UNSPSC 40101861: Preheater

Preheater is a general term to describe any device designed to preheat the combustion air used in a fuel-burning furnace for the purpose of increasing the thermal efficiency of the furnace. Various types of preheaters are Dry / Wet /heat, air and gas.

UNSPSC 40101861 Preheater is a Commodity code. State and local governments buying under this code are primarily purchasing heating equipment for facility operations, though the recent solicitation record shows limited direct activity. The Talbot County, Georgia Fire Department solicitation for split heat pump systems (IFB, March 2026) represents the clearest match to thermal equipment procurement; the Sourcewell cooperative RFP for Law Enforcement Equipment (RFP #061626, June 2026) appears to be a broad-scope solicitation unlikely to include preheater-specific equipment. Issuing bodies soliciting under or adjacent to this code span county governments and special-purpose districts managing facility maintenance and equipment replacement.

Geographic activity is sparse and scattered. Talbot County, Georgia posted the only recent opportunity with direct relevance to heating system procurement. The Sourcewell cooperative RFP involves multiple Washington state counties (Franklin, Grant, Grays Harbor, Chelan, Yakima) but targets law enforcement equipment rather than preheating systems. No state-level repeat buyers or regional concentration emerges from the available record. The Williamson County, Texas notice (July 2026) is an administrative relocation announcement with no procurement scope and should be disregarded. Overall, the code shows minimal recent solicitation activity at the state and local level; opportunities tagged under 40101861 are infrequent, and when they do appear, they often diverge from preheater scope or reflect broader equipment categories bundled into cooperative purchasing frameworks.
