On demand: Sizing Expansion Tanks

April 30, 2026 | From 2-3PM ET

In this session, Xylem will aim to summarize the following for attendees:

• Discuss total system water volume and expected temperature ranges and how these parameters influence tank sizing
• Define system operating pressure parameters and correlation to cold static fill pressure, maximum operating pressure, and the relief-valve setting
• Explain how to evaluate proper pre-charge pressure and acceptance volume to determine how effectively the tank absorbs expansion, reducing cycling stress and extending system component lifespans
