DRESDEN, Germany – August 21, 2017 – Cloud&Heat Technologies, a leading infrastructure as a service (IaaS) and private cloud computing provider, today announced that it has lowered data server emissions by 180 tons of CO2 per year with direct water cooling. By combining the demand for computing power and heating energy, companies which add ten server cabinets with the Cloud&Heat Technology to its datacenters, with Power Usage Effectiveness (PUE) of 2.0, can also reduce energy costs for cooling and save heating costs. The reference data server with this technology additionally exhibits the world’s lowest PUE and thereby undercuts the PUE of flagship-data centers from Google and Facebook.

“Our numbers show an undercut of up to 4 percent for PUE and 42 percent for the Energy Reuse Effectiveness (ERE),” says Nicholas Röhrs, CEO of Cloud&Heat Technologies.  “At 4 percent, the potential savings for power costs is in two-digit-million figures for companies like Google or Facebook. The C02 emissions would also be reduced - up to multiple hundred thousand tons annually - and that is without even considering reusing the waste heat.”

The waste heat can also be used to produce cold air by using an adsorption cooling device. Buildings in major cities like New York can be provided with heat during winter and with cool air during summer time. This way, a year round usage of the waste heat can be achieved with the Cloud&Heat Technology.

How the Innovative Direct Water Cooling Concept Works

Cloud&Heat has developed an innovative direct water cooling concept which takes up the heat directly from the emitting IT components. The process follows:

Due to an optimal design of the surface coolers for each component, the heat is taken up very efficiently;

The cooling medium is transported within the server blade through copper pipes. Due to fixed pipes, possible dangers for the IT equipment such as pressure loss and leaks are reduced to a minimum;

The direction of the water flow goes from cooler components like the memory to much hotter elements such as CPU;

The whole mechanism is monitored and controlled by a redundant designed pumping unit, equipped with multiple sensors.

According to the U.S. Department of Energy, the power consumption for operating and cooling data centers reached 70 billion kWh in the USA in 2016. In 2020, the energy demand is expected to increase up to 73 billion kWh. In order to reduce high operating costs, as well as CO2 emissions, one of the greatest future challenges is the improvement of energy efficiency in data centers.

German companies are also making strides to reduce their carbon footprint.

At Eurotheum, a 100m skyscraper in the heart of Frankfurt am Main and the former home of the European Central Bank (ECB), a former TIER-3 ECB data center, is equipped with servers from Cloud&Heat Technologies. The waste heat recovery plays a major part and is taken up by the heating system of the building directly with minimal losses. The tenants of the Eurotheum from the hotel, restaurant as well as administration sector benefit from the waste heat produced by the servers due to reduced operative costs. By feeding the waste heat into the heating circuit of the skyscraper, the Eurotheum is able to save up to $47,000 Euros for heat energy, which is equivalent to the heat output of 150 low energy houses. Additionally, up to $35,000 Euros of cooling costs can be saved annually by the direct, low-loss cooling of the servers.

About Cloud&Heat Technologies

Developed in 2009 and field tested many times, the solution meets all demands for a sustainable IT-landscape. The patented technology was honored twice in a row with the German Data Center Award in 2015 and 2016. With its technology, Cloud&Heat targets companies of any size with a demand for energy efficient IT-infrastructure with the potential to drastically save on cooling as well as heating costs. Additionally, Cloud&Heat offers several years of experience in operating data centers and Cloud services based on OpenStack to its customers: from building turn-key-ready, scalable data centers, the operation and maintenance of the soft and hardware to trainings and consulting services within individual OpenStack projects.
