Set up for the future: ENGIE Refrigeration impresses with customised solutions for Edge Data Centres

A lower CO₂ footprint than conventional data centres, closer proximity to end users and devices and fast provision of services with minimal latency - Edge Data Centres open up multiple added values for various sectors, from Industry 4.0 to healthcare. To ensure that Edge Data Centres run reliably and efficiently, a reliable and flexibly adaptable cooling supply is essential. With a diverse portfolio of products and solutions, ENGIE Refrigeration ensures the cooling supply of the temperature-sensitive IT infrastructure: the QUANTUM Water chiller, the most efficient water-cooled chiller series on the market, has already proven itself here. At higher waste heat temperatures above 60 degrees Celsius, the SPECTRUM water chiller guarantees a continuous cooling supply in the server rooms. If the machine room does not offer sufficient space for these cooling systems, the GENIUM supply container and the PROTECT plus housing solution create the ideal conditions for installing a cooling centre outside Edge Data Centres. Jürgen Martin, Key Account Manager Data Centres at ENGIE Refrigeration, explains: "While PROTECT plus, an extension for QUANTUM and SPECTRUM chillers with A2L refrigerants, is used in more noise-intensive applications, our fully equipped GENIUM supply container is designed for a low sound power level of around < 75 dB(A). Accordingly, we offer our customers tailor-made solutions for their individual application - even beyond the noise requirements."

Utilising waste heat profitably

With its broad product portfolio, ENGIE Refrigeration continues to enable the targeted use of waste heat in data centres. The cooling and heating experts demonstrated this in an extensive project involving ten Edge Data Centres in several German metropolitan areas. Nine QUANTUM Air chillers with integrated free-cooling and a total cooling capacity of
6.75 megawatts, seven SPECTRUM Water heat pumps in containers with a total heating capacity of 5.25 megawatts and three QUANTUM Air chillers with Green Heat Recovery (GHR) with a total cooling capacity of 2.25 megawatts not only ensure the optimum temperature here. In conjunction with the heat recovery technology, the systems also use the waste heat from cooling processes for individual local customers. Jochen Hornung, Managing Director of ENGIE Refrigeration, concludes: "This project is an example of how we at ENGIE Refrigeration are managing our cooling concepts for data centres and all other sectors towards the future - both economically and ecologically. Our efficient, sustainable and extremely flexible cooling solutions reflect our claim of 'excellence in cooling and heating' in every application and prepare operators for current and future challenges in the data centre industry."
