About this file
This is a technical specifications document for Bid #2630 issued by the University of Southern Mississippi for the procurement of aquaculture water temperature control equipment for an Oyster Hatchery and Research Center. The university is soliciting sealed bids for drop-in water chillers, air-cooled reversible heat pump units, and commercial-duty heat/chill pump systems. The equipment specifications call for three low-profile drop-in water chillers with 6,000 BTUH cooling capacity and 115V single-phase electrical service; four air-cooled reversible heat pump/chiller units with identical cooling capacity and electrical requirements; six medium-capacity units rated at 5 tons (60,000 BTUH) with 208-240V single-phase power; two large-capacity units rated at 7.5 tons (90,000 BTUH) with 208-240V three-phase power; and two extra-large capacity units rated at 10 tons (120,000 BTUH) with 208-240V three-phase power, for a total of 17 units. All equipment must be new, unused, current production models suitable for marine and freshwater aquaculture research environments capable of continuous-duty operation in humid, corrosive coastal conditions.
The specifications require all equipment to feature titanium heat exchangers suitable for saltwater use, corrosion-resistant construction, digital temperature controllers, and integrated safety flow switches. Units requiring refrigerant must include pricing for low-global warming potential refrigerant systems such as R454B or approved equivalents. Delivery is FOB destination to the University of Southern Mississippi with full assembly required where practical and advance coordination mandated prior to shipment. The university identifies Aqua Logic Inc., a manufacturer of titanium heat pumps and water chillers, as an acceptable manufacturer, though comparable quality products meeting the established specifications will be considered. The document reserves the university's right to determine product equivalency, allowing flexibility in bidder submissions while maintaining established performance and quality standards.
