NIGP 03130: Dehumidifiers and Humidifiers

NIGP 03130 Dehumidifiers and Humidifiers, an Item code, encompasses equipment and services for moisture control in public facilities, including the removal, replacement, and maintenance of humidifiers and dehumidifiers as components of broader HVAC and climate-control projects. State and local governments procure dehumidifiers and humidifiers as standalone replacements within facility-renovation scopes and as integrated elements of heating, ventilation, and air-conditioning system upgrades. Issuing bodies soliciting under this code include state transportation departments, county facilities offices, and municipal transit authorities managing climate control across office buildings, maintenance facilities, and public-facing administrative spaces.

Recent activity shows limited but concentrated solicitation. The California Department of Transportation (Caltrans) Division 11 issued an Invitation for Price Quote (IFPQ) on May 11, 2026, requiring removal and replacement of one humidifier and one dehumidifier as part of a broader HVAC replacement project at the District 11 Museum in San Diego, California, with quotes due May 18, 2026 and restricted to certified small business, microbusiness, or disabled veteran business enterprise contractors. The City of Charlotte issued an RFP (Solicitation 26920271769) on September 22, 2026, for preventative maintenance and repair services on boiler and chiller systems at CATS facilities in Charlotte and Mecklenburg County, with proposals due October 15, 2026; while the primary focus is boiler and chiller equipment, the scope includes potential upgrades and installations to climate-control systems where dehumidifiers and humidifiers may be ancillary. Geographic activity centers on California and North Carolina, with broader multi-jurisdictional participation through cooperative purchasing vehicles such as Sourcewell supporting potential law-enforcement and facilities equipment procurement nationwide. The code shows low recent posting volume and appears concentrated in state transportation departments and municipal transit authorities.
