Wall-mounted cooling unit
Compact rack cooling for high heat loads

This cooling unit is mounted on the side wall of the rack and is ideally suited to small IT rooms or industrial cabinet systems. Depending on requirements and conditions, either cold water or coolant is used for cooling.

 

For coolant-based cooling, the warm server exhaust air in the rack is cooled via a coolant cycle. The heat is dissipated to the ambient air in the installation room. Depending on the room’s design, a room cooling concept must be provided for.
 

With the aid of cold water, the warm server exhaust air is guided to the outside, ensuring the rack is cooled on the inside.

FAQ Wall-mounted cooling unit
What performance range can be covered with wall-mounted cooling units?

The wall-mounted cooling units (“DX” type with coolant) can cover a performance range between 0.75 kW and 2.5 kW.

Is it necessary to have a condensation line for a wall-mounted cooling unit?

That depends on the type of cooling. Wall-mounted cooling units using coolant (DX) have integrated condensate evaporation. There is no need for a condensation line on site.
Wall-mounted cooling units using have a ½ inch hose nozzle on the underside which can be connected to an on-site condensation line.

What does “L35/L35” mean?

“L35/L35” means that at an ambient temperature of 35 °C and a required temperature of 35°C inside the rack, a cooling capacity of 0.75 kW is achieved.

What needs to be considered when installing racks with wall-mounted cooling units?

Cooling units operating with coolant transfer the heat load from the rack to the installation room. This is increased additionally by the electrical waste heat from the compression cooling process. The entire heat load should therefore be dissipated by a suitable room cooling system.
For this, especially in the close proximity of offices, the details on sound emissions contained in the data sheet must be taken into account.

Does a wall-mounted cooling unit have any influence on the rack’s protection rating?

The cabinet’s protection rating, either IP20 or IP54, remains unaffected by the use of a cooling unit.
