UNSPSC 40101836: Shell and tube heat exchanger

UNSPSC 40101836 Shell and tube heat exchanger is a Commodity code purchasing chiller replacement, chiller plant upgrades, chiller maintenance and repair services, and condenser coil procurement across state and local facilities. The recent opportunities show state and local jurisdictions are primarily acquiring complete chiller replacement installations, plant-wide mechanical system upgrades combining chillers with pumps, hydronic accessories, control systems and piping, as-needed chiller maintenance and repair contracts, and component replacement such as condenser coils and variable frequency drives. Water-cooled centrifugal and screw chillers dominate the specified equipment, along with air-cooled scroll chillers for specialized applications. Issuing bodies span county governments, city municipalities, state university systems, school districts, state agencies, and special-purpose authorities. County commissioners' courts in Texas (Williamson County) and Florida (Orange County, Monroe County, Volusia County, Glynn County), municipal governments in Florida (St. Petersburg, College Park), and state agencies (Oregon Department of Transportation, Oregon Military Department, Texas Health and Human Services Commission) appear repeatedly. School districts in Florida (Pinellas County, Marion County) and a community college in Mississippi (Pearl River) also solicit under this code.

Activity concentrates in Florida, Texas, Georgia, and Oregon, with scattered opportunities in Mississippi, California, and Washington state. Representative recent solicitations include Texas Health and Human Services Commission's July 2026 IFB for preventative maintenance and diagnostic service of HVAC and refrigeration equipment at Rio Grande State Center (response due July 31, 2026); City of St. Petersburg's July 2026 RFQ for chiller replacement and HVAC repair or replacement across city buildings for $7 million over three years (response due August 20, 2026); Williamson County's March 2026 competitive sealed proposal for Justice Complex Chiller Plant Upgrades budgeted at $580,000 (response due March 27, 2026); Orange County, Florida's chiller plant replacement project estimated at $3 million (response due July 30, 2026); and Monroe County's May 2026 RFP for countywide chiller maintenance and service across multiple locations (response due June 17, 2026). Georgia State University solicited mechanical contractor qualifications for two separate chiller replacements in June 2026. Most contracts require prevailing wage compliance, comprehensive bonding and insurance, and integration with existing building automation systems. Set-asides for small business or disadvantaged enterprises appear selectively but are not universal across all jurisdictions.
