  • Further Details

  • Supports five times the computing power of air-cooled facilities.
  • Saves on energy bills. Reduces energy consumption of indoor cooling units by 90% or more!
  • Neutralizes heat at the source, returning cooled air into the data center and providing up to 35 kW of cooling.
  • Eliminates the need for hot-aisle/cold-aisle configurations—place your computing equipment where you want it.

  • Nothing cools like chilled water. Now you can harness the cooling power of liquid in your data center with Cold Front. Cold Front is the perfect solution for tightly packed server rooms or high-density enclosures. It works to sensibly cool a data center enclosure and lowers the total cost of ownership because it reduces both energy and space requirements.

    The average operating cost of data centers has grown three times faster than capital investment in new IT equipment. Factors for uncontrolled costs include cooling, equipment capital expense, inefficient designs, high installation costs, rising energy bills, and ongoing maintenance. So, how can you add value while meeting your cooling challenges?

    In typical data center installations, the infrastructure required to support perimeter or in-row cooling must be built in on Day One. Because the Cold Front solution can be installed quickly and easily and requires no pressurized raised floors, air plenums, exhaust chimneys, etc., you can build as you grow. Cold Front enables you to add units as you add computing, so you don't pay for infrastructure that you don't need.

    The Cold Front cooling solution uses Heat-Transfer Doors in a closed-loop circulatory system with a Coolant Management System that monitors the temperature and pressure conditions, increasing and decreasing flow as conditions change in the data center. This approach offers data centers consistent and scalable cooling to meet their changing demands.

    Heat-Transfer Door
    The Heat-Transfer Door neutralizes heat at the source. Chilled liquid passing through the door cools the exhaust air before it re-enters the data center. The passive design has no moving parts for efficiency and reliability. It requires no fans or electricity because it uses the server fans to move the hot air through the door. The door uses a closed-loop circulatory system, and its specially designed perforations and coil maintain airflow through the cabinet. The Heat-Transfer Door replaces the existing rear door and is compatible with any manufacturer's cabinets.

    Use the door with our Coolant Management System (CFCMS20KW208, CFCMS20KW230, CFCMS260KW208, CFCMS260KW480) for consistent data center cooling that grows as your computing capacity increases.
