  • Vacuum Breakers: Understanding how they protect

    2017-1-30 · Vacuum breakers should always be used on steam-to-water heat exchangers. They prevent condensate from being held up in the shell, which can lead to water hammer and tube damage. Steam-to-water convertors, or heat exchangers, heat the water in the tubes by condensing steam in the shell. When steam is present in the shell, the steam trap is closed.
