Resideo XPS-090V/U 44 Gallon Thermal Expansion Tank

Resideo XPS-090V/U XPS Series 44 Gallon Thermal Expansion Tank

The Resideo XPS-090V/U is a 44 gallon vertical thermal expansion tank designed to absorb hot water expansion in larger closed heating systems. Part of the Resideo XPS Series, this tank helps maintain proper system pressure as water expands during heating.

The XPS-090V/U features a heavy-duty butyl diaphragm that separates the air and water chambers. This clamped diaphragm design helps prevent the air and water from mixing while supporting reliable operation in closed-loop heating applications.

Designed for larger heating installations, the XPS-090V/U provides a maximum acceptance volume of 34 gallons and a maximum safe operating pressure of 100 psi.

This model features a 1-1/4 inch female NPT connection, vertical configuration, and non-ASME construction.

Thermal Expansion Control

As water is heated within a closed heating system, its volume increases. Without sufficient expansion capacity, this increase can cause system pressure to rise.

The XPS-090V/U provides space for this expanded water, helping accommodate changes in water volume and maintain appropriate pressure throughout the heating cycle.

Heavy-Duty Butyl Diaphragm

The expansion tank uses a heavy-duty butyl diaphragm to separate the water side of the tank from the air chamber.

This design allows expanding water to enter the tank while compressing the air chamber, providing the additional volume required as system temperature increases.

44 Gallon Capacity

With a total tank volume of 44 gallons (166.8 liters), the XPS-090V/U is designed for larger closed heating system applications.

The tank provides a maximum acceptance volume of 34 gallons (128.9 liters).

1-1/4 Inch Female NPT Connection

The XPS-090V/U features a 1-1/4 inch internal female NPT connection for integration into compatible heating system piping.

Proper tank sizing and installation should be determined according to system volume, operating temperatures, pressure requirements, and applicable installation requirements.

Applications

The Resideo XPS-090V/U is designed for:

• Closed heating systems

• Hydronic heating systems

• Larger heating installations

• Commercial heating applications

• Building heating systems

• Closed-loop hot water systems

• Thermal expansion control

Specifications

Important Product Information

The XPS-090V/U is intended for closed heating applications and is a non-ASME construction model.

For applications requiring ASME construction, an appropriate ASME-rated expansion tank should be selected instead.

Correct expansion tank sizing is important for system performance. Tank selection should account for system water volume, fill pressure, operating temperature, maximum allowable pressure, and other system requirements.

Why Choose the Resideo XPS-090V/U?

The Resideo XPS-090V/U provides 44 gallons of expansion tank capacity, a 34 gallon maximum acceptance volume, heavy-duty butyl diaphragm construction, 100 psi maximum operating pressure, and a 1-1/4 inch female NPT connection.

Its large capacity and vertical configuration make it a practical solution for managing thermal expansion in larger closed hydronic heating systems.
