E-MAIL: Sandra Wheeler, sandra.wheeler-1@kmail.ksc.nasa.gov. EG&G Florida, Inc., in support of NASA at the Kennedy Space Center, is seeking sources to provide a Trailer Mounted High Pressure Breathing Air System Model 5407HBA-DT by Mako Breathing Air System or EQUAL. It must meet the following specifications. The compressor package shall be trailer mounted and designed to provide high pressure breathing air. The complete unit shall be factory assembled and tested. All components shall be housed within the confines of a sheet metal enclosure. All instrumentation and controls (compressor, fill station, engine and/or motor) shall be centrally located on the curbside of the trailer. The breathing air system shall include the compressor, diesel engine, purification system, DOT air storage system, SCBA/SCUBA fill station, controls, interconnecting piping, wiring and highway trailer as follows. The compressor block shall be four-stage, aircooled, pressure oil lubricated of "v" configuration and rated for continuous duty at 6000 PSIG with a charging rate of 20.7 CFM. Compressor systems requiring auxiliary cooling fans or cool down cycles shall be not acceptable. An oil level sight glass shall be provided for checking the crankcase oil level. An automatic drain system shall be supplied to periodically discharge accumulated condensation during operation and whenever the unit shuts down. The diesel engine shall be two cylinder, watercooled, pressure lubricated engine rated for a minimum 20 horsepower at 2600 RPM and the v-belt drive shall be guarded to meet OSHA requirements. The Purification System shall contain a visual moisture and carbon monoxide indicators on the operations panel. Systems requiring chamber depressurization to check filter condition shall not be acceptable. The purification system shall process 57,400 CF before cartridge replacement. The air delivered shall meet CGA grade "E" quality. The Control System shall be a unit to include all necessary controls to monitor compressor performance. As a minimum, the control system shall include the following -- high pressure switch with engine shutdown and restart light in order to maintain proper system pressure, high air temperature shutdown switch, and compressor low oil pressure shutdown switch. The DOT Air Storage System -- The breathing air storage system shall include four DOT air storage cylinders each with a minimum capacity of 590 cubic feet of air at 6000 PSIG. The system shall include all fittings, interconnecting piping, valves and hardware necessary to operate as a cascade system. The SCBA/SCUBA Fill Station shall be designed to permit the filling of two SCBA/SCUBA cylinders simultaneously. Two 5000 PSIG fill hoses with SCBA and SCUBA adapters shall be included. Wet filling capability is desired. Instrumentation/Fill Control Panel -- All gauges, lights and indicators shall be mounted on an operations panel readily accessible to the operator. The control panel shall accommodate optional accessories at a future date. The breathing air system control panel shall be centrally located and designed toallow the operator to visually monitor compressor performance, control air supply from the compressor and storage and fill SCBA and SCUBA cylinders. As a minimum, the control panel shall include the following compressor monitors: interstage and final air pressure gauges, oil pressure gauge, keyed power selector switch with panel illuminating power on light, hourmeter, high air temperature shutdown light, low oil pressure shutdown light, and compressor re-start warning light. The control panel shall also be designed to control the air supply function. The panel shall allow filling of two SCBA/SCUBA cylinders at a time and include a self-relieving 0-6000 psi regulator and gauges to indicate incoming air pressure, fill pressure, individual bottle pressure and two fill control valves. The panel shall also include pressure gauges and flow control vavles for two storage banks. Direct use of the compressor is also desired. The trailer shall be a DOT approved dual axle trailer with 14" wheels and designed for a minimum GVW of 7000 lbs. Vehicle hook up and appropriate lights for highway use are required. Accessories -- A sheet metal cabinet with vertically hinged doors and angled sleeves shall be provided for curbside storage of six SCBA cylinders, additional miscellaneous tool storage within the cabinet is desired, a spare wheel and tire and a retractable tongue dolly wheel. Carbon monixide monitoring system ounted on a centrally located control panel, must have a warning light, shall reliably direct CO concentrations from 0 to 50, and a calibration kit with 20 PPM co to be provided. The Purification System designed to monitor the quality of air being discharged is desired. Vendors who can meet these minimum specifications should send technical literature supporting their capability to EG&G Florida, Inc., Dept. BOC-110, Kennedy Space Center, FL 32899, Attn: Sandra Wheeler. Responses without requested technical data will be considered non-responsive. Responses must be received within fifteen days from date of publication. (0055)
