1. Single Pump Tank Set:
Single pump tank set 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.

2. Dual Pump tank set is the most common type and has 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.
