24' x 30' vacuum chamber-40' high with lid. 7/8" stainless steel. Certified vacuum test by ASME Engineer.  Use whole or reuse as scrap. Chamber History: Build in 1960 by Chicago Bridge & Iron (CBI) under contract number 8-3190. Designed to simulate an ultimate altitude of 760,000 feet (5x10-7 Torr) and temperature environment from -185 to 120 degree C. Inside free workspace is 24 feet in diameter by 21 feet, 6 inches high. Entrance is gained through a removable top lid that is mounted on its own bridge crane, and a seven foot main door. Vacuum vessel constructed of 300 series stainless steel with carbon steel stiffeners. Interior shrouds are constructed of aluminum and are blackened with Chemglaze Z306 Black. Chamber wall was optically dense to the workspace. Vacuum system consisted of 2 roughing packages, each containing a 500 CFM roughing pump backed by a 5,000 CFM roots blower. Refrigerated cold traps prevented migration of rough pump oil to the chamber. High vacuum pumping system consisted of four 36" cryopumps, with each pump isolated from the chamber by means of a high vacuum slide valve. Thermal shrouds were divided into six zones (4 sides, 1 top and 1 bottom). Aluminum floor grating is capable of supporting 200 pound per square foot. Four main hard points are located in the center of the chamber floor.
