What is the main advantage of a float and thermostatic trap over an ordinary float trap?

The main advantage of a float and thermostatic trap over an ordinary float trap is its greater air handling ability with variable flow. This type of trap is designed to effectively manage the discharge of condensate while allowing for the escape of air and non-condensable gases. The inclusion of a thermostat in the float and thermostatic trap facilitates a more efficient balance of steam and condensate handling, which is particularly beneficial in systems that experience varying load conditions. As the flow of steam varies, the trap can adjust to allow ample air removal without negatively impacting condensate drainage.

This capability is essential in maintaining system efficiency, as it ensures that there is minimal risk of air binding in the system, which can diminish heating efficiency and lead to operational issues. The ability to effectively handle variable flows also means that the trap can maintain optimal performance under different operational conditions, making it a more versatile solution compared to an ordinary float trap, which may not perform as effectively in such situations.
