Description
The University of Southern Mississippi is soliciting sealed bids for the purchase and delivery of a heater chiller system for the Oyster Hatchery and Research Center. The system includes drop-in water chillers, air-cooled reversible heat pumps, and commercial-duty heat/chill pump units. The equipment must be new, unused, and of current production, and must meet certain minimum performance and quality standards. The university reserves the right to determine equivalency. The system will be used in a marine and freshwater aquaculture research environment and must operate reliably in humid and corrosive coastal conditions.
Some key features and requirements of the system include:
• Compact, low-profile drop-in configuration
• Air-cooled design
• Nominal cooling capacity of approximately 6,000 BTUH
• Motor rating of approximately 0.5 HP
• Electrical service of 115V, single phase
• Maximum operating current of approximately 9.5 amps
• Integrated digital temperature controller
• Single-stage control operation
• Hydraulic performance with a water flow range of 12-25 GPM
• Approximate dimensions of 17-18 in. in length, 15-16 in. in width, and 13-14 in. in height
• Heat or chill capability in a single unit
• Titanium heat exchanger suitable for saltwater use
• Corrosion-resistant construction
• Digital temperature controller
• Outdoor-rated control enclosure (NEMA 4X or equivalent)
• Integrated safety flow switch
• Stainless steel or corrosion-resistant stand
