ASME EXPANSION TANK, 5 GALLONS

The WTTA-12 12in x 14in ASME Thermal Expansion Tank is used on hot water systems for protection against thermal expansion. All WTTA Tank Models are ASME fixed bladder type, ideal for both commercial and industrial applications. As the system pressure increases from thermal expansion, water enters the bladder of the tank, expanding into the pre-charge air chamber to keep the system pressure below the relief valve setting. Materials include a carbon steel outer shell, stainless steel system connection, and FDA approved butyl rubber bladder. The WTTA conforms to all lead-free requirements and can be used on drinking water systems.

• Bladder style tank design is ideal for ASME approved installations
• Extra heavy steel shell keeps system pressure below the relief valve setting
• Protects drinking water and hot water systems from thermal expansion
• Stainless steel system connection protects against corrosion
• ASME Section VIII
