This is a combined synopsis/solicitation for commercial items prepared in accordance with the format FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; quotes are being requested and a written solicitation will not be issued. Solicitation No. 1425-98-17-08590 is issued as a Request for Quotation (RFQ) and incorporates provisions in effect through Federal Acquisition Circular 97-01. This acquisition is a Small Business set-aside. The size standard is 750 employees and the standard industrial classification code is 3585. U.S. Bureau of Reclamation, Grand Coulee, Washington has a fixed price requirement for the following items: CLIN 0001 -- Chiller (Air Conditioning Unit), 100 ton, Trane Model No. RTWA100, or equal -- 1 Each, Specifications as follows: Unit is to be leak and pressure tested to at least 450 psig on the high side and to at least 300 psig on the low side, then evacuated and charged. Unit is to be shipped with a full operating charge of oil and refrigerant (HCFC-22). Evaporator is to be a tube-in-shell heat transfer design with internally finned copper tubes roller expanded into the tube sheet. Evaporator is to be designed, tested and stamped in accordance with ASME for a refrigerant side working pressure of at least 300 psig. The evaporator is to be designed for a water side working pressure of at least 215 psig. Each shell will include a vent, a drain and fittings for temperature control sensors and is to be insulated with at least 3/4 inch of Armaflex II, or equal, insulation. Condenser is to be a tube-in-shell heat transfer design with seamless internally/externally finned tubes expanded into the tube sheet. Condenser is to be designed, tested and stamped in accordance with ASME for a refrigerant side working pressure of at least 450 psig. The condenser is to be designed for a water side working pressure of at least 150 psig. Each tube bundle will be cleanable and replaceable. Compressor and Oil Lube System -- The compressor will come with a rotary screw compressor that is semi-hermetic, direct drive, with step and variable load and unload valves for capacity control, rolling element bearings, differential refrigerant pressure oil pump and oil heater. Refrigerant Circuits -- The chiller package will have two independent refrigerant circuits, with one compressor per circuit. Each refrigerant circuit will include a compressor suction service valve, discharge service valve, liquid line shutoff valve, removable core filter drier, liquid line sight glass with moisture indicator, charging port and an electronic expansion valve. Unit Controls -- All unit controls will be housed in a weather-tight enclosure. Microcomputer controls will provide all control functions including start-up and shut down, leaving chilled water temperature control, compressor and electronic expansion valve modulation, anti-recycle logic, automatic lead/lag compressor starting and load limiting at the minimum. The controls willalso automatically take action to avoid unit shutdown due to abnormal operating conditions associated with low refrigerant temperatures, high condensing temperatures and motor current overload. If the conditions do not correct then the unit will shutdown. Controls, Protective, Functions -- Unit protective functions will include at the least loss of chilled water flow, evaporator freezing, condenser entering and leaving water temperatures, low refrigerant pressure, high refrigerant pressure, reverse rotation, compressor starting and running over current, phase loss, phase imbalance, phase reversal, high motor winding temperature, high oil temperature, and loss of oil flow. The control will provide water regulating valve with head pressure control for low entering condenser water temperature. The unit will have a menu driven digital display that indicate operating data points including chilled water set point, current limit set point, leaving chilled water temperature, evaporator and condenser refrigerant temperature and pressures, compressor total operating hours and starts. Diagnostic checks will be made, saved/stored, and displayed when a problem is detected. The digital display must have the capacity to be read and advanced on the unit without opening any control panel doors. Standard power connections must include 460 volt/60 hertz/3 phase main power not to exceed 225 amps and115 volt single phase power connections for control power. Control Power Transformer -- A control power transformer will be factory installed and wired. Across the line starter. Chiller unit capacity 110 tons. Chilled leaving water temperature 44 degree F. Chilled water flow rate 300 gpm. Condenser water maximum flow rate 340 gpm. Condenser water entering temperature may at be below 60 degree F. For sizing purposes an entering temperature of 75 degree F will used. Chiller unit overall dimensions will fit within an envelope 6 foot high by 3foot wide by 9 foot long.
