice thermal storage (ICE-CEL). Dunham-Bush holds proprietary positions in eighth-generation hermetic vertical screw compressors (only global producer) and is one of few manufacturers of magnetic bearing centrifugal compressors (oil-free, high efficiency).

The business operates a hardware sales model with quote-based pricing distributed through an extensive authorized sales and service agent network covering all US states, Canada, Mexico, the Caribbean, Central and South America, and Guam, supported by regional service managers and a RepNet dealer portal. Customers span commercial buildings (primary segment), industrial facilities (manufacturing plants, data centers), and residential applications including notable installations at NASA Johnson Space Center, NASA Kennedy Space Center, Iowa State University, and The Estates at Acqualina. Manufacturing is conducted in Yantai (China, 1995), Kajang (Malaysia, 1998), Havant (UK), with a new Miami factory (2019) localizing Americas production.

Recent strategic activity emphasizes higher-efficiency and low-GWP-refrigerant product lines (Athena ACM-AE, ACHX-D Helios with HFO-R513A), connected equipment via the DB-C2C IoT monitoring platform, and product launches spanning 2 RT precision units to 3,000 RT centrifugal chillers. The company is privately held with no public financials, 501–1,000 employees, and operates as a foreign-parent multinational with the US entity serving as the Americas regional hub under CEO Zhou Lei of the parent group.
