The unit must meet the specification: 125-ton air-cooled helical rotary water chiller similar to or equal to Trane model number RTAA1254X. Voltage for the unit shall be 460-volts/60 hertz/3 phase. Unit shall be provided with aluminum fins with a sprayed corrosion coating. The unit shall have a minimum Energy Efficiency Ratio (EER) of 9.3 and a minimum Integrated Part Load Value (IPLV) 12.5 in accordance with ARI 550 for scroll and screw packages. The unit shall be capable of operating during low ambient conditions with temperatures down to 25 degree Fahrenheit. Unit shall come with five-year parts and labor warranty. Unit shall be delivered to the government ten days after the order is placed. Government personnel will install unit. The unit will be replaced as part of a scheduled shutdown or curtailment of operations within the facility. The factory start-up of the unit shall be scheduled to coincide with the shutdown to limit the down time. Unit panels, structural elements and control boxes are constructed of 12-gauge galvanized steel and mounted on a welded structural steel base. Unit panels and control boxes shall be finished with baked-on powder paint, and the structural base with and air-dry paint. The evaporator shall be a tube-in-shell heat transfer design with internally finned copper tubes roller expanded into the tube sheet. The evaporator shall be designed, tested and stamped in accordance with ASME for a refrigerant side working pressure of 300 psig and a waterside working pressure of 215 psig. Water connections shall be grooved pipe. Each shell shall include a vent, a drain, and fittings for temperature control sensors and shall be insulated with ?-inch Armaflex II or equal insulation (K=0.26). Heat tape with thermostat shall be provided to protect the evaporator from freezing at ambient temperatures down to ?20 degrees Fahrenheit. Air-cooled condenser coils shall have aluminum fins mechanically bonded to internally finned copper tubing. The condenser coil shall have an integral sub cooling circuit and shall provide oil cooling for the compressor bearing and infection oil. Condensers shall be factory leak tested at 506 psig. Condensers shall be two rows deep and 100% coated with a protective coating to protect the condensers from corrosion. Condenser fans shall have direct drive three phase motors with permanently lubricated ball bearing and internal thermal protection. Compressor started shall be an across-the-line configuration factory mounted and completely prewired to the compressor motor. Compressor starters shall be enclosed in a weather tight enclosure. The rotary screw compressor shall be semi-hermetic, direct drive, twin steel screw design, 3600 rpm, with step and variable load and unloader valves for capacity control, rolling element bearings, differential refrigerant pressure oil pump and oil heater. The compressor motor shall be suction gas cooled, hermetically sealed, two pole squirrel cage induction motor. Oil separation shall be provided separate from the compressor and oil filtration shall be accomplished with and integral oil filter located within the compressor. The unit shall have two independent refrigerant circuits, with one rotary screw compressor per circuit. Each refrigerant circuit shall 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. Refrigerant shall be R22. The unit shall be factory leak tested and precharged with a complete charge of refrigerant and oil. In lieu of precharging the unit the complete charge of refrigerant and oil can be installed as part of the factory startup. The compressor and electronic expansion valve shall provide variable capacity modulation over the entire operating range with infinite un-loading from 100 to 25 percent. All unit controls shall be housed in a weather-tight enclosure. All controls, including sensors, shall be factory mounted and tested prior to shipment. The unit shall be provided with Microcomputer controls which control all functions including start up and shut down, leaving chilled water temperature control, compressor and electronic expansion valve modulation, fan sequencing, anti-recycle logic, automatic lead/lag compressor starting and load limiting. The unit control module shall automatically take action to avoid unit shutdown due to abnormal operation conditions associated with low refrigerant temperatures, high condensing temperature and motor current overload. Controls shall provide protective functions for loss of chilled water flow, evaporator freezing, 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. Unit shall be provided with menu driven digital display, which indicates the operating data points, and alarm conditions. Controls shall be capable of being connected to the building automatic control system for remote chilled water set point and demand limiting by accepting a 4-20mA or 0-10Vdc analog signals. Control power shall be provided from a factory installed power transformer. The following clauses and provisions are incorporated and will remain in full force in any resultant award.
