NIGP 19051: Heat Transfer Media, Liquid

NIGP 19051 Heat Transfer Media, Liquid is an Item code under which state and local governments procure heat-transfer fluids and related chemical media, including copper sulfate in crystal and liquid forms for industrial cooling, water treatment, and specialized thermal-management applications. The code encompasses both commodity chemicals and engineered heat-transfer solutions used across municipal utilities, county facilities, and industrial support functions.

Pasco County, Florida recently issued RFQ RFQFP261004 on June 3, 2026, soliciting large copper sulfate crystals and liquid copper sulfate on an as-needed basis, with proposals due June 26, 2026. The county intends to contract with one or more vendors under this indefinite-quantity arrangement. Activity under the code remains limited in the recent-opportunities record, with no additional issuing bodies or geographic clusters visible. The absence of broader solicitation activity suggests either narrow demand concentration or light procurement velocity in this commodity class across state and local jurisdictions at present.
