Steam ejectors deliver precise control of the atmosphere and pressure in a system. These are highly useful in chemical processing, vacuum sealing, and food packaging, as well as various processes in power, oil, and gas. Steam ejectors can also be used to create vacuum conditions in large areas where a conventional vacuum pump is inadequate. The steam ejector injects high-temperature and pressure steam into a system at a high velocity. The steam expels other gases from the system, creating a low-pressure vacuum inside the system.
