UNSPSC 41104502: Gravity convection ovens

UNSPSC 41104502 Gravity convection ovens, a Commodity code, encompasses laboratory and materials-testing ovens that state and local governments procure for transportation departments, public works facilities, and materials-science operations. Recent solicitations show that state and local buyers are acquiring forced-air and mechanical convection ovens for asphalt content testing, materials analysis, and laboratory applications, often paired with specialized furnaces and accessories meeting ASTM or AASHTO standards. The work includes supply of new equipment with digital temperature control, stainless steel interiors, UL certification, comprehensive warranties, installation support, and post-delivery acceptance testing. Issuing bodies are dominated by state transportation departments—specifically the Texas Department of Transportation (TxDOT) across multiple districts and the Illinois Department of Transportation (IDOT) District 6—each posting multiple solicitations for similar or overlapping equipment needs over the past four months.

Recent activity concentrates in Texas and Illinois. TxDOT has posted at least three IFBs since mid-June 2026: a June 22 posting for the Abilene District (IFB 601340000066278, due July 13, 2026); a July 2 posting for the Childress District (601340000066612, due July 23, 2026); and a July 23 posting for the Abilene District again (IFB 601340000066830, due August 6, 2026), which solicits two 10.6-cubic-foot forced-air ovens with UL-listed digital controllers, three NCAT asphalt furnaces meeting ASTM D6307 and AASHTO T308 standards, and three furnace starter kits. IDOT District 6 posted for 28 cubic foot forced-air laboratory ovens twice: May 4, 2026 (due May 8, 2026) and June 15, 2026 (due June 25, 2026). Both TxDOT and IDOT solicitations emphasize "or approved equal" language, requiring bidders to provide detailed product literature and compliance documentation when proposing alternatives. TxDOT applicants must register on the Centralized Master Bidders List (CMBL) and submit through the Euna Procurement/Bonfire Hub portal; IDOT requires compliance with Illinois Standard Terms and Conditions, including prevailing wage and federal fund record retention where applicable.
