UNSPSC 25174000: Engine coolant system

UNSPSC 25174000 Engine coolant system is a Class code that covers repair, maintenance, and replacement of cooling and thermal-management equipment in municipal and institutional infrastructure, based on the mix of recent state and local solicitations. The scope extends beyond automotive coolant to encompass cooling towers, chiller systems, radiators, pressure and temperature instrumentation for water and wastewater treatment plants, and related thermal components in school districts and public utilities. State and local issuing bodies pursuing this code include school districts (Hillsborough County Public Schools, Klein ISD, Parkway School District), county water and wastewater agencies (Sacramento County Water Agency, Collier County Public Utilities), municipal utilities (City of Phoenix Water Services Department), and specialized port authorities (Broward County Port Everglades). Sacramento County Water Agency and Collier County Public Utilities appear as repeat buyers, indicating sustained demand for preventative and emergency thermal-system maintenance in water management infrastructure.
