The Sussman Separator design incorporates a water
seal at the outlet which permits the operator to
introduce cold water from the bottom to mix with
the hot water and boiler steam blowdown in the
separator. This reduces the outlet temperature to
a level that makes it safe for discharge.
Note: 1BHP is approximately 10KW.
