s-MEXT IT Cooling

High Capacity into a compact footprint

The indoor s-MEXT air conditioner matches the highest efficiency levels with the industry’s most compact footprint, thanks to the split design. [Findings based on market research conducted by Mitsubishi Electric Australia (March 2022)]
Its small size design means it can easily integrate into small IT rooms or existing environments without sacrificing any kW per square metre.

Pinpoint accurate temperature and relative humidity control

s-MEXT controls temperature and relative humidity with pinpoint accuracy, even in the case of very strong thermal variations. The system has been engineered to deliver top-class efficiency values, the indoor unit features premium quality components: EC plug fans, evaporating coil with hydrophilic treatment, electrical panel, and PID microprocessor control system.

Manage return air temperatures up to 35°C

Increased power densities in IT environments have led to growing temperatures (up to 23°C) of intake airflows directed to the IT equipment (ASHRAE ‘Thermal Guidelines for Data Processing Environments’).
The s-MEXT and Mr Slim cooling package has been designed to manage return air temperatures up to 35°C, matching the requirements of the most critical data centres (up to 52°C outdoor air temperature).

High-efficiency targets

Air conditioning and cooling systems account for about 40% of total electricity usage in data centres. An efficient cooling strategy may assist your company in improving energy efficiency, which could result in significant cost savings.

Both the s-MEXT and Mr Slim units feature best-in-class components to reduce power consumption and advanced logic to control the whole cooling system efficiently.

Two types of air supply

Under Bottom Air Supply & Top Air Return installation option is suitable for rooms with raised floors. Over Top Air Supply & Frontal Air Return installation option ‘over’ is suitable for rooms with standard floors.

R32 refrigerant

s-MEXT close controls air conditioner is available in R32 refrigerant. R32 enables increased energy efficiency compared to R410A, with just one-third of the global warming potential of R410A.

New Generation Inverter EC Fans

High-performing EC fans are made of polymeric ultralight material and help improve airflow modulation at partial loads. The fans deliver significant advantages in terms of reducing noise levels by 4-5 dB(A) compared to traditional* solutions and reducing the absorbed power by 25% compared to traditional* solutions. *Traditional is a non-inverter system/fixed speed compressor (EC fans compared to AC fans).

Fast Installation & Easy Maintenance

The constructive features and the internal layout guarantee faster installation, and the frontal access to the main components makes routine inspections easier.

EVOLUTION+ Advanced Unit Control

The electronic heart of the unit is the EVOLUTION+ controller. Designed internally to manage all the unit’s variables perfectly, it features evolved characteristics to make the unit totally configurable:
• Automatic reactivation after a black-out
• Serial cards for BMS interfacing
• BLACK BOX for preventive analyses
• Up to 100 events recorded
• Non-volatile ‘flash’ memory for data storage
• Display with easy-to-read graphic icons
