E-MAIL: Veronica C. Stubbs, Veronica.C.Stubbs.1@gsfc.nasa.gov. THIS NOTICE CONSTITUTES AMENDMENT NO. ONE (1) TO THE COMBINED SYNOPSIS/RFQ FOR ELECTRIC BOX FURNACE. Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued. The purpose of this amendment is to incorporate the detailed Specifications along with the Statement of Work into the synopsis/RFQ. Statement of Work Deliver to Goddard Space Flight Center (GSFC) an electric Box Furnace with highly uniform temperature control to a maximum temperature of 1,1000C. The interior working dimension (uniform temperature volume) shall be at least 60" wide, 48" high, and 60" deep. GSFC expects that the actual interior dimensions would be approximately 12" larger in width and depth and 24" larger in height than the working dimensions. The Box Furnace shall have a hearth with dimensions 60" wide by 60" deep. The hearth shall be capable of withstanding about 2500 lbs., and the hearth height shall be 32" above the floor. The case shall be atmosphere tight and shall be fitted for inert atmosphere blanketing protection of the work piece. The furnace shall have a door that opens vertically upwards. GSFC expects that the Furnace will consume approximately 155 kW of power. The power configuration will be 480 Volts, 3-phase, 60 Hz. Control voltage will be 120 VAC, derived by step-down transformer from the 480 VAC. The Box Furnace shall have a multi-zone digital temperature controller with at least eight (8) zones of control. There shall be a separate high limit digital controller. Temperature uniformity shall be within 150C at temperatures above 6000C. Temperature uniformity shall be within 1100C at temperatures below 6000C. SPECIFICATIONS AND PERFORMANCE REQUIREMENTS. Technical Descriptions and Requirements Case Construction 7 Case shall be atmosphere tight for inert gas environment. 7 Case shall be of welded steel construction. 7 Case shall have lifting eyes. 7 Case shall have leveling bolts and anchoring holes at the feet. 7 Case shall be primed and painted using materials appropriate for the likely case temperatures. 7 A port shall be provided on the outside of the case that can accommodate a minimum of 8 or 9 survey thermocouples, so that a uniformity survey can be made. 7 An external heat shield to keep the case temperature below 500C shall be provided Insulation 7 There shall be no asbestos or asbestos-containing products used in the construction of the Furnace. 7 The insulation shall limit the outside case temperature to no more than 10% of the interior temperature at 6000C, and no more than 15% of the interior temperature at the maximum temperature. The Door 7 The Furnace door shall open vertically and upwards such that the interior box is fully open. 7 The door shall be triple gasketed in order to meet the atmosphere-tight requirements. 7 Door motion toward or away from the gasket seal shall be horizontal to avoid scraping the seal surfaces. 7 The door shall be counterbalanced and lifted by an electric motor drive. 7 The door shall have pneumatic clamps to provide the pressure required to seal the volume. Hearth and Loading System 7 A hearth with castable refractory piers shall be provided Electrical System 7 Controls shall be mounted in a floor-standing NEMA 12 panel with full length hinged door. The panel shall be equipped with a fused disconnect. 7 The control panel shall have a provision for tagout/lockout per OSHA regulations. 7 All wiring shall meet the National Electrical Code. 7 The control panel shall be mounted on the right, with the controls facing front. 7 All wiring shall terminate in a terminal strip or strips. 7 All wiring shall be numbered at both ends with printed wire markers. 7 All other components shall be clearly identified with labels or markers inside the cabinet. Labels shall correspond to the electrical diagram. 7 Switches, controls, and pilot lights on the front panel shall be labeled with engraved labels. 7 A permanent metal nameplate with the manufacturer's name, address, phone number, model number, serial number, and all electrical properties shall be affixed to the Furnace case. 7 A door cut-off switch shall be implemented, so that power will be removed from the heaters if the Furnace door is opened. 7 All wiring shall be done using wire with insulation appropriate for the temperatures likely to be encountered. Controller 7 The Furnace shall be equipped with a digital programmable multi-loop temperature controller. 7 The controller shall implement at least eight (8) control loops or zones in the Furnace. 7 The controller shall be a Proportional Integral Differential (PID) controller with programmable tuning parameters. 7 The controller shall provide for programmed cycles of ramps and soaks. The controller shall be capable of operating up to 4 such programs simultaneously. 7 The controller shall include thermocouple burnout protection. Over-temperature Control 7 The Furnace shall be equipped with a separate digital high temperature limit controller. 7 The high limit controller shall provide for programmable maximum temperature. 7 The high limit controller shall require manual reset upon activation. 7 The high limit controller shall include thermocouple burnout protection. Thermocouples 7 All control thermocouples shall be Inconel-sheathed Type K. 7 Separate thermocouples shall be used for the main controller and the high limit controller. Data Logger 7 The system shall include the capability to monitor and log data from up to 12 survey thermocouples 7 Thermocouple-to-data-logger interface shall be via a jack panel. Instruction Manual An instruction manual shall be included along with documentation to cover the following: 7 Start-up instructions 7 Theory of operation 7 Maintenance instructions 7 Atmosphere conditioning instructions 7 Atmosphere flow diagrams and parts list 7 Troubleshooting guide 7 Main and sub-assembly drawings 7 Wiring diagram(s) 7 Control panel layout 7 Control and component manuals/instructions and cut sheets 7 Recommended parts list Setup and Startup Responsibilities 7 Customer responsibilities (GSFC) 7 Provide proper foundations at the site 7 Provide proper utilities (power, atmosphere gases, etc) 7 Install, level and anchor the equipment 7 Assemble the delivered sub-assemblies 7 Hook up all utilities according to drawings provided by the Contractor 7 If necessary, interconnect power wires from control panel to the Furnace. 7 Process definitions Contractor responsibilities 7 Check out and leak-test the atmosphere system 7 Inspect the Customer's assembly of the Furnace. Make recommendations as needed for changes or corrections. 7 Check for and repair any refractory cracks 7 Check for overall integrity of the system 7 Perform the initial startup 7 Make any adjustments necessary for proper operation The due date for receipt of offers is not extended.
