A steam trap is fundamentally a device designed to remove condensate, air, and other non-condensable gases from steam systems while preventing the escape of steam. Its primary function is to ensure that the steam remains effective and efficient by allowing collected condensate, which results from the cooling and condensing of steam, to be drained away. This removal of condensate helps to maintain the efficiency of the steam system, as excess water can lead to reduced performance, increased energy consumption, and potential equipment damage.

In the context of steam systems, it is crucial to manage condensate effectively to maintain the desired pressure and thermal characteristics. By keeping the system free of unwanted condensate and ensuring smooth operation, steam traps play a key role in the overall functionality and reliability of steam heating applications. The importance of effective condensate removal cannot be overstated, as it directly relates to the overall operational efficiency of the system.
