The prior art vacuum system required 9 condensers and six ejectors to maintain the appropriate vacuum levels in three chambers

Basic ejector design is known in the art and is described in Roper, D. and Ryans, J. Process Vacuum System Design and Operation, McGraw-Hill Book Company, New York, 1986. However, the break pressure ranges necessary can not be achieved using ejectors with standard break pressures commonly supplied by equipment manufacturers. The prior art vacuum system required 9 condensers and six ejectors to maintain the appropriate vacuum levels in three chambers. The single train system of the present invention utilizes only four ‘condensers (one of which is optional precondenser (23)) and three ejectors to provide the same vacuum levels to three chambers.
