UNSPSC 41104504: Cleanroom ovens

UNSPSC 41104504 Cleanroom ovens, a Commodity code, covers laboratory ovens and furnaces that state and local governments procure for materials testing, asphalt analysis, and quality assurance work — specifically forced-air convection ovens with precise temperature control, stainless steel construction, and performance specifications tailored to transportation and infrastructure testing standards. State transportation departments drive the recent activity under this code; the Texas Department of Transportation (TxDOT) has posted multiple IFB solicitations for laboratory ovens and NCAT asphalt-content furnaces across its Abilene and Childress districts, while the Illinois Department of Transportation (IDOT) District 6 has solicited forced-air lab ovens. Equipment is typically specified by exterior and interior dimensions, operating temperature range, temperature uniformity and stability tolerances, power requirements (commonly single-phase 230V or 240V, 60Hz), and control systems with digital displays and PID capability. Vendors must often provide alternative-product literature and detailed specifications when proposing substitutes for named models such as the Gilson BO-355ERS or AP-20. Deliverables frequently include original manuals, parts lists, calibration documentation, and warranty coverage.

Recent activity concentrates in Texas and Illinois. TxDOT Abilene District's IFB 601340000066830 (due August 6, 2026) requests two 10.6-cubic-foot digital ovens with forced-air convection and three NCAT Asphalt Content Furnaces meeting ASTM D6307 and AASHTO T308 standards, with delivery to 4250 North Clack, Abilene, Texas 79601 and acceptance requiring 15 consecutive failure-free operating days post-installation. An earlier TxDOT Abilene solicitation (601340000066278, due July 13, 2026) and a Childress District mechanical convection oven IFB (601340000066612, due July 23, 2026) indicate ongoing replacement or expansion activity across TxDOT's testing infrastructure. IDOT District 6 posted a rebid for a 28 cubic foot forced-air lab oven (27494DOTFINADB52856, due June 25, 2026) and an earlier FY26 solicitation (26494DOTFINADB52235, due May 8, 2026), both requiring single-phase 230V power, temperature uniformity within 2.5 degrees Celsius, and stainless steel interiors, with delivery to 2420 South Dirksen Parkway, Springfield, Illinois 62703. All solicitations require registration on state procurement portals (TxDOT uses Euna Procurement/Bonfire Hub; IDOT uses its standard portal) and compliance with state bidding registries (Texas Comptroller of Public Accounts' Centralized Master Bidders List for TxDOT; Illinois prevailing wage and compliance requirements for IDOT). TxDOT applies Texas vendor preferences for in-state production, USA-made equipment, and service-disabled veteran-owned businesses when responsive bids are tied on price.
