NIGP 49344: Gas Generating and Purifying Equipment: Hydrogen, Oxygen, Ozone, Pure Air, etc.

NIGP 49344 Gas Generating and Purifying Equipment: Hydrogen, Oxygen, Ozone, Pure Air, Etc. is an Item code under which state and local governments procure gas extraction services, bulk industrial gas supply and delivery, atmospheric monitoring equipment for hazardous-gas detection, and related technical support. The work involves EPA-certified refrigerant recovery and reclamation, commercial liquid oxygen supply with equipment maintenance, and fixed-installation gas sensors for water and wastewater facilities. Issuing bodies span municipal environmental and general services divisions, water treatment and wastewater authorities, and state regulatory agencies. The City of Tucson Environmental and General Services Division and City of Phoenix Water Services Department are repeat buyers under this code, each pursuing specialized gas management and detection capabilities within their own infrastructure.

Recent activity concentrates in Arizona and Florida. The City of Tucson issued RFP 240011 for gas extraction and removal services at the Los Reales Sustainability Campus, seeking an EPA-certified refrigerant reclaimer to extract gases from approximately 50 units weekly on a two-week minimum cycle, with a one-year initial term and up to four one-year renewals; proposals were due September 19, 2024. The City of Sanford, Florida Finance Department Purchasing Division issued IFB 252611 for bulk liquid oxygen delivery to its Water Treatment Plant at 3100 Orlando Drive, specifying 9,000 gallons of storage capacity and three-week delivery cycles with forty-eight-hour standard delivery and eight-hour emergency delivery capability; sealed bids were due April 9, 2026. The City of Phoenix Water Services Department issued IFB 270435 for atmospheric monitoring instruments-fixed installations to detect hydrogen sulfide, methane, oxygen depletion, chlorine, ammonia, ozone, chlorine dioxide, and carbon monoxide at lift stations, headworks buildings, and confined spaces; offers were due September 4, 2026, under a five-year non-renewable term with DBE-N participation requirements and a non-mandatory pre-offer conference on August 25, 2026.
