Solution & outcome

Grundfos has redefined the control capabilities of the customer’s cooling tower. Cooling system operations are now stable and controlled by differential temperature. This has resulted in significant OPEX reductions of 22%.

Easy operation

Grundfos iSOLUTIONS ensures pump operations always match system loads, resulting in maximum efficiency and minimum energy use. Our controls and integrated frequency converters ensure increased system intelligence, flexibil-ity, and the lowest life-cycle costs.

Full control

With Grundfos iSOLUTIONS, the new system adapts the speed according to
the return temperature measured by the sensor. The complete system has a
variable flow, which enables maximum savings and improved uptime.

Maximized reliability

Applying pump audits and continuous improvement techniques, Grundfos
revised the system design to raise the quality of the final package well beyond
the originally specified requirements.
