Bolt-On Flexibility
The innovative construction of the Marley OlympusMAX allows for the recirculating adiabatic pre-cooling system to be installed in the field, providing more flexibility on cooling capacity. This option allows for applications initially specified as dry to be converted to adiabatic later by using an easy-to-install bolt-on kit as cooling demand increases.

Optimized Adiabatic Design
The OlympusMAX recirculating design collects and reuses water in the adiabatic system, decoupling water distribution from water usage. The design allows users to dial in water capacity by cell to further optimize usage.
Efficient Water Delivery
Higher flow rates typically associated with recirculation systems help limit dry spots and ensure uniform wetting of the pad, maximizing efficiency and lengthening pad life. Recirculating systems also limit total water usage; once-through or spray systems typically run lower flow rates or risk excessive water use.
Unique Recirculation System Design
Traditional designs pull from a mixture of blowdown and makeup water, but Marley’s adiabatic design segregates the two streams to minimize wasteful discharge of cleaner water and ensure the most concentrated stream is rejected.
