43 -- AIR COMPRESSORS SOL 00SQ110009 DUE 070500 POC Ernie Bachman, Mechanical Engineer, 208-334-9561, Marie Day, Purchasing Agent 208-334-1744 E-MAIL: MDAY@PN.USBR.GOV, MDAY@PN.USBR.GOV. This is a combined synopsis/solicitation for a commercial item requirement in accordance with the format FAR Subpart 12.6 as supplemented with additional information included in this notice. This announcement constitutes Solicitation No. 00SQ110009 issued as an RFQ and incorporates provisions and clauses in effect through FAC 97-18. NAICS code is 333912 and the size standard is 750 employees. Anderson Ranch and Black Canyon Powerplant Station Air Compressor Replacement Anderson Ranch Dam and Powerplant are located on the South Fork of the Boise River, approximately 70 miles upstream of Boise, Idaho. Black Canyon Dam and Powerplant are located on the Payette River, seven miles northeast of Emmett, Idaho. Both dams and powerplants are operated and maintained by the U.S. Bureau of Reclamation, Snake River Area Office. The powerplants are both operated from the control center at Black Canyon Dam. Existing Compressors: Anderson Ranch Powerplant: Currently, there are two station service compressors locatedin the air compressor room. They supply 100 psi air for the operation of the generator air brakes, air tools, turbine generator greasing system, emergency air to the OCB air systems in the switchyard, and other plant maintenance requiring high pressure air. Air for both compressors is drawn through an air inlet filter located in the wall of the lower level gallery. Both compressors discharge to a common air header and receiver tank, for air distribution throughout the powerplant. The receiver tank has a capacity of approximately 375 gal. Each compressor is water-cooled, has its own water-cooled air after cooler and a moisture separator. One of the compressors is a 65-cfm, belt-driven, 400 rpm, single stage, water-cooled, oil-lubricated, reciprocating unit, driven by a 25 hp, 1,770 rpm motor. The other compressor is a 125 cfm, belt-driven, 325 rpm, single stage, water-cooled, oil-lubricated, reciprocating unit, driven by a 40 hp, 1,780 rpm motor. The two air compressors are operated in a lead-lag configuration, with the lead compressor operating between 95 psi and 110 psi, and the lag compressor between 70 and 85 psi. Either compressor can operate as the lead or lag. Black Canyon Station Air Compressor Replacement: There is one designated station service air compressor, which supplies 100 psi air for the operation of the generator air brakes, air tools, turbine generator greasing system, and other plant maintenance requiring pressurized air. The compressor is a 2-cylinder, 2-stage, air-cooled, oil lubricated, belt-driven compressor, powered by a 25 hp motor with an output of about 65 cfm at 110 psi and operates between 80 and 120 psi. The air receiver tank for this compressor has a capacity of approximately 110 gal. Requirement: Because of general aging and difficulty to maintain the current compressors and a need for increased capacity, the government requires replacing them with four (4) Single Stage, Rotary Screw, Base-mounted, Stationary Air Compressors. Two will be used at Anderson Ranch Powerplant, and two at Black Canyon Powerplant, allowing a lead-lag configuration at both powerplants. At both facilities the lead compressor will start at 95 psi decreasing pressure, and stop at 110 psi increasing pressure. The lag compressor will start at 70 psi decreasing pressure, and stop at 85 psi increasing pressure. (This will change the operating criteria at Black Canyon). Either compressor at each facility shall be useable as either the lead or lag. All four compressors will be located in a dry interior plant environment, with reasonably clean supply air and operating conditions. A list of the requirements for four identical compressors follows: 1. Compressor: Each unit shall be a single stage, base-mounted, lubricated rotary screw compressor, with a capacity of 125 acfm continuous output at 100 PSIG and capable of operating at 125 PSIG. Each compressor shall have tapered roller bearings on the discharge and suction end of each rotor. The driven shaft shall have a triple lip seal. To prolong bearing life the unit shall be lubricated with a synthetic lubricant having a minimum life of 6,000 hours operating time under normal conditions. 2. Motor: 480 V, 3-phase, 60 Hz, induction motor, with a minimum of 1.15 service factor, and class "F" insulation,. Include magnetic motor starter, non-reversing, with thermal overload, "Auto-off-Manual" selector switch, 120-volt AC actuation with 480-volt to 120-volt transformer in NEMA 4 or 12 enclosure. Please specify the motor horsepower on your unit, required to achieve the required capacity. 3. Base: Complete compressor unit mounted on a single heavy duty steel base. 4. Controls: Dual Control: The compressors will normally start in an unloaded condition and will unload on shut-down. However, the controller shall also allow each unit to run continuously either fully loaded or unloaded. Lead/lag control of the two compressors at each location shall be provided, with the lead/lag designation of each compressor field-adjustable. 5. Drive: Multiple V-belt or direct drive. If belt drive,must have an automatic belt tensioning device which maintains correct belt tension, and an OSHA V-belt guard. 6. Filters: A. Spin-on type lubricant filter with indicator. Include three extra filter elements. B. Inlet air filter with indicator and silencer. Include three extra filter elements. 7. Cooling: A. Air- cooled lubricant cooler with automatic temperature control to maintain the coolant between 170 and 190 degrees F. under normal ambient temperatures. B. Air cooled air-aftercooler, which cools compressed air to within 15-20 degrees F. of the ambient temperature. 8. Separators: A. Two-stage air-lubricant separator reducing oil levels in air to less than or equal to 3 ppm. Lubricant separator element indicator. B. Moisture separator with automatic drain trap. 9. Instrumentation: A. Power-on light. B. Discharge air pressure gauge calibrated from 0 -- 200 psi. C. Lubricant Level Gauge. D. Lubricant Temperature Gauge. E. Hour Meter (Run and Loaded) 10. Protective Devices: A. ASME Pressure Relief Valve. B. Discharge Air Check Valve, downstream from the relief valve. C. Unit Shut-down on the following conditions: Motor Overload; High Air/lubricant Temperature; and Loss of Drive. Each function shall have a visual indicator and an electrically isolated dry contact to supply output for our powerplant annunciation and SCADA system. 11. Performance Data: Prospective bidders shall supply complete performance data, including capacity in ACFM at 100 PSIG, and at 125 PSIG, brake horsepower under full load conditions, rotor speed, and all other applicable data. 12. Miscellaneous: Each compressor unit shall come complete and ready to perform. All items, such as internal piping and wiring, initial lubricant supply, steel base with all equipment permanently mounted, and a coupling guard shall be included to assure proper operation of the unit. 13. Size Limitation: Each of the four units must fit through an opening no greater than 46" wide by 82" tall. 14. Warranty: Please specify the length of standard warranty for motor and air/end.
