07-2022: New Magenta data centre opened in Graz

Ceremonial opening for official start-up

The groundbreaking ceremony for the data centre at the Graz location took place in spring 2021. The specialist COOLtec Systems was responsible for the planning and realisation of the data centre. Completion is now on schedule one and a half years later: the official start of commissioning took place with an opening ceremony on 23 May. Invited guests were able to take a first look at the new data centre. Among them were Provincial Governor Hermann Schützenhöfer, Provincial Economic Minister Barbara Eibinger-Miedl and City Economic and Cultural Councillor Günter Riegler.

A total of 380 server cabinets with an output of up to 3.6 megawatts are operated on an area of 1,120 m2. The high-performance digital infrastructure opens up new possibilities such as additional capacity for gigabit internet, 5G mobile communications and HD television, from which Magenta customers in Styria and the southern regions of Austria can benefit immediately. For business customers, new innovative products are emerging such as the provision of data centre space.

As a data centre operator, COOLtec Systems therefore focuses on energy efficiency and sustainability. Water-cooled systems and air-conditioning cabinets with indirect free cooling are used for cooling. This ensures the highest possible system efficiency and operational reliability.

10-2021: Chiller with natural refrigerant R744 (CO₂)

Air- and water-cooled with modulating compressors

The new CO₂ chillers from our partner HiRef have been developed for applications where high performance and environmental compatibility are paramount. The air- and water-cooled chillers are operated with CO₂ as refrigerant (R744), which is environmentally friendly and also has a GWP of 1.

The natural refrigerant R744 has all the properties to become the refrigerant of the future, because it is not bound by the new regulations (F-Gases Regulation), which aim to limit greenhouse gas emissions. Unlike conventional HFCs, no direct oxygen deficiency occurs in the event of a CO₂ leak, as CO₂ is not toxic in low concentrations. R744 is extracted from the air!

Funding and certification
With a GWP value below 750, there is the possibility of a refrigeration subsidy, for example from BAFA, BMU or EEW. Subsidies can amount to a maximum of 40%. Each subsidy application is subject to a case-by-case review.

We will be happy to advise you on CO2 as refrigerant and on our chiller.

08-2021: Topping-out ceremony and construction progress Data Center GRAZ

In January 2021, the first earthworks for the new COOLtec data center in Graz began, followed by the shell construction and work in the outdoor area, which is necessary for a safe operation of the data center. On July 13, 2021, the topping-out ceremony finally took place on site at a sunny 30 °C with many companies and employees involved in the project. Due to the current situation, the celebration was smaller than originally planned. Nevertheless, Managing Director Harald Köfler was able to thank the representatives of Magenta (T-Mobile Austria GmbH), planners, surveyors, building construction and building services contractors, as well as all other supporting persons. 

In the last 4 weeks, the interior construction with TGA as well as the first preparations of the server rooms have progressed. In the meantime, all redundant water-cooled chillers, 14 dry cooler and a lot of high-efficiency close control units and rack coolers (HRCC) required for the 1st data center part have already been delivered and partly installed. This will ensure constant temperatures and humidity levels, continuous air exchange and high operational reliability. Finally, a total number of 380 server racks with an output of up to 3.60 MW are to be operated and cooled in a fail-safe manner.

The data center is now scheduled for completion at the end of the year and will then enter a 3-month test operation.

As data center operator, COOLtec is responsible for the entire project management, planning, construction and operation of the 3.60 MW data center. The main focus of one of the most modern data centers in Europe is energy efficiency and sustainability. Furthermore, the data center will be built and certified according to EN 50600, the latest European standard for data centers.

03-2021: Air/air system with adiabatic system with refrigerant R744 (CO₂)

Once again, COOLtec distinguished itself as an expert in the air conditioning of data centers. At the end of 2020, an existing refrigeration system in an Innsbruck data center was replaced by a HiRef air/air chiller HDB 0060 with refrigerant R744 (CO₂). The entire project control, dismantling of the old system, delivery and installation of the new system was taken over by COOLtec Austria. The special feature of the R744 system with a GWP=1 is that 3 complex operating modes (indirect free cooling / indirect free cooling with adiabatic spraying / mechanical cooling by means of CO₂ screw compressors) were combined in an HDB 0060 with a cooling capacity of 55 kW.

• New refrigeration plant for a data center at the Innsbruck site.
• Ensuring 100% security of supply combined with state-of-the-art technology.
• COOLtec carried out a site analysis over several months to determine the actual requirements on site.
• Use of the natural refrigerant R744 (CO₂).
• Dismantling of the old plant, delivery and installation of the new units as well as complete project management by COOLtec Austria.

• Energy efficiency
• Future technology
• Reliability 
• Operation/Service.

• The indoor air of the data center and the outdoor air do not mix.
• Dust and pollutants do not enter the rooms, no further filter is necessary.
• Compact design (monoblock).
• Low PUE and WUE values.
• Water saving function and legionella-free system.

02-2021: New COOLtec data center in Graz

In Graz, one of the most modern data centers in Europe is being built on behalf of the telecommunications provider Magenta Telekom. From 2022, this will provide additional capacity for gigabit Internet, 5G mobile communications and HD television for Magenta customers in Styria and southern Austrian federal territories. New innovative products such as the provision of data center space are emerging for business customers. The new COOLtec Systems data center, which plans and manages the entire project, is being built and operated. With this project, Magenta is investing a double-digit million amount in the digital future of its styrian customers and in a highly efficient digital infrastructure for the styrian eonomic location.

Cooling and supply energy are two major challenges. As a data center operator, COOLtec Systems focuses on energy efficiency and sustainability. For cooling, water-cooled systems, as well as climate cabinets with indirect free / open cooling are used. In this way, the highest possible plant efficiency and operational reliability are achieved. Energy efficiency, and thus one of the most important criteria of a data center, is measured worldwide using Power Usage Effectiveness (PUE), a value that puts the energy consumed in relation to the energy input. While a European data center averages 1.30 PUE, the data center in Graz operated by COOLtec Systems achieves a significantly more efficient and sustainable result of 1.15 PUE. It is planned to have the data center certified according to the latest European standard for data centers (EN 50600).

"It is important to us at the same time a grate challenge to build and ultimately operate one of the most modern and energy efficient data centers of Europe for our future tenant Magenta Telekom. Our companies have a long-standing partnership and many successfully implemented projects," said Harald Köfler, Managing Director of COOLtec Systems Austria.
