OptiCool Close-Coupled Cooling

Fully Integrated Close-Coupled Cooling Solution

Legrand and OptiCool Technologies® have joined forces to provide the most advanced close-coupled cooling solution on the market today, reducing in-room cooling energy up to 95%.

When combined with the built-in airflow efficiencies of the Mighty Mo® GX enclosure, this fully integrated cabinet solution offers maximum energy efficiency, capacity and redundancy, by removing the heat from the computing equipment exhaust air out the back of the cabinet.

The Legrand Mighty Mo GX Cabinet is the only approved OptiCool-Ready cabinet in the market today. Customers benefit by knowing the Cool Door System is fully compatible with and directly attaches to the Mighty Mo GX Cabinet out-of-the-box. This eliminates costly transition frames, custom engineering time, excess installation time and product ordering complexity.
