NIGP 67024: Liquid Heaters, Immersion Type

NIGP 67024 Liquid Heaters, Immersion Type is an Item code that covers chemical treatment supplies and equipment used by state and local water, wastewater, and public health departments. Recent state and local solicitations under this code show procurement of copper sulfate crystals and liquid copper sulfate for water treatment and algae control applications. The issuing bodies soliciting under this code include county governments and water-adjacent special-purpose districts. Pasco County, Florida, exemplifies the typical buyer profile — a mid-sized county seeking reliable suppliers for routine chemical consumables on an as-needed basis through indefinite-quantity arrangements.

Copper sulfate procurement activity appears concentrated in Florida, as evidenced by Pasco County's June 2026 RFQ for large copper sulfate crystals and liquid copper sulfate with a June 26, 2026 response deadline. This represents a direct, routine acquisition of treatment chemicals rather than equipment procurement, suggesting the NIGP code's scope in practice reflects the consumable chemical supply side of immersion-based water treatment rather than thermal heating equipment. The indefinite-quantity structure and as-needed ordering model are standard for this commodity across local water and environmental management operations.
