  • Vacuum Breakers for steam systems | UK | Spirax Sarco

    A vacuum breaker will prevent the boiler from flooding as a result of the steam condensing internally and creating a vacuum after boiler shut down. The breaker allows air to enter the shell, breaking the intense vacuum. This system is a must for boilers connected to a condensate return tank. The vacuum breaker consists of a spring loaded disc and associated piping and is factory plumbed to the boiler. System ES89369 is a heavy duty system compatible for use on ES boilers.

If the boiler was sealed then it would not give a true reading to both the pressure gauge and the pressure switch. For example when the boiler is filling with water for the first time it allows air to escape.

If there is pressure difference of 0.25 kg/cm2 between 1st stage and steam condenser then the U loop height should be 2.5 meter. So it is very must to seal the U seal (filling DM water in loop) before pulling vacuum.
