UNSPSC 23201000: Gas liquid contacting systems

UNSPSC 23201000 Gas liquid contacting systems is a Class code that state and local governments are actively procuring for oxygen cascade system replacement, medical gas inspection and certification, and natural gas main installation and relocation work. Recent solicitations show a mix of emergency medical services, municipal utilities, county health facilities, and educational institutions buying under this code. The scope spans removal and installation of oxygen delivery systems at EMS stations, EPA-certified refrigerant extraction and reclamation services, natural gas main boring and installation under roadways, and preventative maintenance and minor repair of medical gas systems with ASSE 6000 certification. Collier County Emergency Medical Services issued a Quick Quote solicitation (QQ2026157) in October 2026 seeking removal of three existing oxygen cascade systems and installation of four new systems at county EMS stations, with responses due October 15, 2026. The County of Santa Clara Procurement Department issued an Invitation to Bid (ITB-PRC-FY26-0636) in September 2026 for medical gas inspection, certification, preventative maintenance, and minor repair as a public work requiring prevailing wages and NFPA 99 certification, with bids due October 7, 2026.

Recent activity concentrates in Florida and California. The City of Leesburg, Florida issued an Invitation for Bid (IFB26002HG) in September 2026 for U.S. Highway 27 utility gas turnpike relocation requiring API 1104 certification and installation of approximately 1,500 feet of 6-inch steel natural gas main, with bids due November 5, 2025; the City of Tucson Environmental and General Services Division issued an RFP (240011) in September 2026 for gas extraction and removal services at the Los Reales Sustainability Campus, seeking EPA-certified refrigerant reclamers to extract gases from approximately 50 units per week with proposals due September 19, 2024. The Washington State Department of Transportation issued RFP20260825 in August 2026 for occupational medical surveillance services on behalf of Washington State Ferries, but this opportunity appears misaligned with gas liquid contacting systems scope. The geographic reach spans the Southwest (Arizona), Pacific Northwest (Washington), Southeast (Florida), and California, with no standout repeat buyers evident in the recent record.
