Bimetallic steam traps

Bimetallic steam traps discharge condensate below saturation temperature, allowing some sensible heat in the condensate to be recovered. This makes them well suited to duties where subcooling is acceptable or beneficial. They are among the most robust thermostatic steam trap designs and withstand waterhammer and corrosive condensate well. The range covers a broad span of pressures and loads, offers good air venting, reduces flash steam losses and uses dedicated bimetallic element designs to suit different capacities. They are commonly considered where durability and condensate cooling are more valuable than immediate continuous drainage at steam temperature. They are also relevant in higher-pressure duties where a tougher thermostatic mechanism is preferred over lighter-duty alternatives.
