Making your infrastructure as energy-efficient as possible

To keep your carbon footprint and operating costs as low as possible, an energy-efficient cooling solution for your infrastructure is essential.

With our constant focus on efficiency, we offer solutions that incorporate all the important factors such as Free Cooling, unit design and components that keep products cost- and resource-efficient throughout their life cycle. Our team will also be happy to give you advice on how to further increase the efficiency of your individual system.

Enabling sustainable telecom infrastructure

Through constant research, development, and adaptation, we ensure that our products and systems are becoming increasingly sustainable. Our Free Cooling systems are not the only major contributor here – we are also converting our units to work with more environmentally friendly refrigerants, and with less refrigerant altogether. In this way, together with you, we can take vital steps to reduce your carbon footprint to a minimum.

Ensuring fail-safe operation

High-quality components and the solid design of our units ensure a long product life and optimum operation under all conditions. In addition, monitoring options and remote diagnosis are available to further optimize operation. These also enable rapid intervention and immediate troubleshooting in all situations to avoid possible failures. Benefit from our decades of experience and intensive research, with which we are continuously improving the operational reliability of our solutions.

Reducing maintenance time to a minimum

A long product life combined with our control concept reduces maintenance work requirements to a minimum. This significantly extends maintenance intervals and minimizes the number of on-site visits by service technicians.

A-Z Support

As your partner, we deploy our experience, expertise and technology to make sure you achieve your objectives. We are committed to accompanying you and your systems, individually and reliably – from planning to implementation right through to service, maintenance and optimization. Anytime, anywhere – we are there for you to keep your business up and running.

Our areas of application in telecom infrastructure


In telecommunications, new technologies and the resulting increase in data volumes also mean more exacting requirements and greater computing capacity for the core network. With these more exacting requirements and increasing heat loads, it is even more important to focus on energy efficiency and therefore on operating costs and the carbon footprint. STULZ solutions are the most efficient on the market thanks to our Indirect Dynamic Free Cooling developed in-house.

While the demands on the core network are increasing, it is also essential to expand the edge infrastructure, in order to meet latency and data volume requirements.

STULZ is at your side with sustainable air conditioning solutions and rapidly scalable concepts, for large and small heat loads. These enable you to achieve the greatest possible availability for your infrastructure with minimal operating costs.

It is also very important to minimize noise emissions in residential areas and near offices. STULZ offers solutions that ensure optimum operating conditions and therefore make sure all system equipment runs quietly.

The shorter range of telecommunication networks necessitates a huge increase in the number of base stations, outdoor cabinets and antennas. To ensure fail-safe operation of the decentralized nodes, reliable cooling of the various systems is essential. STULZ offers long-lasting, energy-efficient solutions with Free Cooling options. Not only does this minimize operating costs – it also helps to achieve global and regional CO2 targets.
