SOCIEDADE PORTUGUESA DO AR LÍQUIDO ARLÍQUIDO, LDA

SOCIEDADE PORTUGUESA DO AR LIQUIDO ARLIQUIDO, LDA specializes in the manufacture and supply of high-purity industrial gases, with a focused expertise in aviator’s breathing oxygen systems for defense applications. The contractor delivers critical life-support gases engineered to meet stringent military aviation standards, ensuring oxygen purity, pressure integrity, and contamination control for flight-critical operations. Their technical capabilities encompass cryogenic gas processing, gas purification, high-pressure storage, and packaging systems compliant with aerospace and defense specifications, particularly for portable and aircraft-integrated breathing apparatuses. The precision required for aviator’s oxygen systems—where even trace impurities can compromise pilot safety—demonstrates a high degree of process control and quality assurance in gas production and certification. The company maintains a consistent relationship with the Department of Defense, supplying mission-critical breathing gases for aviation platforms. Their work supports operational readiness across air force and naval aviation units, providing reliable, just-in-time delivery of oxygen systems that meet MIL-SPEC and NATO standards. This sustained engagement suggests deep integration into defense logistics chains and a proven ability to meet stringent military procurement timelines and performance requirements. The primary NAICS classification of 325120 reflects a niche specialization in industrial gas manufacturing, specifically tailored to aerospace and defense environments rather than general industrial or medical markets. This positions the contractor as a specialized supplier within the defense industrial base, serving a highly regulated segment requiring certified gas purity, traceability, and ruggedized packaging. The entity is structured as ZZ with no government certifications listed and is located in Alges, Portugal. While its geographic base is outside the United States, its consistent award history with U.S. defense agencies indicates an established international supply capability compliant with U.S. defense procurement regulations and export controls.
