1. Multiple Chiller Pump Tank Sets: Multiple chiller pump tank sets can be used where the process water flow is constant and the flow is the same as the chiller.
Not recommended for cooling towers in a cold climate where the cooling tower can freeze.
Dual Pump Tank Sets are the most common type of tank set with two pumps. One pump is dedicated to the cooling towers or chillers to maintain constant flow required by them to ensure maximum efficiency and safe operation.
The second pump is dedicated to the process to supply higher flows than the cooling tower or chillers would normally allow, and higher water pressure required by the varying process equipment demand.
