Sustainability in focus

With indirect free cooling, a water-glycol mixture, which acts as a medium, is first cooled with outside air. Afterwards, this medium cools the data centre area via a pipe system. This differs from direct free cooling, where the outside air is used directly as a cooling source. Finally, the water-glycol mixture with the absorbed heat can be transferred to a recooler, which transmits the heat to the outside and allows the mixture to cool down again.

The PUE value, i.e. the Power Usage Effectiveness, sets the total energy consumption of the data centre in relation to the energy consumption of the IT infrastructure. Based on the firstcolo PUE value of up to 1.15, this means that only 15% of additional energy is required for services outside the IT equipment. This includes, for example, the cooling or air conditioning of the data centre space, which are required in addition to the actual operation of the hardware.

firstcolo obtains 100% of the green electricity for its data centres from the energy provider Mainova AG. This company generates the renewable energy from environmentally friendly sources such as wind power plants. The origin of the green electricity generated is clearly documented in the register of the Federal Environment Agency.

Optimal room temperature

With a room temperature between 24-25 degrees, the hardware in the firstcolo data centres on Hanauer Landstraße is sufficiently cooled, so no superfluous energy is wasted on more powerful cooling.

Security and efficiency combined

Cold aisle containment and indirect free cooling are used as cooling technologies, enabling both economical and effective cooling of the entire data centre area. Modern fan systems in combination with LED lighting and thermal cameras that detect heat spots against poorly ventilated areas or possible cable fires ensure a safe and efficient running of the fc data centres.
