Producer
Chart Industries, Inc. (BAHX Division)
American industrial equipment company (NYSE: GTLS, HQ Ball Ground GA; ~$3.5B revenue post-Howden acquisition); Chart Industries is the largest independent (non-captive) producer of brazed aluminum heat exchangers (BAHX) for cryogenic air separation and LNG liquefaction. Chart's Clarksburg West Virginia and La Crosse Wisconsin facilities manufacture BAHX using vacuum brazing furnaces — a process where aluminum fins and parting sheets are assembled and heated to 580-620°C in a vacuum, causing a brazing alloy to flow and permanently bond thousands of aluminum surfaces. Chart is the primary BAHX supplier to Air Products, Air Liquide, and Messer for their cryogenic ASU builds. The Chart Clarksburg WV facility is one of only a handful of facilities in the world capable of vacuum-brazing heat exchangers of the size required for large ASUs — units that can stand 3-4 meters tall and weigh 15-20 tonnes. BAHX lead times (18-24 months) mean that a decision to expand industrial gas production must be made nearly 2 years before the heat exchanger arrives.

Did you know2023
Chart Industries BAHX are used in industrial gas air separation units (which produce oxygen for hospital systems and semiconductor fab inert environments, nitrogen for semiconductor fab cooling, neon for chip lithography lasers) AND in LNG liquefaction plants (for US natural gas export to Europe and Asia). The same vacuum-brazed aluminum heat exchanger from Chart's West Virginia facility enables industrial gas supply for semiconductors and healthcare simultaneously with LNG export for global energy trade. An 18-24 month BAHX lead time means that BAHX capacity decisions made today will constrain industrial gas and LNG production capacity 2 years into the future -- creating a long-horizon chokepoint. A Chart facility fire or vacuum brazing furnace failure at Clarksburg, WV would simultaneously delay industrial gas ASU expansion projects (affecting hospital oxygen and semiconductor gas supply timelines) and LNG liquefaction projects (affecting energy export capacity decisions) -- with no available substitutes at comparable BAHX size within the same lead time.
Chart Industries, Inc. ↗Origin2023
Chart Industries was founded in 1992 as a spin-off from the Cleveland-based Ohio Art Company (the Etch A Sketch company) -- an unexpected origin for an industrial cryogenic equipment manufacturer. Chart's founding business was cryogenic pressure vessels and heat exchangers, which it grew through acquisitions to become the leading independent BAHX manufacturer globally. The Howden acquisition ($4.4B, March 2023) was transformational: it combined Chart's heat exchanger and cryogenic equipment capabilities with Howden's compressor and fan technology, creating a company that can supply both the thermal exchange equipment AND the rotating machinery for cryogenic air separation and LNG liquefaction. Before the Howden acquisition, Chart's customers (Air Products, Air Liquide, Linde) bought BAHX from Chart and compressors from separate suppliers; after the acquisition, Chart can supply integrated cold box + compressor packages. The acquisition repositioned Chart from a component supplier to a system integrator -- potentially competing more directly with its own major customers who are themselves integrated ASU builders.
