Thermodynamic steam traps are rugged, simple devices used to remove condensate and a small amount of air from steam systems. They operate using a disc that responds to changes in steam velocity and pressure, making them reliable for drip service on steam mains, supply lines, and high pressure applications.

These traps are especially suited for outdoor installations, freeze-prone environments, and superheated steam service due to their simple design and minimal moving parts. Models with integral strainers and blowdown valves offer added protection from contamination and ease of maintenance.

While thermostatic traps generally offer superior air handling, thermodynamic traps excel in drip, distribution, and high pressure steam line applications where simplicity, durability, and wide operating ranges are priorities.

When selecting a thermodynamic trap, consider system pressure, temperature limits, connection type, and whether features like integral strainers or blowdown valves are needed to match your steam system requirements.
