Reliable and energy-efficient data centre cooling

PCM solutions for data centres

Operational reliability and energy efficiency are key considerations in the design and management of modern data centres. Not only from a sustainability and corporate social responsibility perspective, but also from an economic point of view. As ICT services continue to grow, the power density of IT equipment increases. Existing data centres are becoming more densely occupied and place increasingly higher demands on cooling systems. A stable, reliable and energy-efficient cooling solution is therefore essential.

The power of PCM

With the PCM Data Centre Cooler, Autarkis offers an innovative solution that stores thermal energy in Phase Change Materials (PCM), integrated into a Close Control unit. The system uses well-filtered outdoor air for free cooling and provides a reliable, energy-efficient and low-maintenance cooling solution. The PCM absorbs heat when the heat load in the server room increases and releases the stored energy again when outdoor conditions allow. This helps to stabilise both the temperature and relative humidity within the data centre. Thanks to this thermal energy storage, a stable climate can be maintained with very low energy consumption. Air movement is provided by energy-efficient EC fans, enabling exceptionally high energy efficiency.

Cooling modern data centres

Modern server equipment can operate reliably at higher supply air temperatures of approximately 23 to 27°C. This allows free cooling to be used during a large part of the year. PCM acts as a thermal buffer that absorbs temperature fluctuations and reduces the load on the cooling system. The result is a more stable temperature, reduced use of mechanical cooling and lower energy consumption.

Autarkis provides PCM solutions for various types of server rooms and data centres:

  • Small server rooms – approximately 5 m² floor area and 5 to 12 kW installed IT capacity.
  • Medium-sized data centres – 10 to 100 m² floor area and 12 to 100 kW installed IT capacity.
  • Large data centres – from 100 m² floor area and more than 100 kW installed IT capacity.

For larger data centres, we develop customised solutions together with specialised partners, integrating PCM into a future-proof cooling concept.

The benefits of PCM for data centres
