UNSPSC 40101712: Screw chiller

A type of refrigeration unit which compresses gas in the course of reducing the capacity of refrigerant gas by the high-speed rotation of the rotor of a compressor with a male screw and a female screw engaged with each other.

UNSPSC 40101712 Screw chiller is a Commodity code that encompasses the supply, installation, maintenance, and repair of screw-type refrigeration chillers serving municipal facilities, educational institutions, utilities, and county government buildings. State and local governments procure screw chillers as replacements for aged or failed units, as components of comprehensive chiller plant modernizations, and through ongoing maintenance contracts covering emergency repair and preventative service. The issuing bodies span school districts, city and county facilities departments, utilities, universities, and special-purpose districts, with recent activity concentrated among Florida jurisdictions (Pinellas County Schools, Orange County, City of St. Petersburg, Volusia County, Monroe County), Texas counties (Williamson County), Georgia institutions (Georgia State University, Hall County, Glynn County), and scattered opportunities in Oregon, Mississippi, California, and Washington. Repeat buyers include Pinellas County Schools (two chiller replacement bids within the past month) and Williamson County (multiple mechanical systems upgrades including chiller plant work), signaling ongoing capital replacement cycles at anchor facilities.

Recent solicitations show state and local governments buying screw chiller services through a mix of procurement vehicles. Orange County, Florida issued a $3,000,000 sealed-bid IFB for Administration Center HVAC Chiller Plant Upgrades specifying Trane oil-free magnetic bearing screw chillers with R-513A refrigerant, with responses due July 30, 2026. The City of St. Petersburg released RFQ26292 for Building Operations and Maintenance covering multiple work categories including chiller replacement across city-wide locations, with qualifications due August 20, 2026 and a $7,000,000 total budget allocation structured as a three-year continuing services agreement with two optional one-year renewals. Pinellas County Schools issued back-to-back sealed electronic bids for chiller replacement at specific school sites (IFB bids due July 8, 2026 and July 10, 2026), both utilizing the State of Florida Department of Management Services pricing vehicles. Monroe County, Florida's RFP633 (responses due June 17, 2026) seeks countywide chiller maintenance and service across multiple locations using a 100-point evaluation system weighted toward qualifications and staff credentials. Texas jurisdictions including Williamson County and the City of College Park are procuring complete chiller plant turnkey installations with mechanical, electrical, and building automation system integration. Contractors bidding on screw chiller work face qualification hurdles including five-plus years of commercial HVAC experience, state licensing, manufacturer certifications, comprehensive insurance (typically $1,000,000–$2,000,000 general liability), performance and payment bonds, and prevailing wage compliance where applicable. Geographic activity clusters in Florida (Orange, Pinellas, Volusia, Monroe counties and the City of St. Petersburg) and Texas (Williamson County), with secondary activity in Georgia, Oregon, Mississippi, and California reflecting distributed capital equipment replacement schedules across state and local assets.
