- Description
- THIS NOTICE CONSTITUTES AMENDMENT NO. 1 TO THE COMBINED SYNOPSIS/RFQ FOR DEEP VACCUM CHAMBER. 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 post questions and answers. 1. What size mechanical roughing pump will be supplied by NASA Goddard? Dry Mechanical Vacuum Pump: We are in the process of procuring a dry roughing pump like: Adixen Model ACP40 Or one similar that meets the following requirements: 1. pumping speed, minimum of 20 CFM 2. ultimate pressure, less than 50 x 10-2 torr 3. operating voltage,100-230VAC, 50/60hz, single or three phase. 4. Vacuum pump will have high reliability and require minimum routine maintenance. >>>> 2. External heating jacket: a. Is this a removable jacket? <<<< Our preference is to have it removable. >>>> b. Is the plan to install and remove this each time the chamber is cycled? <<<< We would most likely leave it installed on the chamber, unless we needed to access the chamber under the blanket. >>>> c. If the temperature controls are not part of this specification, what are they, who supplies them and how are they installed? <<<< We will provide the controller, necessary instrumentation and mounting in our control rack that is TBD. It would be too hard to try to specify all of the details that we would be required at this point. That said, the vendor is still responsible for the operation of the heating jacket at their facility with their equipment to verify that it works properly. The specification currently states: "The heating jacket will be able to uniformly heat the entire external surfaces of the chamber including the doors and feedthroughs. The heating jacket will be sized to heat the chamber to a maximum of 120C in a minimum of four hours. The temperature controls are not part of this specification. " We will ultimately provide all of the necessary equipment once the chamber is in our labs. Controlling the heating jacket was not an immediate need as it was driven by the ability to achieve ultra high vacuum, which is a future requirement. >>>> 3. In order to achieve the ultra high vacuum requested, we will need to bake out the chamber prior to shipment, so we will need to operate the bakeout heating jacket. What is the plan here? <<<< Our preference is for them to test and operate the heating jacket, so they can use it to bake-out the chamber. >>>> NOTE: THIS NOTICE WAS NOT POSTED TO FEDBIZOPPS ON THE DATE INDICATED IN THE NOTICE ITSELF (07-JUN-2007); HOWEVER, IT DID APPEAR IN THE FEDBIZOPPS FTP FEED ON THIS DATE. PLEASE CONTACT fbo.support@gsa.gov REGARDING THIS ISSUE.
