Calgaz LtdCalgaz began as a Cambridge, Maryland, company in 1976 and became an Air Liquide-owned business after pioneering the calibration-gas market. Its development of the four-gas “Quad” mixture in 1991 helped simplify instrument testing, and the company now supports safety-critical users worldwide through three manufacturing sites. Calgaz’s quality system includes ISO 9001, ISO/IEC 17025, and ISO 17034 accreditations.CAMBRIDGE, MD
EFC Gases & Advanced MaterialsFounded in 2003, EFC Gases & Advanced Materials supplies and purifies high-purity electronic and specialty gases for advanced-technology manufacturing. Its more than 100,000-square-foot operation is especially distinctive for its Rare Gas Center of Excellence, which purifies xenon and krypton mixtures and recovers gases such as neon for reuse. EFC supports demanding semiconductor, aerospace, lighting, and window applications with in-house analytical capabilities and global shipping.HATFIELD, PA
MEECO, IncFounded in 1948 by Harvard-trained physicist Dr. Gustav Bergson, MEECO manufactures trace-moisture gas analyzers from its headquarters and plant in Warrington, Pennsylvania. Its instruments serve demanding gas-monitoring work in fields ranging from semiconductor manufacturing to industrial, natural and ultra-high-purity gases, with products including portable analyzers and process transmitters. MEECO also supports customers through an international sales and service network.334513WARRINGTON, PA
Applied Energy Systems, IncSince 1968, Applied Energy Systems has been known for solving demanding gas-delivery challenges from its Malvern, Pennsylvania operation. The company designs and builds high- and ultra-high-purity systems for customers whose production processes, especially in semiconductor manufacturing, leave little room for contamination or inconsistency. Its 32,000-plus-square-foot campus supports custom engineering and testing under one roof.333242MALVERN, PA
