UNSPSC 40101836: Shell and tube heat exchanger

UNSPSC 40101836 Shell and tube heat exchanger (Commodity) spans chiller replacement and maintenance work that state and local governments are actively procuring across school districts, counties, cities, universities, and transit authorities. Recent solicitations frame the commodity not as a standalone equipment purchase but as the mechanical core of broader chiller plant upgrades, replacements, and preventative-maintenance contracts. State and local buyers are soliciting turnkey chiller replacement services that include shell-and-tube heat exchanger components as part of complete system installations—cooling towers, piping, controls, electrical integration, and commissioning—often with fixed-price or time-and-materials service agreements for ongoing maintenance and emergency repair. The issuing bodies span a wide mix: school districts (Cherokee County School District in Georgia, Pinellas County School District in Florida, Klein Independent School District in Texas), counties (Broward County Aviation Department in Florida, Orange County in Florida, Monroe County in Florida, Catoosa County in Georgia), cities (City of Charlotte, City of Phoenix, City of St. Petersburg in Florida, Long Beach Public Utilities), state agencies (State of Oregon Department of Administrative Services, Texas Health and Human Services Commission), and universities (University of Southern Mississippi, University of Houston, Texas A&M University, Georgia State University).

Geographic activity concentrates in Florida (Pinellas, Orange, Monroe, Broward counties and St. Petersburg) and the Southeast (Georgia, Texas) with additional activity in the Pacific Northwest (Oregon), Southwest (Arizona, California), and upper Midwest. Representative recent solicitations include Pinellas County School District issuing an IFB for chiller replacement at Oldsmar Elementary School with a water-cooled screw chiller system and detailed piping and refrigerant specifications (bids due July 10, 2026 via OpenGov e-Procurement); Orange County, Florida issuing a sealed-bid IFB for Administration Center HVAC Chiller Plant Upgrades with an estimated contract value of $3 million, requiring replacement of three existing chillers with Trane oil-free magnetic bearing water-cooled units and R-513A refrigerant (bids due September 1, 2026); Broward County Aviation Department issuing an open-end indefinite-quantity ITB for central energy plants and related HVAC equipment maintenance, inspections, repairs, refurbishment, and rental services at Fort Lauderdale-Hollywood International Airport with a Small Business Enterprise procurement preference and $1.11 million in annual pass-through allowances for parts, permits, and specialized equipment (proposals due October 7, 2026); and Monroe County Board of County Commissioners in Florida issuing an RFP for countywide chiller maintenance and service at multiple locations with a 100-point scoring system emphasizing cost, qualifications, and staff credentials (proposals due June 17, 2026). Chiller maintenance contracts frequently carry five-year terms with optional renewals, require 24/7 emergency response capability, mandated preventative maintenance windows, and certification requirements for technicians (EPA Section 608, manufacturer-specific factory training for Trane, Carrier, York, and Dunham-Bush units). Many jurisdictions reference State of Florida Department of Management Services cooperative-purchasing pricing or leverage existing state contracts during evaluation.
