Take advantage of the most energy efficient rear door cooling solution through Rahi’s global partnership with USystems.

Introducing Rear Door Cooling

Maintaining data center temperature is critical to supporting equipment and preventing downtime. As one of the most integral parts of the data center, cooling generally requires a lot of power to run efficiently, in fact cooling represents 38% of the power consumed. With this in mind, USystems has created the most energy efficient rear door cooling system to help optimize data centers across the globe.
