Multi Density Cooling
Mitsubishi Electric I-NEXT I.T Cooling
Enquire Now
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.

Notes: THE COOLING CAPACITY DOES NOT CONSIDER THE SUPPLY FAN MOTOR THERMAL LOAD. *1 All data are refers to the Rating Configuration with 2x m-MROW-Z G02 F/S 025 @35°C Outdoor Temperature and 35°C/27%rh
Indoor Temperature. *2 SHR = Sensible cooling capacity / Total cooling capacity. *3 Corresponding to the nominal ESP=20Pa. *4 Sound pressure level on air return at 1m. *5 Rubber pipe – refers to internal diameter. *6 Minimum section.
It’s possible to connect indoor units with a sum of sizing from 25 to 75. These units contain <HFC R410A [GWP100 2088]> fluorinated greenhouse gas. *7 When outdoor unit is below indoor unit.
