Modular Closed Loop

The Modular Closed Loop architecture offers the ability to achieve up to 36 kW per rack of cooling power in one specific assembly. This type of architecture can be especially useful when planning to install a few very high power racks into a facility as the racks do not release any heat out into the data center environment. It is also an ideal solution when rack space is limited (for example, in an atypical server room of a mid-size company) and when the cooling becomes an issue because of high density applications housed there.



The module can consist of a virtually unlimited number of racks and CoolTeg cooling units. We recommend 6 racks (252 - 288U) as a limit where standard data center layout should applied. Both cooling unit versions, chilled water (CW) as well as direct expansion (DX), are available to provide the module with needed cooling power up to 34 kW per rack. Cooling units are connected to the coolant piping through the bottom frame. A top connection is available as an option. The dimensions of every cooling units are 300 mm width, 1200 mm depth, 42, 45 or 48U height.


The modular architecture is pre-designed for 1200 mm deep, 600 or  800 mm wide and 42, 45 or 48U high RSF racks and for 1200 mm deep, 300 mm wide and 42, 45 or 48U high side mount cooling units. The module can consist of a virtually unlimited number of RSF racks and cooling units. 6 racks (252 - 288U) could be understood as a limit where the application of standard data center layout should be considered. The configuration of the rack differs according to its position in the module - please be aware of it when planning the module. All racks are delivered fully assembled with the necessary passive airflow management installed. The Modular Side Closed Loop can be configured according to the needs of any individual customer and can be modified and completed with additional racks and cooling units, as required in the future.
