UNSPSC 40101711: Centrifugal liquid chiller

A type of refrigeration unit which changes the kinetic energy of refrigerant gas to pressure using the centrifugal force of an impeller rotating at high speed. It consists of a compressor, condenser and evaporator, and its refrigerating capacity is large. It isalso called a turbo refrigerator.

UNSPSC 40101711 Centrifugal liquid chiller is a Commodity code representing equipment replacement, maintenance, and repair services that state and local governments procure for their building and facility operations. Recent solicitations show school districts, counties, cities, universities, and transit authorities issuing competitive bids and RFPs for chiller replacement projects ranging from single-unit installations to multi-location system upgrades, as well as multi-year preventative maintenance and emergency repair contracts covering existing chiller fleets. Scope of work spans turnkey replacement of air-cooled and water-cooled centrifugal chillers with associated piping, controls, electrical integration, and commissioning; major overhauls and refurbishment of high-hour equipment; and ongoing preventative maintenance with 24/7 emergency response capability. Vendors typically must hold state mechanical contractor licenses, maintain EPA refrigerant certifications for all technicians, provide factory certifications for specific chiller manufacturers (Trane, Carrier, York, Dunham-Bush), carry commercial general liability insurance (often $1 million per occurrence or higher), and respond to emergency calls within two to four hours. Issuing bodies include K-12 school districts (Cherokee County School District in Georgia, Pinellas County Schools in Florida, Houston Independent School District, Klein ISD in Texas), public universities (University of Southern Mississippi, Georgia State University, University of Houston), county governments and authorities (Broward County Aviation Department, Orange County Florida, Monroe County Florida, Catoosa County Georgia), cities (Charlotte, Phoenix, St. Petersburg, Long Beach, College Park), and state agencies (Florida DCF, Oregon DAS, Texas HHS Commission).

Geographic activity concentrates in Florida (multiple school districts and county procurements), Texas (school districts and universities), Georgia (universities and county government), and the broader Southeast, with recent activity also in California, Oregon, and Mississippi. Representative recent opportunities include Pinellas County Schools issuing sealed IFBs for chiller replacement at two locations (Oldsmar Elementary and another site) with bids due July 8 and July 10, 2026, specifying water-cooled screw chillers with detailed refrigerant, piping, and safety system requirements; Orange County, Florida issuing a sealed IFB for Administration Center HVAC Chiller Plant Upgrades with estimated contract value of $3,000,000 and bids due September 1, 2026; Broward County Aviation Department issuing an open-end indefinite-quantity ITB for central energy plant and HVAC equipment preventative maintenance, inspections, and repairs across five airport terminals with $1.11 million annual pass-through allowances for parts and materials and mandatory 24/7 emergency response, due October 7, 2026; the City of Charlotte issuing an RFP for preventative maintenance and repair services on existing Trane, Pulse, Aalon, Carrier, and Lochinvar chillers at CATS facilities, due October 15, 2026; and the State of Florida Department of Children and Facilities issuing an ITB for HVAC preventive maintenance and repair at the Roberts Building in Jacksonville, with a mandatory pre-bid meeting on June 8, 2026 and proposals due July 15, 2026. Procurement preferences and set-asides vary by jurisdiction—Broward County applies SBE and CBE preferences within ten percent of the lowest bid, and some solicitations reserve consideration for Service Disabled Veteran-owned businesses, though most do not identify specific disadvantaged-enterprise restrictions.
