Structure and Feature

Thermodynamic Steam Trap:

Thermodynamic steam traps have a unique operating principle which relies on the dynamics of water and flash steam. They are simple, robust and reliable and can operate up to very high temperatures and pressures.

Advantages of the thermodynamic steam trap:

1. Thermodynamic traps can operate across their entire working range without any adjustment or change of internals.

2. They are compact, simple, lightweight and have a large condensate capacity for their size.

3. Thermodynamic traps can be used on high pressure and superheated steam and are not affected by waterhammer or vibration. The all stainless steel construction offers a high degree of resistance to corrosive condensate.

4. Thermodynamic traps are not damaged by freezing and are unlikely to freeze if installed with the disc in a vertical plane and discharging freely to atmosphere. However, operation in this position may result in wear of the disc edge.

5. As the disc is the only moving part, maintenance can easily be carried out without removing the trap from the line.

6. The audible 'click' which occurs as the trap opens and closes makes trap testing very straight forward.
