The BTCS Series is a thermostatic steam trap designed specifically for use in clean steam systems demanding that sanitary conditions be maintained. It features a 20 Ra internal finish, and a self-draining design to minimize the possibility of medium entrapment and bacterial growth.

The improved configuration of the BTCS Series has been specifically designed to provide higher flow rates at lower pressures and low subcooling levels. In lab testing, it has exhibited excelled flow rates at subcooling levels of only 5°F (28°C)
