News and Case Stories

We keep you informed about the latest developments and projects.

Actively committed to climate protection

Counteracting climate change is one of, if not the, greatest challenges facing the global community today. It demands consistency of action – not just from politicians, but from business in industrialised nations as well.

We, too, are resolutely taking measures to protect the world that we want to bequeath to our children and grandchildren.

Air-based cooling systems – no CFCs and low energy consumption

Our air-based, CFC-free cooling systems are already making valuable contributions to significant energy savings and relieving the burden on the atmosphere, but deutherm is going above and beyond the call of duty.

Our air-based cooling systems enable us to help our customers reduce their reliance on fluorinated greenhouse gases such as those used in conventional air-conditioning systems. These gases are 100 to 23,000 times as harmful as CO2. In addition, the energy consumption of our cooling systems is only a fraction of that required by conventional systems.

300 climate protection certificates as compensation

We have had the greenhouse gas emissions caused by all the activities of our company recorded – including transport, assembly and sales, miles travelled, hotel accommodation, etc. The emissions balance was calculated by FOKUS ZUKUNFT using the official guidelines of the Greenhouse Gas Protocol. 300 climate protection certificates for 2022, 2023 and 2024 have now been obtained to make up for our company's CO2 output.

Climate protection in day-to-day business as well

Our day-to-day business is also oriented to climate protection – from business trips, which are taken by rail, through energy-efficient office and household technology to the paperless office, which we are striving towards.

Generation change started at Deutherm Cooling GmbH

In the past three years, Deutherm Cooling GmbH has more than doubled its sales. This very positive and continuous development caused Kuno Weiler to make a far-reaching decision for the long-term future of his company.

Michael Krämer started to work at Deutherm Cooling GmbH on November 1st. Michael Krämer will be managing partner of Deutherm Cooling GmbH from January 1st 2022, alongside Kuno Weiler. In three years, at the end of 2024, Michael Krämer will then be the sole owner of Deutherm Cooling GmbH. Kuno Weiler will then go into his well-deserved retirement to have more time for his family and hobbies.

Now that the future of Deutherm Cooling GmbH has been optimally regulated, we are again investing heavily in the company. At the beginning of December, we will move to our new office in Wehringen near Augsburg. In addition to the office, we will also have a warehouse there with storage spaces for up to 1,000 Flexiboxes and DFC-Systems, including accessories.

With these investments, we hope to be able to counteract the current cost explosion and delivery delays for almost all materials. Further positive changes are currently in planning. We will keep you informed and look forward to an ongoing good cooperation.

Protecting the climate with Boris Hermann on board

Deutherm has been supporting the Development and Climate Alliance (Allianz für Entwicklung und Klima), a German government initiative, since June 2020. On 23 November the organisation held a virtual meeting of its sponsors.

More than 200 representatives of sponsors, interested parties and cooperation partners logged on to follow livestreamed technical presentations and reflect in workshops on the latest developments and challenges.

The aim of the event was to communicate the message that the Alliance transitioned to a foundation in October 2020 and, as such, offers a reliable network – even in these uncertain times – that is developing positively. The inclusion of interested parties was also intended to attract new sponsors and enhance the recognition of the initiative. Many leading names are engaged in and for the foundation, as was evident from the event itself: The Federal Minister for Economic Cooperation and Development, Dr. Gerd Müller, spoke about the significance of development and climate protection in the Covid-19 age and the responsibility of industrialised countries to step up their efforts in climate protection. As ambassador for the Alliance, Nina Ruge spoke about the possibilities it had of being a key driver of solutions for the general challenges facing us. She reminded delegates of the need to take equal account of ecological, economic and social components in all development and climate protection measures. Even round-the-world sailor Boris Herrmann, a prominent supporter of the Alliance, logged in by video from the south Atlantic, which he is crossing alone at this very moment as a participant in the Vendee Globe race.

We would be delighted if you wanted to find out more about the Development and Climate Alliance. Do you want to become a sponsor yourself? Even better! You will certainly find some good ideas and initial information in the interview with the foundation's board members. For the Statement of Commitment, click here.

Swisscom saves twice over with deutherm cooling technology

Swiss specialist magazines Phase5 and Energeia, both published by the BFE (the Swiss Federal Office of Energy), report on high energy and cost savings that Swisscom is achieving with the aid of technical conversions in their mobile phone systems – and the clever cooling technology from deutherm is a key factor.

More than 5,000 mobile phone base stations in Switzerland ensure that mobile phone customers have comprehensive coverage. New mobile phone technology is being introduced nationwide. This conversion process also entails modernising the existing cooling technology. The old air-conditioning systems currently in place use environmentally harmful coolants, are maintenance intensive and consume far too much energy.

That was why Swisscom began to replace the existing cooling systems with modern, sustainable alternatives in 2019. The previous mix and match of many different air-conditioning systems is being swapped for five standardised devices – three based on pure free-cooling technology, like the Indoor and Outdoor Flexibox-900 and the very quiet DFC-450 system from deutherm, two with active refrigerant production. Work started on the first 1,250 sites which consume the most energy or at which the air-conditioning technology has already been in use for more than eight years.

The aim of project manager Christian Rüttimann is to convert 70% of the installations to free-cooling technology. With about one quarter of the sites having now been converted, a saving of 90% in the costs of electricity for cooling is already apparent. According to Rüttimann, the cost savings are even higher than they had originally calculated.

One of the key contributors to this improvement in efficiency is the Infrabox, a control and monitoring unit that Swisscom developed on its own initiative. The Infrabox works directly with the CC-3000 controller of the free-cooling systems (Flexibox-900 and DFC-450) from deutherm. This ensures the reliable remote monitoring of relevant operating parameters and allows them to be optimised with absolute precision. Upcoming maintenance and repair operations can be planned better and executed more cost-efficiently based on the up-to-date information about the site. It is another important contribution to the sustainability of investment in Swisscom's mobile phone network.

deutherm opens new training facilities

Our new meeting and training facilities considerably improve the conditions for professional development and seminars with customers and installation partners.

All 3 models of the Flexibox 900 (IDCA, ODCA, ODCA-DO), a DFC-450 system, a battery cooling compartment with a 450 watt 48V DC air conditioner, a split air-conditioning system and a professional 48V DC power supply as well as a mobile 7kW air conditioner can now be provided locally for trainings. The number of participants will be limited to 5 until further notice. The rooms are large enough to ensure social distancing between seminar attendees in line with hygiene regulations. One of the areas the training will focus on is the remote monitoring of the network infrastructure.

deutherm continues success story

The message in our annual report of 2019 was clear: With an increase of 50,3 % compared to 2018 in Germany and European countries our business growth was more than satisfying. And the story of success continues. In the first 6 months of 2020 we gained impressive 37,52 % compared to the first half year in 2019. An encouraging development which leads us to invest in our staff an our location in Augsburg.

deutherm supports Alliance
for Development and Climate

deutherm is taking on further responsibility for climate protection! Alongside our commitment to the Global Compact, we are now also supporting the Alliance for Development and Climate, an initiative dedicated to implementing the "Agenda 2030" of the United Nations, which aims to set the trend in climate development through the avoidance and offsetting of CO2.

Together with many partners from business, the Alliance is working to offer carbon-neutral growth opportunities in developing countries with the aim of achieving sustainable development. Renewable energy, climate-friendly agriculture and forestry and forest preservation are intended to create jobs while at the same time helping to protect the environment. deutherm is in prestigious company as a supporter.

deutherm supports Global Compact principles

The United Nations Global Compact seeks to change the world together with businesses in the areas of human rights, labour standards, environmental protection and the fight against corruption.

In a letter to UN Secretary-General Guterres, deutherm's managing director Kuno Weiler undertook to promote the underlying principles in the company's own area of influence. To quote, "We undertake to integrate the Global Compact and its principles in our business strategy, corporate culture and day-to-day business and to participate in cooperation projects which serve the general objectives of the United Nations, in particular the Sustainable Development Goals."

Sustainable economic activity is a central hub and pivot of the Global Compact and, in the opinion of the UN, of vital importance for the successful future of businesses and organisations. It begins with the value system of a business and with principles that are to apply everywhere.

The United Nations has defined ten principles for where and how businesses both take responsibility and lay the foundation for future success. In addition to the protection of human rights, they also include fundamental labour standards such as the elimination of forced and child labour and the right to collective bargaining. Other fundamental values of the Global Compact include protection of the environment, the promotion of environmentally friendly technology and the fight against corruption.

"We are not a global group," says Kuno Weiler, "but we cooperate with such companies and want to set an example together."

deutherm takes IT security seriously

1. In our own IT environment

Business espionage and IT sabotage are an increasing danger in the SME sector of the economy too. Access-proof structures are becoming ever more important for the stability and success of a company.

deutherm cooling GmbH has obtained comprehensive IT security advice from the University of Augsburg. As part of their service, the university analysed the company's in-house IT structure in conjunction with the external IT adviser and our own system administrator and confirmed the high security standard of servers and workstations. This issue will also be given high priority in follow-ups going forward.

2. In data communication from the cooling systems

The innovative and highly efficient cooling systems offered by deutherm can send and receive data for the purposes of remote maintenance. To that end, secure solutions using SNMP-V3 or on a TLS basis have been developed in cooperation with several major mobile phone operators.

Swisscom relies on deutherm technology

The Swiss telecommunications market leader Swisscom recently opted for the energy-efficient deutherm cooling solutions. The press release stated:

"Swisscom wants to increase energy efficiency by 30 per cent by the end of 2020. The "Levante" project represents another milestone for Swisscom in its bid to lower electricity consumption. Flexibox – a product made by deutherm – is the equipment chosen by Swisscom to cool its technical infrastructure in mobile base stations by using external air instead of air conditioning systems. This makes it possible to reduce the consumption of electricity for cooling by around 90 per cent. Swisscom has fitted the new system in around 20 stations so far, with another 460 set to follow. These retrofits will enable Swisscom to save approximately 3.5 GWh of electricity annually. This equates to the consumption of around 800 households. It also does away with the need for cooling agents which are harmful to the environment. The "Levante" project will not only be kind to the environment, however: as well as saving on energy costs, doing without expensive air conditioning systems will also lower maintenance costs. (...)

deutherm on course for success

Growing numbers

deutherm enjoyed a very successful first half of 2019. We recorded a 42% jump in sales compared with the same period last year, with incoming orders growing by 45%. Demand for the latest generation of mobile cooling systems was particularly high.
