SELECT GASES, LLC

SELECT GASES, LLC specializes in the manufacturing and delivery of high-purity industrial gases and cryogenic systems for mission-critical federal applications. The company provides hydrogen propellants, liquid argon, nitrogen, and dry ice under stringent quality controls, serving defense and biomedical environments where gas purity, thermal stability, and just-in-time logistics are essential. Their technical expertise includes cryogenic storage and transport infrastructure, gas handling systems compliant with DOT and OSHA standards, and tailored delivery solutions for sensitive applications such as rocket propulsion, laboratory freezing, and sample preservation. A key differentiator is their ability to integrate gas supply with specialized equipment like LN2 freezers, demonstrating cross-domain competency in both gas production and refrigeration system support. The contractor maintains a strong, recurring relationship with the Department of Defense, supplying hydrogen-based propellants for aerospace and ordnance systems, and the Department of Health and Human Services, where they support FDA and biomedical research operations through bulk gas delivery and cryogenic freezer logistics. Their work for HHS often involves maintaining ultra-low temperature chains for biological samples, indicating deep familiarity with biospecimen integrity requirements. Primarily operating under NAICS 325120, SELECT GASES, LLC focuses on industrial gas manufacturing with secondary capabilities in commercial refrigeration equipment (NAICS 333415) and analytical instrumentation support (NAICS 334516). This positions them as a niche supplier bridging gas chemistry with laboratory and defense hardware ecosystems, particularly where gas purity and thermal management intersect. Based in Norcross, Georgia, the company operates as a small business under the 2L entity structure. While no formal government certifications are listed, their consistent delivery of mission-critical gases to DoD and HHS underscores proven reliability in regulated federal supply chains. Their geographic footprint supports rapid response across the southeastern U.S. with scalable logistics for time-sensitive federal requirements.
