Latest news about COOLtec
We would like to invite you to our booth at DATA CENTRE WORLD in Frankfurt. 250+ exhibitors, 250+ speakers and exactly 324 conference sessions are waiting for you for the comeback of the year! Take the opportunity and experience innovative data centre air conditioning solutions from our partner HiRef in conversation with our experts.
Germany is constantly changing. More and more companies, public facilities, medium-sized firms, data centre operators and IT infrastructures are taking matters into their own hands in a number of ways. They establish powerful data centres in their area, renew and extend existing data centres or use the technological innovations from service providers.
It does not matter on what level your data centre currently is. There’s only one way to optimise it: visit Data Centre World 2020, completely free of charge!

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.
Luca Riesener is the new Regional Manager North-West with the catchment areas NRW and Niedersachsen with effect from 01 October 2021. The qualified Industriekaufmann and Bachelor of Arts Business Administration was most recently a project manager for special projects in the field of data centre air conditioning and therefore has extensive knowledge of the refrigeration and air conditioning industry.

We look forward to working with Mr Riesener and wish him every success at COOLtec.
COOLtec Systems - Your Partner for IT Cooling
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.
In order to create a stronger customer focus in the Berlin area and the neighboring states, we have decided for the new office with modern business and conference rooms.
Groß‐Berliner Damm 120a
We would also welcome our new colleague Tobias Wittzorreck. He will be responsible as project manager and technical sales in the East region.
We wish our Berlin team all the best and lots of success in the new office.
COOLtec Systems delivered the first two HiRef CO2 chiller of the CDA series in Germany. The refrigerant R744 is environmentally friendly, because it has a GWP value equal to 1.
It has all the characteristics to become the refrigerant of the future, as it is not bound by the new regulations that aim to limit greenhouse gas emissions. In addition to free cooling, the unit are also equipped with an adiabatic humidification system (humidification mats), which increases thermodynamic efficiency.
Everyone is talking about sustainable cooling solutions - we are already implementing it at the customer's level!
Mr. Hülskamp is now available to our customers for quotation preparation and technical advice under the following contact details:

We wish Mr. Hülskamp a great and successful start at COOLtec Systems.

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.
- High refrigeration capacity.
- CO2 is an environmentally friendly natural refrigerant. It has no negative impact on the ozone layer.
- Extracted from the air we breathe and therefore naturally occurring.
- Only the "excess production" of bound CO2 is harmful to the environment.
- Low refrigerant prices, high and long-term availability.
- No disposal and recovery costs.
- Safety: CO2 does not burn and is non-toxic -> classification A1.
