- Description
- The purpose of this amendment is to respond to technical questions submitted, incorporate technical changes and extend the due date for quotations. 1. The following question and response is hereby provided. Question: What is the requested chamber size or total unit dimensions? Answer: See revised technical specifications below under 2.1 and 2.2 2. Line Item 0001 is hereby amended to incorporate changes to the technical specifications as follows: 2.1 Specification 1 is hereby amended to add 1.9 as follows: FROM: 1) Furnace Chamber must contain the heating elements and hot zone material to 2100 degrees C: 1.1 Primary vacuum chamber material must be type 304 stainless steel with electro-polished internal Finish. All parts of the vacuum chamber shall be welded and/or brazed construction with non- magnetic and non-corroding material, vacuum-leak-tight to 1E-6 Torr ; 1.2 Hinged access port with at least 10 cm (4 in.) inner diameter (ID) free access; 1.3 Furnace chamber walls shall be water-cooled with all externally accessible surfaces maintained below 65 degree Celsius temperature. Additional water cooling must be provided for the Argon gas vented through the vacuum port at a rate of 1 to 2 liters per second as required to cool the hot zone as described in Sections 2.5and 4.8 1.4 Vacuum pump port with minimum 2.5 cm (1.0 in) ID; 1.5 Sight window for furnace interior with minimum 1.6 cm (0.62 in) viewing diameter; 1.6 One user access port with Conflat-type 2.5 cm (1.0 in) ID and blank flange seal; 1.7 Water-cooled power feed-throughs for heating elements, with all necessary power cables and heating elements installed; 1.8 Thermocouples and o-rings must be commercially available and of a non-proprietary design. TO: 1) Furnace Chamber must contain the heating elements and hot zone material to 2100 degrees C: 1.1 Primary vacuum chamber material must be type 304 stainless steel with electro-polished internal Finish. All parts of the vacuum chamber shall be welded and/or brazed construction with non-magnetic and non-corroding material, vacuum-leak-tight to 1E-6 Torr ; 1.2 Hinged access port with at least 10 cm (4 in.) inner diameter (ID) free access; 1.3 Furnace chamber walls shall be water-cooled with all externally accessible surfaces maintained below 65 degree Celsius temperature. Additional water cooling must be provided for the Argon gas vented through the vacuum port at a rate of 1 to 2 liters per second as required to cool the hot zone as described in Sections 2.5and 4.8 1.4 Vacuum pump port with minimum 2.5 cm (1.0 in) ID; 1.5 Sight window for furnace interior with minimum 1.6 cm (0.62 in) viewing diameter; 1.6 One user access port with Conflat-type 2.5 cm (1.0 in) ID and blank flange seal; 1.7 Water-cooled power feed-throughs for heating elements, with all necessary power cables and heating elements installed; 1.8 Thermocouples and o-rings must be commercially available and of a non-proprietary design. 1.9 The chamber shall be large enough to house the hot zone elements listed in section 2, with the minimum hot zone inner dimensions given in (2.1), and should provide all of the external access features listed in section 1. 2.2 Specification 6 is hereby amended to add 6.9 as follows: FROM: 6) Control console and cabinet housing furnace, power supply, and all controls: 6.1 Free standing cabinet must allow access to furnace and clear area for using sight window; 6.2 Water inlet supply and outlet discharge manifolds to distribute suitable purified cooling water to all parts of the system, with one or more manual one-quarter-turn ball valves for controlling flow to each part, with water lines and valves securely attached and accessible and with U.S. standardized fittings, with total water supply requirements specified; 6.3 One water flow sensor on the water discharge manifold to provide alarm input for temperature process controller if water-flow interruption occurs for more than 5 seconds; 6.4 Three-phase power line with U.S. standard power plug; 6.5 Step-down transformer to supply power for instruments and control circuitry; 6.6 Must give the user the ability to monitor current via analog or digital ammeter readouts for the hot zone heating elements; 6.7 Must give the user the ability to monitor voltage via analog or digital voltmeter readouts for the hot zone heating elements; 6.8 One flexible stainless-steel vacuum tube with Id at least 1 inch, of length 12', to connect the system to the User's vacuum pump (as defined in specification 4), terminated with a ISO-KF DN25 flange. TO: 6) Control console and cabinet housing furnace, power supply, and all controls: 6.1 Free standing cabinet must allow access to furnace and clear area for using sight window; 6.2 Water inlet supply and outlet discharge manifolds to distribute suitable purified cooling water to all parts of the system, with one or more manual one-quarter-turn ball valves for controlling flow to each part, with water lines and valves securely attached and accessible and with U.S. standardized fittings, with total water supply requirements specified; 6.3 One water flow sensor on the water discharge manifold to provide alarm input for temperature process controller if water-flow interruption occurs for more than 5 seconds; 6.4 Three-phase power line with U.S. standard power plug; 6.5 Step-down transformer to supply power for instruments and control circuitry; 6.6 Must give the user the ability to monitor current via analog or digital ammeter readouts for the hot zone heating elements; 6.7 Must give the user the ability to monitor voltage via analog or digital voltmeter readouts for the hot zone heating elements; 6.8 One flexible stainless-steel vacuum tube with Id at least 1 inch, of length 12', to connect the system to the User's vacuum pump (as defined in specification 4), terminated with a ISO-KF DN25 flange. 6.9 The overall size of the system cabinet shall be large enough to house the chamber and the control circuitry, power supply equipment, plumbing for water cooling and wiring. The vacuum pump will be some distance from the cabinet. 3. The due date for quotes has been changed as follows: FROM: June 14, 2010 @ 3pm EST TO: June 25, 2010 @ 3pm EST
