•Cooling for Data center in a digitalized word

World is increasingly digitalised and Data Centres accounting for about 3% of global electricity demand.

• +40% of Data center Energy is related to cooling System

• Increasing Data Center temperature is a viable way to improve efficiency and reduce Energy consumption

• ASHRAE, in its guidance on Data Center temperatures, has increased its “recommended” and “allowable” temperatures.

Indirect Air Expansion Economizer – OPEX reduction

• Indirect air Economizer Ecoflair takes power that would be used for cooling and makes it available for Data Centeroperations.

• Evaporative cooling only even with hot air and low relative humidity

• Trim cooling to supplement the free cooling only at very high temperature and high relative humidity

• Designed to scale with the growing demands of today’s Data Centers and to save valuable white space


Traditional temperatures do not optimize summer and economization mode

It is advantageous to move from traditional 7°C or 10°C operation to higher values, up to 20°C

Specialized chiller and CRAH designed for high water temperatures for a Data Center gives benefits as follows:

To improve OPEX by increasing EER and/or extending the free-cooling operation and bordering the main ref. components life-cycle

To allow CAPEX reduction since the chillers can be downsized
