UNSPSC 40101838: Economizer

An economizer is a heat exchange device that heats a fluid up to (but not beyond) the boiling point of that fluid

UNSPSC 40101838 Economizer is a Commodity code that names equipment used to recover waste heat or reduce energy consumption in heating, ventilation, and air-conditioning systems. State and local governments buy economizers as discrete mechanical components installed as part of HVAC retrofit and new construction projects, often in concert with broader system replacements, controls upgrades, and facility renovations. The solicitations tracked under this code show economizers primarily appearing as line items within larger HVAC modernization contracts rather than as standalone procurements; they are specified as factory-installed or field-integrated components of rooftop units, packaged systems, and chilled-water plants.

State and local buyers for economizer-related work span city, county, and special-district procurement entities. Cities issue the largest volume of opportunities—Bartow, St. Petersburg, Lubbock, and Roswell post recurring HVAC service and replacement ITBs and RFPs. Counties—Forsyth, Orange, Harris, Gwinnett, Broward, and Clay in the South; Lapeer and Carrollton in Michigan; Hillsborough and Bergen in the Northeast—regularly solicit HVAC system modernization. School districts and community colleges (Anchor Bay Schools, Lane Community College, Habersham County Board of Education, Cherokee County Schools) pursue phased HVAC upgrades. State agencies and correctional systems (Texas Department of Criminal Justice, Texas Health and Human Services Commission, Texas Military Department, Texas Southern University) execute large-scale inmate-housing and facilities HVAC replacements where economizers may be specified. The most active recent issuers are Texas jurisdictions and Georgia counties. Representative recent opportunities include the City of Bartow ITB 26-22 for HVAC installation, repairs, and emergency services across municipal facilities (responses due August 5, 2026); the Texas Health and Human Services Commission RFB for preventative maintenance and repair of HVAC equipment at Rio Grande State Center in Harlingen (responses due July 31, 2026); the City of St. Petersburg IFB-26-262 for three-year HVAC preventative maintenance across municipal buildings (responses due August 6, 2026); and Broward County Aviation Department's request for replacement of 22 rooftop HVAC units on Terminal 3 at Fort Lauderdale-Hollywood International Airport with a $20 million general liability and performance-bond requirement (responses due July 29, 2026). Geographic concentration is heaviest in Texas, Florida, Georgia, and Michigan, with secondary activity in the Northeast and Pacific Northwest. Economizer procurement typically occurs as part of the bid response for the enclosing HVAC system or controls package rather than as a separate commodity request; the code shows lower standalone activity than parent HVAC families, reflecting that economizers are almost universally factory-integrated into equipment specifications rather than purchased independently.
