An ejector is a simple, robust fluid-handling device that uses a high-pressure motive stream to entrain and compress a secondary flow. Ejectors are used in refrigeration, vacuum systems, steam systems, and process plants because they have no moving parts, are low-maintenance, and can handle mixed-phase flows. A well-crafted fixed Excel (XLS) calculation workbook captures the essential design steps, lets engineers iterate quickly, and serves as a repeatable record for sizing and performance prediction.
