Tips for Preventing Freezing of Steam Traps
Proper selection and installation of steam traps can prevent freezing as long as there is steam passing through. However, if the steam supply is interrupted, the condensate in the heat exchanger or tracing pipe will create a vacuum, which will prevent the condensate from freely draining from the system before freezing occurs. Therefore, a vacuum breaker should be installed between the equipment to be drained and the steam trap. If the condensate is not drained by gravity from the steam
