STEAM TRAPS Introduction Steam Trap Selection Guidelines • Typical Applications

Steam Separator Separators are used on steam mains and steam supply lines to remove entrained water in the steam. Steam flows through the Separator and the condensate falls by gravity to the bottom where it needs to be discharged through a steam trap. F&T traps are recommended for this application.

Heat Exchanger (Steam Coil)

Storage Tank Coil When heating Storage tanks, the heat exchanger may be placed inside the tank. This may be simpler and less expensive than using a pump to circulate the product thru an external heat exchanger. Shown is a WT4000 Series thermostatic process trap removing the condensate. If a small amount of sub-cooled condensate is backed up, it will not adversely affect the process.

Platens Platens are extensively used in the molding industry when steam is required to heat the mold, allowing plastics and rubber to be formed into different shapes and sizes. On this particular Process application, a TD700S thermodynamic trap is being used to remove the condensate. Since Air is generally only present during system start-up, and this type of process may run non-stop for extended periods of time, a thermodynamic trap is a potential choice for this application.
