About UNSPSC 25171603
UNSPSC 25171603 Train defrosting or defogging systems is a Commodity code that does not reflect the work actually being solicited under it in recent state and local opportunities. The recent opportunities tagged with this code show no procurement activity for train defrosting or defogging systems. Instead, the posted solicitations cover HVAC components, parts, and services — breathing air purifiers, condenser blower assemblies, fresh air filters, evaporator coils, heater elements, compressor isolators, and chiller maintenance — that fall outside the nominal scope of the code. The issuing bodies include state military departments, transit authorities (Dallas Area Rapid Transit Authority, Dallas County for light rail), county facilities management (Monroe County), a city airport department (City of Dallas), and independent school districts or comparable regional bodies. Dallas Area Rapid Transit Authority appears as a repeat buyer across multiple opportunities for component parts and assemblies supporting bus and light rail vehicle HVAC and pneumatic systems.
Geographic activity concentrates in Texas — Dallas-Fort Worth (DART procurements), Dallas County, Monroe County, Florida, and Oregon (Oregon Military Department). Recent representative opportunities include the Oregon Military Department's RFQ for a breathing air purifier replacement at Camp Withycombe (due July 21, 2026); Dallas Area Rapid Transit Authority's RFQ for condenser blower fan/motor assemblies, fresh air filters in multiple configurations, and HVAC evaporator coils (responses due between March and June 2026); Monroe County Board of County Commissioners' RFP for countywide chiller maintenance and service at multiple locations (due June 17, 2026); Dallas County's RFQ for rebuilt compressor assemblies for light rail vehicle fleets (due July 21, 2026); and the City of Dallas Department of Aviation's RFB for removal and installation of pre-conditioned air HVAC units at Dallas Love Field Airport (due February 20, 2026). The code's abstract definition and recent procurement activity are substantially misaligned, suggesting either a tagging error or that the code has drifted from its intended scope in state and local practice.
