SERIES S

Thermodynamic disc steam traps discharge the condensate near the saturation temperature. The traps may operate until a back pressure of 80% of the inlet pressure, but for smooth operation it is recommended that the back pressure does not exceed 50% of the inlet pressure.

Applications:


steam main drips, heat exchangers and all other applications in the petrochemical, food, textile, pharmaceutical and other industries where the condensate must be removed quickly.
