NIGP 49306: Baths, Constant Temperature (Hot or Cold): Recirculating, Shaking, etc.

NIGP 49306 Baths, Constant Temperature (Hot Or Cold): Recirculating, Shaking, Etc. is an Item code under which state and local governments procure specialized water temperature control equipment for laboratory, research, and operational applications. Recent solicitations show actual buying concentrated on aquaculture and research facility heating and chilling systems — specifically multi-unit sealed-bid procurements for tank water temperature management in controlled environments where precision thermal control and corrosion resistance are mission-critical. The University of Southern Mississippi's procurement for its Oyster Hatchery and Research Center illustrates the scope: seventeen heater-chiller units across five capacity tiers (ranging from 6,000 to 120,000 BTUH) with titanium heat exchangers rated for saltwater use, digital temperature controllers, and integrated safety flow switches. Issuing bodies under this code include higher-education research institutions and county public health agencies, though recent activity in the block appears limited to a single concrete procurement action paired with a broader lab-systems RFI from Santa Clara County that does not directly specify temperature control equipment.

The University of Southern Mississippi issued an IFB (Bid #26-30, RFX 3160007920) posted March 2, 2026, with a response deadline of March 20, 2026, seeking new, unused current-production heater-chiller units with low-global warming potential refrigerant systems and FOB destination delivery with full assembly where practical; Aqua Logic Inc. was named as an acceptable manufacturer, though equivalent products meeting specification were invited. The source contains no additional recent opportunities under this code from other states or jurisdictions, no identified repeat buyers across multiple procurements, and no multi-state geographic activity to characterize.
