This solicitation document and the incorporated provisions and clauses are those in effect through Federal Acquisition Circular 90-46. All responsible sources may submit a quote which will be considered. The Standard Industrial Classification Code is 5075. The small business size standard is no more than 100 employees. SCHEDULE: LINE ITEM NUMBER 1: Air Cooled Reciprocating Liquid Chiller QUANTITY: 1 each STATEMENT OF WORK/SPECIFICATIONS: The contractor will deliver to the Federal Correctional Institution (FCI) located in Fort Dix, New Jersey, one (1) Air Cooled Reciprocating Liquid Chiller, to include one (1) set of installation, operation and maintenance manuals. STATEMENT OF WORK/SPECIFICATION: Air cooled reciprocating liquid chiller unit. This is a packaged unit. Capacity range 75 -- 85 ton, 200 volts, 3 phase, 60hz. R22 refrigerant to include disconnect switch, vibration isolators and flow switch. GENERAL: The packaged air cooled chiller will be completely factory assembled including all interconnecting refrigerant piping and internal wiring of controls, mounted on a steel base which accommodates the air cooled condenser, compressor and cooler. A factory run test of the refrigeration circuits will include operation with water flowing through the cooler. Unit structure will be constructed of galvanized steel and painted with weather resistant enamel. The unit must have a full operating charge of R22. The unit will separate refrigerant circuits, each with a single compressor for standby operation. The unit shall be designed and constructed in accordance with the applicable sections of the following: Air Conditioning and Refrigeration Standard ARI 590; American Society of Heating, Refrigeration and Air Conditioning Engineers ANSI/ASHRAE 15 Safety Code for Mechanical Refrigeration; American Society of Mechanical Engineers ASME Pressure Vessel Code; National Electrical Code/National Fire Protection Association NFPA 70; Underwriters Laboratories U.L. 1995 (200, 230, and 460-2-60); and Canadian Standards Association. HERMETIC MOTOR COMPRESSOR: Maximum of one compressor per refrigerant circuit. The compressors will be accessible hermetic reciprocating type with all rotating parts statically and dynamically balanced. The compressor will include stainless steel, ring type suction and discharge valves and removable cylinder liners. Motor cover and cylinder heads (with internal muffling devises) will be removable. The compressor will have a force fed lubrication system using a reversible positive-displacement type oil pump. The crankshaft will be ductile (nodular) iron, drilled for positive oil distribution, with integral counter-weights for balancing. The main bearings will be the insert type, steel backed babbitt and the thrust bearing will be bronze. The compressor will also include a suction strainer, oil strainer, crankcase oil sight glasses, crankcase oil heater, and back seating seal-cap type suction and discharge stop valves. The compressors will be mounted on isolators. The hermetic motor will be high torque, part winding start, 1750 rpm, 60 HZ or 1470 rpm, 50 Hz refrigerant gas-cooled and will be equipped with internal temperature sensing overtemp protection in each phase. The rain-tight motor terminal box will be located above the crankcase oil level. CAPACITY CONTROL SYSTEM: The capacity control system will modulate compressor capacity automatically by using solenoid actuated control valves with high pressure oil. Unloading will be controlled by the control center. EVAPORATOR: The evaporator will be a direct expansion shell and tube type with refrigerant in the tubes and liquid to be chilled in the shell. The design working pressure of the cooler shell (liquid) side will be a minimum of 150 psig, and a minimum of 235 psig for the tube (refrigerant) side. Refrigerant heads will be removable. The cooler will be equipped with a heater cable, covered with 3/4" flexible closed cell foam insulation (.025 max) for freeze up protection to -20 degrees F ambient. The cooler will be constructed and tested in accordance with ASME Code requirements. Vent and drain will be included. The water connections will be fully accessible and grooved to accept victaulic couplings. CONDENSER COILS: The condenser coils will be constructed of seamless copper tubes, arranged in staggered rows, mechanically expanded into aluminum fins and include an integral subcooling section. The design working pressure of the condenser coil will be a minimum of 450 psig. CONDENSER FANS AND MOTORS: The condenser fans will be propeller type, providing vertical air discharge. Fan blades will be statically and dynamically balanced, protected above by PVC coated fan blade guards (50-90 ton model will have zinc dichromate coating with lacquer overcoat). REFRIGERANT CIRCUITS: The unit will contain two separate refrigerant circuits and each will be constructed of ACR copper tubing and brazed joints, and will include: shut off valve with charging connection, liquid sight glass with moisture indicator, direct acting maximum operating pressure thermal expansion valve, solenoid valve and filter-drier. The entire suction line and liquid line between the expansion valve and the cooler will be insulated with flexible closed cell insulation. POWER PANEL: The power panel will contain the compressor power terminals, general purpose compressor motor starting contactor, current transformer sensing for each compressor power source, for protection against under voltage, over voltage, imbalanced voltage, single phasing compressor stall and voltage spikes, fan contactors with overload current protection and control power supply terminal strip with fuse protection for 115-1-50/60. DISCONNECT SWITCH: A factory mounted unit disconnect switch with external handle (in compliance with Article 440-12 of NEC) shall be supplied to isolate unit from power voltage for servicing. FLOW SWITCH: NEMA 4x switch (150 psig DWP), -20 degree Fahrenheit to 250 degrees Fahrenheit with 1" NPT connection for up-right mounting in horizontal pipe. VIBRATION ISOLATION: Vibration isolators shall be provided for field mounting. Isolators will be level adjusting spring type with 1" deflection.
