CoolSpot CW WW—Cooling At The IT Rack Level | CONTEG

CoolSpot CW WW

Small air-conditioning unit in Wall Mount design for double power or better safety thanks to the standby unit.

The CoolSpot Wall Mount (AC-WW) solution is available in the nominal cooling capacities from 870 W to 6700 W (cooling capacity depends on the water and air temperature and water flow). Since the CoolSpot AC-WW cooling units are installed instead of one of the rack side panels, there is no limitation by the overhead clearance.

These CoolSpot AC-WW cooling units are compatible with the free-standing racks series RDFRSF. It is ready for projects where insufficient clearance exists to install a Top Mount solution and where cold water is present. Hot air is sucked from the top of the rack, and the cold air is delivered to the bottom. The advantage of this Wall Mount model is the possibility to connect two CoolSpot AC-WW cooling units to one rack. It can ensure the demanded redundancy of the cold sources.

  • All heat load is transferred to the water out of the room
  • Operation in unlimited room temperature
  • No filters required 

CoolSpot CW was developed for places where heat and noise from the compressor could be disturbing in the room. It demands connection to the chilled water piping system of the building. The cooling capacity of the air-conditioning unit is controlled by a 2-way valve inside to keep the set temperature in the CONTEG cabinet.

CONTEG CoolSpot CW units are designed to keep the right environment inside Conteg cabinets. The inside temperature of the rack equipped by the CoolSpot unit is controlled with very low energy consumption. The CW series is ready for connection to the chilled water piping system in the building. The radial fan in the air-conditioning unit cares for the right airflow through a high-capacity water-air heat exchanger to the rack.

CoolSpot CW can be installed in rooms with the continuous presence of people, thanks to low noise and no heat load coming out of the unit. When installing these units into closed areas always make sure that the room has sufficient space above or aside the cabinet. The CoolSpot CW includes a 2-way solenoid valve with a gas-loaded mechanical thermostat at return air. The temperature Setpoint can be adjusted with a screwdriver from 20 to 46 °C. The cooling band is 4 K. If a high condensate level is detected, it closes the solenoid valve while fans keep running.

CoolSpot cooling units are easily integrated with monitoring system RAMOS to provide remote notification about the temperature inside the rack.
