Description
The Xylem-Bell & Gossett 1BN346LF Diaphragm Expansion Tank PTA-5 is a pressure-controlling element that absorbs thermal expansion in closed-loop fluid systems. It regulates the volume change of systems such as hydronic heating, and chilled water loops in HVAC systems and assist to maintain a consistent pressure level. It works by separating air and water using an internal diaphragm that allows the expansion to occur without pressure spikes. It is connected to the piping setup at a particular point, and prevents pressure variations and secure system components.
