What's special about these water-cooled server racks?

  • Provides 36U of rack space to house and protect your server or other network components
  • Runs cooled water from your facility throughout the rack to keep your components at optimal operating temperature, especially high heat devices
  • Closed loop design recycles hot air to prevent it from affecting the external climate control
  • If the internal temperature exceeds user-defined optimal settings, an alarm is sent and the doors automatically open so the server can be cooled by the room's cooling system, greatly reducing the chance of heat-related equipment failure

airflow diagram for Closed-Loop Water-Cooled enclosure
  1. Chilled water arrives at the enclosure from a viable source or via a coolant distribution unit (CDU) to enter the heat exchanger
  2. Conditioned air at consistent pressure is directed through a plenum chamber
  3. Conditioned air passes through rack mounted equipment
  4. Quiet (65 dB) high efficiency variable speed exhaust fans remove hot air
  5. Hot air passes across the heat exchanger
  6. Water then leaves the heat exchanger coil to begin a return trip to the chiller or the CDU
