E-MAIL: Janet K. Reese, jreese@wstf.nasa.gov. This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in 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. This procurement is being conducted under the Simplified Acquisition Procedures (SAP). NASA JSC White Sands Test Facility intends to purchase three (3) identical HVAC units manufactured and delivered on or before April 7, 1999. Each unit will have indirect/direct evaporative cooling and gas fired heating. Each will be factory assembled and mounted on a common 6-inch skid. The fan will be able to provide 1.00 inch of External Static Pressure for 8,000 acfm in summer and 4,000 acfm in winter at 5,000 ft. elevation. The unit will be able to cool 8,000 acfm supply air from 1000 F. entering to 64.30 F. leaving air temperature or better. The gas fired heating section will provide 198 MBH output heat at 5,000 ft. elevation and 4,000 acfm air flow. Heating section firing efficiency shall be no less than 80% at sea level. Provide Vari-Cool ID-4D/RMUA 400 or equal units. Equipment & Performance Data shall be submitted for the units consisting of use life, power ratings, capacity ranges, face area classifications and rotational velocities. Manufacturer's catalog data and drawings shall be submitted for the following: evaporative media; fans, controls, casings, dampers, filters, furnaces, insulation, motors, pumps, spare parts, and vibration isolation. Submit 6 copies of the O&M manuals 30 days before delivery of units. UNIT INFORMATION If a supplier provides models as called out in this specification, it does not relieve them of having to meet the entire specification. Units are to be furnished factory assembled. Unit maximum outside dimensions shall be 26'5" by 9' 9", which includes 2' clearance for intakes. The return must fall within 5' and 9' from the OSA intake. The indirect section shall be 60% efficient or better with maximum .2" WG air side pressure drop. The direct section shall be 90% efficient or better with maximum .13" WG air side pressure drop and maximum 400 fpm face velocity. All motors are to be high efficiency motors with thermal protection. Power connection is to be single point wiring. The maximum noise level outside the units must be 75 db or less, 1' from unit. The units shall be assembled so that the OSA flow goes through the following circuit: indirect section; direct section; return/damper/filter section; fan section and furnace section. The indirect and direct sections shall not have water carryover into downstream sections nor leak water into adjacent sections and shall have 20 gauge 304 stainless steel pans. The evaporative media will be CELdek. or approved equal. The furnace heat exchangers shall be all electric welded construction with Type 409 stainless steel, .044" tubes and .050" header plates. Gas and electric components shall consist of not less than the following: main gas cock; main gas pressure regulator; main solenoid gas valve; pilot gas cock; pilot gas pressure regulator; pilot solenoid gas valve; intermittent spark ignition system; high limit control and 24 volt control transformer. Unit Controls: A remote control panel will be provided which includes ON-OFF and SUMMER-OFF-WINTER manual switches. The ON-OFF provides start/stop of the main fan. The SUMMER selection cycles the dampers (RA closed, OSA open) and enables the pumps. The WINTER selection enables the furnace and allows the dampers to reverse (RA open, OSA partially open). A room thermostat (by others) provides two stages of cooling and one of heating. Stage 1 cooling turns on the spray pump. Stage 2 turns on the indirect section pump and fan. Stage 1 heating enables high fire of the furnace. Internal furnace controls will provide modulated burner control to maintain a constant supply air temperature, manually adjustable from 60 to 100 degrees. The internal furnace controls will also provide all safety interlocks. Float valves shall be brass body and stem, adjustable water make-up float and be factory furnished and installed. Pumps are to be UL listed, permanently lubricated, 115V, 60 Hz, 1 phase, and factory piped. The indirect and direct sections shall have 1" minimum drain and overflow connections. All factory furnished plastics are to be UV protected. The dampers shall be opposed blade, positive close-off AMCA certified dampers with electric operators and shall be provided on both the OSA and return. The maximum leakage of dampers will be 8 cfm per square foot at 4 inches SP WG. The filter face velocity shall not exceed 500 fpm. Filters shall have an average efficiency of not less than 36% per NBS performance tests. Fans (Blowers) shall be centrifugal-type. Bearings shall be anti-friction type, and have AFBMA 11, L-10 life expectancy rating of 200,000 hours. Fans shall be forwardly curved, double width, double inlet Class 1. Fans shall be V-belt driven by 2-speed motors of sufficient size that the brake power rating shall not exceed the nominal motor rating. Adjustable sheave shall provide not less than 20% fan-speed adjustment. Sheave size shall be selected so that fan speed at the approximate midpoint of the sheave adjustment will produce the specified air quantity. The driver and driven sheaves shall be of the keyed hub type. The driven sheave shall be of a fixed pitch diameter and the driver shall be a variable pitch diameter sheave and shall be sized for 135% of motor horsepower. Motors shall be 480V, 3 phase, 60 Hz high efficiency type. Vibration isolation shall be sized and provided based on the unit provided. Fans shall be statically and dynamically balanced. Manufacturer shall run each unit under load and perform vibration analysis to confirm the unit balance. Measurements and test equipment shall conform to ANSI S2.2, ANSI S2.17, and ANSI S2.41. Measurements shall be made on or near each bearing and shall not exceed 2 mils displacement peak-to-peak nor 0.3 in/sec overall velocity. A test report for each unit shall be provided showing the measurements versus location in tabulated form. Units must be made and assembled in the United States. The basic cabinetry of the indirect and direct sections will be constructed of 20 gauge aluminized steel with a primed and enamel finish inside and out. Fasteners will be stainless steel. Primary and secondary air flow duct connections will be flanged. Mounting rails will be provided in order to secure the unit. Accessibility from both sides of each unit will be provided to all service areas. All grease fittings for internally mounted equipment will be extended to outside the cabinets.
