UNSPSC 41104502: Gravity convection ovens

UNSPSC 41104502 Gravity convection ovens is a Commodity code that covers laboratory and shop-floor ovens with forced-air or mechanical convection circulation, as documented in recent state and local solicitations. State and local governments buy these units primarily for transportation and public health laboratory applications—materials testing, asphalt characterization, and sample processing—and for maintenance facilities requiring controlled-temperature equipment storage and curing. Recent opportunities show buyers issuing detailed technical specifications for oven capacity, power requirements, temperature uniformity, digital control systems, and safety certification. The issuing bodies are primarily state departments of transportation and environmental agencies, with some municipal utility and public health involvement. Texas Department of Transportation (TxDOT) has posted multiple bids under this code in recent weeks, as has the Illinois Department of Transportation (IDOT) District 6.

Activity concentrates in Texas and Illinois. TxDOT's Childress District solicited a mechanical convection oven (Solicitation 601340000066612, due July 23, 2026), and TxDOT's Abilene District bid laboratory ovens and NCAT asphalt furnaces (Solicitation 601340000066278, due July 13, 2026, posted June 22, 2026). IDOT District 6 posted a rebid for a 28 cubic foot forced air laboratory oven (Solicitation 27494DOTFINADB52856, due June 25, 2026, posted June 15, 2026) requiring stainless steel interior construction, single-phase 230-volt power at maximum 50 amps, forced-air circulation, operating range from ambient plus 15 degrees Celsius to 300 degrees Celsius minimum, temperature uniformity within 2.5 degrees Celsius, temperature stability within 0.3 degrees Celsius, digital PID temperature control with 0.1 degree Celsius resolution, over-temperature protection, UL listing or equivalent certification, and $1 million general liability insurance. Texas vendors must register on the Euna Procurement platform and the Texas Comptroller of Public Accounts Centralized Master Bidders List with applicable NIGP codes before submission; Illinois bids require compliance with prevailing wage and state standard terms and conditions governing insurance, record retention, and termination for convenience.
