TECHNICAL CAPABILITIES STATEMENT

General Specification for One complete Chill Water System consisting of one 30-Ton chillers and one 60-Ton Chiller

Must be provided with the following capabilities, features and specifications: YES NO

Only fresh water will be circulated through the cooling system described above and shown in Figure (1).

Chill Water System must consist of at least three chillers. System must be able to support varying capacity from 30 to 90 tons of cooling capacity. System shall consist of one 30 Ton chiller and one 60 Ton Chiller.

System shall be able to allow isolation of each chiller separately to support varying chill water laods shipboard.

Must be air cooled.

Must be provided with the following capabilities, features and specifications: (Continued) YES NO

Must have a pumping system, consisting of at least two pumps. System must able to provide a variable supply of 30 to 500 GPM. Each pumping apparatus must be capable of maintaining 250 feet of head supply pressure, at all GPM ranges, at the contractor provided supply manifold. At a minimum, the pumping system shall have a minimum of 100 GPM at 100 feet of head pressure of redundant capacity. The expansion tank shall supply water directly to the pumps as shown in Figure (1). Additional pumps downsteam of the chiller unit(s) may be utilized to raise supply pressure to meet the required 250 feet of head pressure requirement at the contractor supplied supply manifold.

Must have suction and discharge manifolds with a quantity of ten (10) 2-1/2” MNPT supply connection and a quantity of ten (10) 2-1/2” MNPT discharge connections. All manifold connections shall have isolation globe valves installed. Manifolds shall include isolations valves to isolate the manifolds from the rest of the supplied chill water system.

Within the cooling loop there must be a reservoir capable of holding at least 250 gallons of cooling water or as required to support system design. Reservoir is required to account for small leaks.

Reservoir must be transparent in order to visibly verify the water level within the tank. Tank shall have a constant vent on the top or be open to the atmosphere to aid in bleeding air out of the chill water system.

System shall include a bypass line in order to flow water when no services are connected to the contractor supplied supply and discharge manifolds. This bypass line shall include globe valves so the flow can be throttled as required to suit ship’s demands and to keep the chiller units running under low flow/pressure conditions.

Desired output water temperature range is 55o - 65oF.

Must be operable on a single 460/480(V), 400 Amp Breaker (maximum).

Must be provided with a male 500 mcm Camlock electrical connection.

System must have necessary equipment to prevent freezing recurculating water with no cooling load at 0 O F.

CRITICAL SYSTEM SUPPORT: Unit must be capable of operating 24 Hours a day Seven

(7) Days a Week.

Must be operable at flow rates of as little as 30 GPM without needing to recirculate flow.

Contractor is to provide all equipment from the return manifold to the supply manifold. System shall be a complete unit. If pumps or tanks are separate, vendor will provide all piping/valves/fittings as required to couple pumps to the Chill Water Units. Vendor is to provide Extra fittings and hoses to support installation. If the system requies assembly, the system shall be assembled in such a way that it does not cause tripping hazards by minimizing the lengths of hoses between components. If lengths of hoses are longer than needed, it should be able to be coiled and put somewhere out of the way of normal foot traffic. Hoses shall be routed in a way that does not cause the hose to kink and reduce flowrate.

Provided hoses and manifold shall have insulation installed around them to reduce temperature losses in the chill water and to reduce the amount of condensation on the outside of the hoses when istalled shipboard.

Chiller Unit(s) must be capable of operating in an industrial environment where dust, dirt, and sea air are present.

Chiller Unit(s) to be equipped with operational Inlet and Outlet Temperature Gages.

Chiller Unit(s) to be equipped with operational Outlet Pressure Gage.

System is to include operational pressure gages on the contractor provided supply and discharge manifold.

Unit shall have an electronic monitoring system that monitors inlet and outlet temperature, pressure, and flow rate. The system shall be able to notify NNSY personnel when the monitored parameters fall outside of a set range.

If chiller system holds 55 gallons or more of fuel or oil or similar fluid, provide an environmental catch capable of holding at least 110% of the capacity of the fuel, oil, and other fluids required to operate the rental unit.

Evaporator must be capable of delivering a leaving temp of less than 65O F.

Condenser must be capable of operating in a wide ambient temperature range (0-125 O F)

Unit must be affixed with a metal tag designating the supplying company, a POC responsible for repairs and maintenance, and a phone number of the POC who is responsible for repairs and maintenance.

Contractor to adhere to the rigging requirements as outlined in Attachment B for contractor equipment at Norfolk Naval Shipyard.

The gross weight of the unit shall be clearly marked on the outside of the unit as outlined in Attachment B. If the unit is not a complete unit, the gross weight of each component shall be clearly marked on each component.
