Thermodynamic Steam Trap operates on the basis of the Bernoulli principle, depending on the relationship between the velocity and the pressure exerted by the condensate and steam inside the steam trap.
They have only one moving part – the disc.
Due to their compact design and cost effectiveness, thermodynamic steam trap is widely used in applications where the condensate must be removed immediately from steam lines and steam equipment. They discharge he condensate near the saturation temperature. The traps may operate up to 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. Thermodynamic steam trap discharges the condensate intermittently.
In general, maintenance of a thermodynamic steam trap is easy as the only moving part is the disc. It can be easily replaced by removing the top cap.
