Taco CA Expansion Tanks

Feature Overview: Taco CA Expansion Tank

National Pump Supply is a mark of quality and assurance. We bring to you the latest and the most advanced solutions, ensuring complete effectiveness and efficiency. The Taco CA Expansion Tank are full acceptance captive air expansion tanks that provide the required separation between the air and water. It is one of the best in it’s range and is touted to be the most durable, tough and bladder expansion tank which is currently the longest lasting effectiveness. Another great feature is that the Taco expansion tank is available in multiple sizes to suit individual needs and requirements.

Benefits of the Taco CA Expansion Tank:

  • -It completely eliminates any problems with the flow of water
  • -It negates the problem of water logged expansion tanks
  • -It does not corrode and thus removes the issue of expansion tanks corrosion
  • -It removes the burst bladder problem

The shell has been fabricates using the most advances steel design and has been constructed keeping in mind the need for 100% quality. The bladder us field removable, adding to the ease of use and functionality. Since the tank and water do not come in direct contact the problem of corrosion.

The taco expansion tanks have become one of the best for many reasons, most notably because they dramatically reduce the many gallons of water required to compress atmospheric pressure air in an air cushion plain steel tank to fill pressure. This allows for reduction in captive air expansion tank size of up to 80% compared to air cushion plain steel 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.

Multi-Purpose Solution:

Multi-story buildings:

If the system pressure is not maintained above atmospheric at the top of the building then not only will air come out of solution, but air can actually be drawn into the system. This will result in loss of system performance with areas of low and no flow in this portion of the system.

High-Rise buildings:

Often the expansion tank, air separator and fill valve are located at lower levels of the building. At upper levels air will come out of solution as the pressure decreases. This is similar to what divers experience as the “bends”. One solution, which designers and maintenance personnel learned over time, was to “over pump” the system through high pump heads. This increased the pressure at upper levels of the building and forced air back into the system.

For pumps located at upper levels of the building this is even more problematic. Pumps in these locations can actually be attempting to pump air.

In a captive air tank, like the Taco CA Bladder Expansion Tank, the air is held captive by the use of a bladder or diaphragm with the expanded water being held on one side of the diaphragm or bladder and the air on the other side. This permanent separation allows the tank to be pre-charged on the air side of the bladder to the minimum operating or fill pressure. This eliminates the initial water volume needed to compress the air from atmospheric pressure to the system minimum (fill) pressure. This allows the bladder expansion tank to be charged to the fill pressure without the introduction of system fluid offering a sizable reduction in the required tank volume.

The different types of Taco expansion tanks and their application:

  • -Air Cushion Plain Steel Expansion Tank
  • Small Systems, Low Cost, Ceiling mounted to save floor space
  • -Partial Acceptance Captive Air Diaphragm Expansion Tank
  • Small Systems, Low Cost
  • -Partial Acceptance Captive Air Bladder Expansion Tank
  • Large Systems, Low Cost
  • -Full Acceptance Captive Air Bladder Expansion Tank
  • Large Systems; especially where reliability and low maintenance cost are important

The different types of Taco CA Expansion tanks each have their own unique use and functionality. Depending on specific and individual requirements, one can choose the most suitable one. Each of these have been designed keeping in mind the best results and maximum durability. The efficiency and effectiveness of residential, commercial or any other space can be greatly enhanced with an effective system such as Taco expansion tanks.

The numerous benefits and the many advantages together makes this one of the most sought after tank systems available today. National Pump Supply only offers the very best and most efficient products, that enhance to your ease and functionality. The Taco CA expansion tank is definitely one such product that will greatly add to the functionality and use of your space.
