Thermal Diaphragm Tanks

The diaphragm tank has been developed to allow the systems air cushion to be separated from the systems water. No waterlogging of the tank can occur as the air is held between the tank wall and the outside of a diaphragm placed inside the tank, while the system water is contained inside the diaphragm. This changes the system to an air elimination system, as any air extracted from the system water is passed out of the system into the atmosphere.

The diaphragm cannot be replaced if the tank fails. The advantage of this style is the initial cost. On smaller tanks the cost of replacing the bladder may exceed the cost of replacing the tank.

TTA Series (ASME)

TTA Series tanks actually are non-ASME diaphragm tank that is placed in an ASME tank. The diaphragm cannot expand any larger than the inner tank that contains it. This is why the acceptance volume of the TTA tanks is less than the total tank volume.

• Generally less costly than the comparable TXA tank.
• Heavy-duty fixed Butyl diaphragm
• Sizes range from 3 to 90 gallons

TTA-Rx (ASME) – Antimicrobial Silver

• Heavy-duty fixed Butyl diaphragm
• Antimicrobial silver plating internal

TTA-Rx-FF (ASME) – Antimicrobial Silver

• Full-Flow through design
• Heavy-duty fixed Butyl diaphragm
• Antimicrobial silver plating internal

T Series (Non-ASME)

T Series thermal expansion tanks:

• Heavy-duty fixed Butyl diaphragm
• Sizes range from 2 to 132 gallons
