Split cooling package for data centres
MITSUBISHI ELECTRIC AUSTRALIA has launched an energy efficient cooling system for IT environments.
Building on the company’s strong legacy of IT Cooling, s-MEXT is the new cooling system that delivers top class efficiency alongside premium Mitsubishi Electric quality.
The split cooling package consists of the s-MEXT high precision air conditioner indoor unit connected to a Mr Slim R32 inverter outdoor unit.
The product is monumental for data centres around the country where 40 per cent of total electricity usage comes from air conditioning.
Aside from its energy efficiency focus, the new s-MEXT air conditioning has been designed with data centres front of mind and is equipped to precisely control temperature and relative humidity.
Its small size design means it can easily integrate into small IT rooms, small data centres, or distribution rooms without sacrificing space, according to Mitsubishi Electric Australia national product manager, Atesh Mani.
“We’re really excited to launch the latest product in the Mitsubishi Electric IT Cooling family. The s-MEXT has really been manufactured to provide IT environments with powerful cooling solutions whilst providing businesses with a R32 refrigerant option,” Mani said.
Increased power densities in IT environments have led to growing temperatures (up to 23°C) of intake airflows directed to the IT equipment.
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.

“We’re very aware that a significant portion of the electricity consumed by data centres is by air conditioning as such, it is really important that we are constantly innovating to meet the highest energy efficiency standards,” Mani said.
S-MEXT is available in over (top air supply) and under (bottom air supply) variants, for a wider range of applications. The new s-MEXT is available now.
Blue skies ahead for Kelvion
TOGETHER WITH ADESSO and Microsoft, Kelvion has created a new feature in its heat exchanger configuration platform that will sig- nificantly improve performance.
Select RT supports customers in making the right product selection, according to IT Project Lead at Kelvion, Christian Sorowik.
“Kelvion Select RT is a complex digital con- figuration platform for heat exchangers in refrigeration,” he said.
“Based on different parameters such as tem- perature or fluid, when using Kelvion Select RT, the right heat exchanger can be found with just a few clicks and designed according to individ- ual operating conditions.”
Now there is an important upgrade: with the Ambient Weather function, developed by the IT service provider adesso, different weather pro- files and extreme weather conditions can now be predicted automatically.
With the “Azure” cloud solution, Microsoft has provided the technological base for this innovation.
In Kelvion Select RT, the future location of the heat exchanger plays a decisive role when select- ing and designing the product. Because the operation of a heat exchanger in the Arctic or deserts places different technical demands on the equipment - and these must be calculated in advance.
Otherwise, the efficiency of the heat exchanger can be reduced or even lead to an early breakdown.
Kelvion global sales and solutions manager, Sascha Ostermann, said the company’s cus- tomers are located in all latitudes around the world and have to anticipate different weather conditions and sometimes the weather condi- tions are extreme.
“Furthermore, new heat records are causing uncertainty as to how these extremes affect the service life of the heat exchangers,” he said.
“Thanks to the data in RT Select, a data- based purchase decision is now possible that automatically takes extreme weather conditions into account during configuration."
With the Ambient Weather function, adesso has created a way of automatically taking local weather conditions into account in the con- figuration phase. The user can use a weather table to get an overview of the climatic condi- tions in a city.
If the heat exchanger is to be used in Las Vegas, USA, the extreme temperature ranges from -6 to 46°C must be taken into account. But Kelvion RT Select goes even further. The tool also saves a weather history that goes back up to 10 years.
