Buffer Tanks

Chilled Water Buffer Tanks

Designed for chilled water systems with insufficient water volume capacity, in relation to the chiller capacity. Relatively low water volume systems require additional “buffer” capacity for the system to eliminate problems such as excessive chiller cycling, poor temperature control, and erratic system operation. The properly sized American Wheatley CBT tank adds the necessary volume to “buffer” the system.

Hot Water Buffer Tanks

American Wheatley HS Series Hot water buffer tanks are designed to operate with modern high efficiency low-mass modular boiler systems. The American Wheatley hot water buffer tank ensures minimal ΔT and provides the necessary thermal storage to prevent short cycling that could occur during low load conditions.


Prevents flow in one circuit from interfering with flow from another circuit

Eliminates the need for a primary loop circulating pump, air separator, and strainer, thereby reducing initial cost as well as operating cost

Eliminates complicated piping, reduces labor and piping costs

Sized for no more than 4 fps, low velocity in the vessel results in low pressure drops

Correctly installed hydraulic separation allows the use of multiple circulators to operate independently without interfering with each other

Ideal for multiple load systems

American Wheatley manufactures ASME hydraulic separators in standard sizes 40 gallon through 400 gallon with connections, 2" through 16"

Custom sizes readily available
