NIGP 03127: Cooling Tower Water Treatment: Non-Chemical Ozone, Centrifugal Separators, Magnetic Descaling Equip. (see Class 885 for Chemical Types)

NIGP 03127 Cooling Tower Water Treatment: Non-Chemical Ozone, Centrifugal Separators, Magnetic Descaling Equipment is an Item code representing non-chemical and mechanical water treatment systems for cooling towers and related HVAC infrastructure. State and local governments procure under this code primarily through two channels: service contracts for ongoing water treatment, testing, and maintenance at municipal facilities, water treatment plants, and school district campuses; and capital projects for cooling tower replacement, lime softening system improvements, and auxiliary equipment installation. Recent solicitations show municipalities, counties, school districts, and special-purpose authorities (convention centers, transit agencies) soliciting for full-service water treatment including chemical management, system monitoring, preventive maintenance, and emergency response across multiple facility types—chilled water loops, heating systems, condenser water loops, and cooling towers. The issuing-body mix spans city public works departments, county commissioners, independent school districts, state agencies, and regional water authorities.
