American Exchanger Services

What American Exchanger Services does

American Exchanger Services, Inc. (AmX) is a privately held, family-owned designer and manufacturer of custom heat transfer equipment for the power generation, nuclear, pulp and paper, process, and renewable energy industries. Founded in 1984 by Thomas J. Muldoon, PE in Hartford, Wisconsin, the company operates two fabrication facilities (a headquarters plant on W Wisconsin St and a dedicated machining center on Innovation Way) and produces feedwater heaters (high pressure horizontal, high pressure vertical head-down, low pressure horizontal, and condenser neck configurations), main steam condensers rated from 1MW to 600MW, balance-of-plant shell and tube heat exchangers (including nuclear fuel pool and lockhopper coolers), and pulp and paper-specific digester steam economizers and flash coolers.

The company's technical differentiation rests on proprietary thermal design and second-law thermodynamic software developed in-house, a patented Power Recovery Condensing System for renewable power generation, a proprietary No Tube In Window feedwater heater desuperheating design, and a 1986-licensed impactor explosive welding technology from International Research and Development Co. that enables high-energy-rate fabrication for nuclear and critical-service applications. AmX is a certified ASME Code Shop holding U, R, and PP Stamps, and is a member of the Heat Exchange Institute (HEI) where it participates in writing industry standards. Engineering quality is reinforced by leadership credentials including Muldoon's ASME Fellowship (2014), Director of Sales Brent L. Jones's 43 years of heat transfer experience across SPX Heat Transfer, Alstom, and Yuba Heat Transfer, and VP Quality James Frankiewicz's authorship of the in-house thermal design software.

AmX's business model is project-based custom manufacturing complemented by turnkey field service. Revenue is generated primarily from one-time equipment sales of bespoke, customer-specification-driven fabrications, supplemented by professional services revenue from field installation, retubing, retrofits, and emergency outage support. The company maintains a direct enterprise field-sales motion targeting utilities, nuclear facilities, pulp and paper mills, and process plants, and has expanded internationally since 2013 into Indonesia, Malaysia, and South America — earning the SBA Exporter of the Year (Great Lakes Region) award in 2015. Current strategic focus areas include hydrogen production equipment, Small Modular Reactor heat exchangers, and nuclear fusion components, positioning the company at the intersection of legacy power generation and decarbonization-era process equipment.
