UNSPSC 40101828: Cartridge heaters

UNSPSC 40101828 Cartridge heaters, a Commodity code, shows minimal recent activity specifically aligned to cartridge heating elements in state and local procurement. The two posted opportunities bearing this code involve electrical work and boiler-chiller maintenance services — neither represents direct procurement of cartridge heater products. Northside Independent School District (San Antonio) issued an RFQ on September 22, 2026 for an indefinite quantity contract covering general electrical work at district facilities, with sealed bids due October 15, 2026; this replaces an expiring contract under RFP 2022-143 and requires all vendors to respond or risk losing incumbent status. The City of Charlotte posted an RFP on the same date for preventative maintenance and repair services on boiler and chiller systems across CATS facilities, also due October 15, 2026, specifying certified technician requirements and access to proprietary parts for manufacturers including Trane, Pulse, Aalon, Carrier, and Lochinvar — neither solicitation explicitly identifies cartridge heaters as a line item or component procurement.

The geographic footprint visible under this code spans Texas and North Carolina based on the two substantive postings, but the activity level does not support a robust market signal. The three other records in the recent-opportunity block — a Williamson County administrative relocation notice, a Sourcewell cooperative purchasing RFP for law enforcement equipment (unrelated to cartridge heaters), and a City of Lavonia water treatment plant construction project — further indicate that the code is receiving mistagged or incidental use in state and local procurement systems. No current contract value, term, set-asides, or explicit demand for cartridge heater products emerges from the record. Firms should verify whether opportunities posted under this code actually specify heating cartridge procurement or represent tagging errors, and monitor for more specific, commodity-aligned solicitations before committing capture resources.
