Chilled Water Buffer Tanks

Envirosep Chilled Water Buffer Tanks (envirosep model CWBT) are designed for chilled water systems with insufficient water volume capacity, in relation to the chiller capacity. Relatively low water volume systems needs additional “buffer” capacity for the system to eliminate problems such as excessive chiller cycling, poor temperature control and erratic system operation. The properly sized envirosep CWBT adds the necessary volume to “buffer” the system volume.

Envirosep buffer tanks, featuring the Flush-mountTank™ design, allows for optimal temperature control in a closed loop chilled water system. The standard internal baffle increases water mixing and aids in separation of air which can be released from the top vent.
