CA and CX Series Expansion Tanks



These Taco tanks are designed to solve a long-time problem in the hydronics industry. In old style, plain steel tanks, the direct air-to-water interface can allow the air to be absorbed into solution and carried to other parts of the system. The results can be waterlogged tanks, air-bound terminal units, excessive corrosion, inefficient balancing and pump cavitations.

Not so with Taco CA Series Tanks. In this design, the air is held captive on the shell side, with all expanded fluid directed into the bladder (in CA models) or the diaphragm chamber (in the CX Series). Air and water are permanently separated, so no absorption can take place during the system cycle.

Properly sized, selected and located air separation and removal components can provide a stable, tight and closed hydronic system. In most properly-sized “CA” systems, you can reduce the tank size by 80% compared to the old style, plain steel tanks.

CA Series Tank features include:

  • Heavy-Duty Butyl Rubber Bladder, Removable for Inspection
  • “Full Acceptance” Vessel
  • Shell: Fabricated Steel, Designed and Constructed per ASME Section VIII Div. 1
  • Standard Bladder: 125 PSIG (862 kPa)
  • Optional Bladder: 150 PSIG (1,034 kPa)/250 psig (1,723 kPa)
    CX Series Tank features include:
    • Heavy-Duty Butyl Rubber Diaphragm
    • “Limited Acceptance” Design—For small heating installations and most chilled water applications where smaller air volumes and expanded fluid volumes are needed.
    • Shell: Fabricated Steel, Designed and Constructed per ASME Section VIII Div. 1
    • Standard Diaphragm: 125 PSIG (862 kPa)

    Please Note:

    CAX Series Tanks have been superseded by Taco CBX Tanks.
