Precision Air Condition MDC in Seri Kembangan

Product Introduction

The cooling system occupies a very important position in the MDC system. In response to the characteristics and needs of the MDC, Kotohira has carefully created an innovative and energy-saving GentleAir series, which covers rack-mounted precision air conditioners and in row precision air conditioners. This series is suitable for modular data centers and form modular solutions

◆ Adopt EC fans and dynamically adjust air volume

◆ The flat air outlet can be installed in any U position inside the cabinet.

In row air conditioners features

Dynamic energy-saving

◆EC fan with stepless speed regulation automatically match the air volume demand of the server

◆ Inverter compressor, cooling output automatically matches server thermal load changes

◆ Outdoor fan is driven by variable frequency stepless speed regulation, the wind speed is automatically adapted to the change of ambient temperature

◆ Electronic expansion valve control, automatically matching server thermal load changes

◆ The air supply temperature control function ensures that the server air intake temperature meets the design range, which is safe, reliable, energy-saving and environmentally friendly.

◆ Standard configuration includes 1 supply air temperature sensor and 1 return air temperature and humidity sensor, and 16 external temperature sensors are optional.

◆ 37℃ return air temperature, 100% sensible heat rate design, energy saving and environmental protection.
