About this file
This is a Vendor Compliance Checklist that establishes the technical and performance requirements for a temporary dehumidification system rental at Portsmouth Naval Shipyard. The checklist outlines two configuration options: a primary system with four Desiccant Climate Controlled Units (DCCU) rated at 10,000 CFM each, and an alternate system with three DCCU units rated at 15,000 CFM each. Both configurations require a 230-ton air-cooled chiller, a 600 GPM chilled water pump, associated piping assemblies, fittings, and manifolds to support the pre-cooling and post-cooling functions. The primary DCCU units must deliver a minimum of 10,000 CFM at 12 inches of water gauge with 70 tons nominal cooling capacity, while alternate units must deliver 15,000 CFM at 10 inches of water gauge with 100 tons nominal cooling capacity. All equipment must be frame/skid-mounted with maximum dimensions and weights specified, require dual 460-volt AC, three-phase, 400-amp circuits for power, and 100 PSIG steam at 338°F for desiccant reactivation.
The checklist specifies that all equipment must be pre-wired with remote emergency stop (E-Stop) capability, delivered fully charged and assembled, and include lifting and handling certification with padeyes. The vendor is responsible for providing qualified technician support with 24-hour response time and 48-hour repair completion, all preventative maintenance and weekly inspections, a comprehensive preventative maintenance plan, operator training for shipyard personnel, and complete technical documentation including operations and maintenance manuals, equipment data sheets, hydrostatic pressure test reports, and a Machinery Quality Checklist with objective quality evidence of functional performance testing. The chiller must incorporate automatic variable capacity control, maintain discharge temperature at 42°F, and achieve maximum energy efficiency of 2.5 amperes per ton of chilled water capacity. All machinery must arrive free of coolant in piping systems.
