This non-potable water expansion tank is for commercial and residential closed-loop hydronic heating systems. It helps accommodate hot-water thermal expansion and supports system pressure management below the relief valve setting.

The 6-gallon carbon steel tank has an epoxy finish and is pre-charged to 12 psi. Its expansion membrane and butyl diaphragm separate water from air within the tank. It connects to supply piping with a 1/2 in. MNPT connection and includes a 0.302-32 charging valve connection for on-site charging. Maximum working pressure is 75 psi (5.3 bar).

Key Features:

  • 6-Gallon Capacity: Provides expansion volume for closed-loop hydronic heating piping.
  • 12 PSI Pre-Charge: Supplies an initial tank charge for system setup.
  • Membrane and Butyl Diaphragm: Keeps water separate from tank air and helps minimize air-charge loss.
  • 1/2 in. MNPT Connection: Connects directly to compatible supply piping.
  • Charging Valve Connection: Allows on-site tank charging to meet system requirements.
  • 75 PSI Maximum Working Pressure: Supports systems operating within the stated pressure limit.

Choose this 6-gallon tank for compatible non-potable, closed-loop hydronic heating applications requiring thermal expansion control and on-site charging capability.
