- The Solicitation number is F1S0AZ7131B001. This is a combined synopsis/solicitation for commercial items prepared IAW the format in FAR Subpart 12.6 as supplemented with additional information included in this notice. This announcement constitutes the only solicitation. This is a request for quotation (RFQ). The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular (FAC) 2005-17 and DFARs Change Notice (DCN) 2007-04-26. Standard Industrial Classification (SIC) code is 3585. NAICS is 333415 and the size standard is 750 employees This acquisition is a 100% small business set aside. The 412 TW, Edwards Air Force Base, CA is seeking the to purchase the following items as a Brand Name or Equal purchase: Line 1: Part # B47489-1 Cooling System (Quantity 1 Each); Line 2: Installation and setup; Performance Criteria / Specification: ?The total wgt of the system (2 MMCU's + power supplies + mounting trays + shock mounts + cover + water manifold/lines) will be ~125 lbs; ?Dimensions = 17.7? x 17.7? x 27.9?; ?At 24VDC and 120?F ambient, total max current draw (system running 'all out') will be ~50 A; ?At 24VDC and 120?F ambient, max cooling power will be ~2100 W. If they run both power supplies at 28VDC, then total max current draw will be ~55 A and max cooling power will be ~2300 W; Compressor insensitivity to orientation; The compressor maintains adequate lubrication, ensuring long-life without requiring a gravity-dependent sump like most commercially available compressors; Automatic Ambient Temperature Compensation; Internal digital controller monitors ambient air temperature and automatically adjusts system gain as ambient temperature (and cooling demand) increases; Can be customized to suit specific customer cooling requirements; On-site electronic troubleshooting capability; Port enables communication with the internal controller via laptop (or any computer with RS-232 connector and Hyper-terminal). Controller firmware code parameters facilitate on-site troubleshooting: Motor fault detection; Real-time system voltage and motor current draws (pump, fan, compressor); On/off command of discreet components; Cumulative hours in use; Components sealed against rain, sand, dust; The internal Fan features an IP-68 protection level rating; The compressor, water pump, and controller are fully sealed against entry of water or other environmental particulates / contaminants; High Ambient Temperature Capability; System functional up to 145?F ambient air temperature; Controller electronics designed to withstand high temperatures and harsh environments; Commercially available controllers are typically only rated to 113?F; STATEMENT OF WORK (SOW) FOR WEIBEL RADAR COOLING SYSTEM: Scope; The 412th RANS Flight Test Center at Edwards Air Force Base (AFB), CA is currently installing a small liquid cooled Weibel radar system on a refurbished L3 Communications Brashear KINETO Tracking Mount (KTM). The KTM is a fast response tracker capable of reaching unloaded angular speeds of 60?/sec and accelerations of 100?/sec2. The estimated top angular speed/acceleration for the KTM loaded with the radar is 40?/sec and 60?/sec2. The KTM is built with electrical slip rings to allow continuous rotation. There are no provisions for liquid cooling in the slip ring, so the chiller will have to be mounted on the moving surface. The older chiller could not withstand being rotated about two axis and did not have the capacity to cool the radar on hot days. Requirements General; The contractor shall design, engineer, build and deliver a chiller that cools the Weibel radar system (P/N: MFDR-2100/37) while in operation on the KTM; The chiller shall be a self contained vapor compressor based technology with an air cooled condenser. The refrigerant shall cool a closed loop liquid coolant. The chiller shall provide a circulating pump to circulate the liquid coolant to the radar unit; The chiller shall have 1800 watts of cooling capacity or greater at an ambient condition of 120 degrees Fahrenheit; The chiller shall accommodate lower cooling requirements and automatically adjust accordingly so that the radar system will be operating in its normal temperature range. Depending on the radar target and ambient conditions the 1800 watts may be reduced by a quarter; The cooling liquid shall be water with antifreeze (glycol) mix; The chiller shall deliver a flow rate greater then 1 gallon per minute. The output pressure shall not exceed 60 PSI. The radar has ?? hose fitting. There can be a static pressure to accommodate tilting of the unit, but the static pressure shall not exceed 7 PSI; The chiller shall fit into a space that is 17.7? H x 17.7? W x 28? L. The hose and electrical connections shall accommodate the KTM and should be designed to fit into the confined space. Both the 17.7? square sides are generally open to accommodate air circulation and connections. The maximum weight of the unit can be 100 pounds; The chiller shall function while undergoing angular accelerations of up to 60?/sec2 in two axes of rotation. The maximum angular acceleration in each axis should not last more then a half a second for each occurrence. The angular velocity will top out at 40?/sec and should not last more than 5 seconds for each occurrence; The chiller shall be insensitive to dynamic orientation. The chiller will be tilted in the longest dimension from -5 to 95 degrees in reference to ground level. The chiller will also be moving around in the azimuth plane 360 degrees continuously while being tilted. The plan is to mount the chiller near the center of rotation in the azimuth axis. The chiller will be mounted approximately 18? below the center of rotation in the elevation axis; The chiller shall be designed to withstand occasional vibrations and shocks from typical transportation on unimproved road conditions (dirt and gravel roads); The chiller shall be built for outdoor use. The KTM/radar and chiller will typically be covered with a weather resistant fiberglass shell, but could be uncovered at times for up to a week. Rodents are a problem at Edwards AFB and the chiller shall be built to withstand rodent infestation; The chiller shall be designed to accommodate the KTM power capability. The KTM slip ring can accommodate different power requirements. Two circuits of 120 VAC are available; each circuit is #16 AWG and should support 15 amps of continuous current (30 amps surge for .1 seconds). There are four #10 AWG slip rings that can support any voltage up to 208 volts. The #10 AWG slip rings are rated at 25 amps of continuous current (50 amps surge for .1 seconds); The chiller?s controls shall be easy to turn on/off and setup; The chiller?s status indicators shall be designed to allow remote access. A PC Windows based computer (2.8 GHz, 512 MB of RAM, XP) used for controlling functionality of the KTM and radar could be used for remote access of the chiller. For safety reasons, personnel need to stay 100 feet away from the active radar. The chiller?s front panel will not be visible to the operator. Switch closure sensors are preferred for the operator interfacing to other KTM/radar equipment; Materials, sub-assemblies and manufacturing shall meet industry best practices; Acceptance testing at Edwards AFB shall be conducted to verify the requirements have been met; Documentation; The contractor shall comprehensively schedule and track progress against milestones of the design, engineering, fabrication and delivery; The contractor shall provide a user manual. The user manual shall include installation, wiring, interface instructions, troubleshooting guide and periodic maintenance instructions; Engineering drawings of the chiller unit are NOT a requirement; These recorders are used to support real-time mission telemetry data recording and playback missions along with testing in the control rooms.
