Chart Industries (NYSE: GTLS; Ball Ground, GA; ~$4B revenue post-Howden) is the world's dominant manufacturer of cryogenic equipment for LNG, including peak-shaving plant liquefiers, brazed aluminum heat exchangers (BAHX), cold boxes, storage tanks, and LNG vaporizers. Chart's Industrial & Commercial Energy (ICE) division is the primary vendor for utility LNG peak-shaving plant equipment in North America. Chart acquired Howden (Glasgow-based industrial compressor and fan manufacturer) in 2023 for $4.4B, adding compression technology to its cryogenic heat exchanger and storage portfolio — making Chart a near-complete LNG equipment systems integrator. Chart also produces the CAIRE/MVE biomedical cryogenic cylinders and acquired La Crosse Cooler and other brands. The La Crosse, WI cryogenic division manufactures vacuum-insulated storage vessels. Chart is the single most critical equipment supplier for US utility LNG peak-shaving — if a New England utility needs to expand or replace a peak-shaving liquefier, Chart is essentially the only qualified domestic source.

Luoyang Jianlong Micro-Nano New Materials Co., Ltd. (Luoyang, Henan Province, China) is a leading Chinese manufacturer of synthetic zeolite molecular sieves including 4A, 5A, 13X NaX, and LiX grades for PSA oxygen, nitrogen, and industrial gas separation applications. Part of the Jianlong Group (privately-held diversified heavy industry conglomerate). Henan Province has become China's primary zeolite molecular sieve production cluster, with multiple manufacturers concentrated in Luoyang. Luoyang Jianlong supplies domestic Chinese oxygen concentrator manufacturers at scale — China surged zeolite production during COVID-19 to supply global oxygen concentrator demand when hospitals worldwide reported oxygen shortages. Chinese molecular sieve manufacturers now supply a growing share of global PSA zeolite, gaining position especially in Asia-Pacific and emerging markets. The concentration of Chinese LiX zeolite production in Henan Province creates a geographic chokepoint.
