The Motivair ChilledDoor® Rack Cooling System targets the critical cooling requirements of today’s modern server rack designs. As technology continues to advance, traditional methods of cooling racks such as CRAC/CRAH, containment, hot/cold aisles, and in-row systems have become less appealing as densities increase.

Room air is pulled into the cabinet via the ChilledDoor’s® EC fans. The room air picks up heat as it passes through the servers and then enters the ChilledDoor’s® high efficiency heat exchanger. The heat is transferred to the coolant inside the heat exchanger and sent out to the chilled water source (see exploded view example). The ChilledDoor® then exhausts cool air back to the room at a predetermined set point. The ChilledDoor® monitors the server air temperature or pressure, ambient room temperature, entering water temperature, and leaving air temperature, allowing it to actively adjust to changes at the rack level. By doing this it creates a “heat neutral” environment requiring only humidity control.

Motivair ChilledDoors® are available with 2-5 fans providing maximum scalability and flexibility for future growth. The ChilledDoor® comes in multiple models, with varying heights and sizes, including the M4, M8, M12, M12-F, M14, M14-6, M15, M15-E, and M16. Motivair has the solution to meet all of your rack cooling needs today and in the future.
