Multi Density Cooling

Mitsubishi Electric I-NEXT I.T Cooling

Mitsubishi Electric’s new Multi Density systems combine the efficiency, quality and simplicity of VRF with high performance close coupled air conditioning units.

The range is particularly suitable for high density racks and blade server cooling in data centres. It is able to cope with the high density of the thermal load, putting the air conditioning unit directly within the rows of racks to cool the localised heat sources (hot spots).

 

Multi Density is ideal for applications where high sensible cooling and close control of temperature
in high density applications is required. This system consists of multiple indoor ‘coolside’ close coupled
air conditioners connected to a City Multi VRF outdoor unit. The result is a full inverter multi-split
system, designed according to the best quality standards and dedicated to the most reliable I.T. environments.

Key Features

  • High Efficiency – full Mitsubishi Electric
