Thermodynamic Traps

Thermodynamic Steam Traps

Unlike Float and Inverted bucket traps, thermodynamic traps do not rely on density difference between steam and condensate to function. Instead, they utilize the dynamics of flash steam and water to control the moving parts necessary to maintain steam flow and eliminate condensate. Thermodynamic traps come in several types that all utilize the same principle: Disc, Impulse, and Labyrinth.

While the fixed orifice steam trap qualifies as a thermodynamic trap, their lack of flexibility and sensitivity to clogging caused by dirt can hamper performance and are thus not recommended for use.

Each type has its individual strengths which makes it relatively easy to locate a suitable trap for different needs. On average, thermodynamic traps are significantly smaller than their mechanical counterparts and are able to handle a large amount of condensate relative to their size. They are a good solution for applications that have space at a premium.

Here are some things to take into account when looking into the benefits and disadvantages of switching to a thermodynamic trap.


Disc Trap Advantages

  • They have excellent resistance to heat and are not likely to suffer damage due to freezing temperatures.
  • They are not affected by vibration or water hammer, minimizing damage to the trap itself over time.
  • As there is only a single moving part in a disc trap, it is easy to maintain and does not require removal from the line.


Impulse Trap Advantages

  • The ability to work with a wide range of steam pressures, including superheated steam and high pressure scenarios, without necessitating any changes in valve size.
  • Excellent ability to vent air, thus limiting the occurence of air-binding.


Labyrinth Trap Advantages

  • Very little possibility of mechanical failure due to a lack of automatic parts utilized in the system.
