Thermodynamic Steam Trap

South American Valve is the top most Thermodynamic Steam Trap Supplier in Chile.  A thermodynamic steam trap is a type of steam trap used in steam systems to remove condensate and prevent the escape of steam. It operates based on the principle of thermodynamics and utilizes the difference in pressure between steam and condensate to function. Thermodynamic steam traps operate using the principle of the Bernoulli equation, which states that as the velocity of a fluid increases, its pressure decreases. The trap consists of a disc or valve that opens and closes based on the difference in pressure between steam and condensate.

When steam enters the trap, the pressure on the upstream side of the disc increases, causing it to lift or open. This allows the steam to pass through the trap and continue along the system. As condensate forms and flows into the trap, the pressure on the downstream side of the disc increases, forcing the disc to close and prevent the escape of steam.

South American Valve is the top most Thermodynamic Steam Trap Supplier in Chile. It’s worth noting that while thermodynamic steam traps have their advantages, there are other types of steam traps available, such as mechanical, float and thermostatic, and inverted bucket traps. The choice of steam trap depends on the specific requirements of the steam system and the characteristics of the condensate being handled.

  • Compact Size: Thermodynamic steam traps are typically small in size, allowing for easy installation in tight spaces. Their compact design makes them suitable for applications with space constraints or limited installation options.
  • Simple and Robust Construction: Thermodynamic steam traps have a relatively simple design with fewer moving parts compared to other types of steam traps. This simplicity contributes to their durability and reliability. With fewer components, there are fewer chances of mechanical failure or breakdown.
  • High Resistance to Water Hammer: Thermodynamic steam traps are known for their ability to handle water hammer effectively. Water hammer is a phenomenon that occurs when steam and condensate mix rapidly, causing pressure surges. The design of thermodynamic traps helps dissipate the energy associated with water hammer, preventing damage to the trap or the system.
  • Wide Operating Range: Thermodynamic steam traps can operate over a wide range of pressures and temperatures. They are capable of handling high-pressure steam applications and can withstand high temperatures without compromising their performance.
  • Rapid Response Time: Thermodynamic steam traps have a fast response time, quickly opening and closing in response to pressure changes. This ensures efficient removal of condensate and minimizes steam loss, leading to energy savings.
  • Self-Modulating Operation: Thermodynamic steam traps are self-modulating, meaning they automatically adjust their opening and closing based on the steam and condensate flow conditions. This self-regulating nature allows them to handle varying loads without the need for manual adjustment.
  • Low Maintenance Requirements: Thermodynamic steam traps have minimal maintenance requirements due to their simple design and robust construction. They do not require regular maintenance or adjustment, reducing downtime and maintenance costs.
  • Cost-Effective Solution: Thermodynamic steam traps are generally cost-effective compared to other types of steam traps. Their lower initial cost, combined with their long service life and low maintenance requirements, results in overall cost savings throughout the life of the steam system.


  • Steam Distribution Systems: Thermodynamic steam traps are commonly used in steam distribution systems to remove condensate and ensure the efficient flow of steam to heat exchangers, process equipment, and other steam consumers. They help maintain optimal heat transfer and prevent damage caused by water hammer.
  • Process Equipment: Thermodynamic steam traps are employed in various process equipment, such as steam jacketed vessels, heat exchangers, and sterilizers. These traps effectively drain condensate from the equipment, ensuring consistent and efficient operation.
  • Tracing Lines: Tracing lines are used to maintain desired temperatures in pipelines, tanks, and other equipment. Thermodynamic steam traps are ideal for these applications as they can remove condensate effectively from the tracing lines and maintain the desired temperature levels.
  • Petrochemical and Refining: Thermodynamic steam traps find extensive use in the petrochemical and refining industry. They are employed in applications such as steam tracing, steam injection, and steam distribution for various processes, including distillation, cracking, and reforming.
  • HVAC Systems: Thermodynamic steam traps are utilized in HVAC (Heating, Ventilation, and Air Conditioning) systems that use steam for heating or humidification purposes. They help remove condensate from the steam distribution lines, ensuring efficient heat transfer and maintaining the desired indoor climate.
