Hamburg, May 30, 2016 – Leading global mission critical cooling solutions provider STULZ announced a strategic investment and commercial partnership with CoolIT Systems, Inc. (CoolIT), a global manufacturer of energy efficient Direct Contact Liquid Cooling (DCLC™) technologies for High Performance Computing, Cloud and Enterprise markets.

The commercial partnership will enable the two companies to cooperate closely in delivering unique Chip-to-Atmosphere solutions across the globe. Both parties remain independently owned and operated.

"STULZ has identified Chip-to-Atmosphere cooling solutions as a growing market segment for data center environments," said Joerg Desler, President of STULZ USA. "This alliance with CoolIT allows us to offer customers more complete solutions that involve capturing the heat at source inside the servers and moving it out to the atmosphere with STULZ technology."

CoolIT's DCLC technology uses the exceptional thermal conductivity of liquid to provide concentrated cooling to the hottest components inside a server, enabling very high density configurations. CoolIT's centralized pumping liquid cooling solutions can be tailored to any server layout and have already been adopted by many server manufacturers as a reliable technology that is covered under standard warranties.

"Partnering with such an influential solution provider as STULZ provides a tremendous worldwide capacity to our company," said Geoff Lyon, CEO & CTO at CoolIT Systems. "This strategic relationship increases our ability to better serve the data center industry with forward thinking designs, solutions and services."

"CoolIT Systems is attractive to the global STULZ Group because they align well with STULZ' history of bringing innovation and highly efficient technology to the data center market," said STULZ USA Vice President Brian Hatmaker. "We see a growing need in the market for more flexible solutions to support high performance and high density compute applications. Chip-to-Atmosphere solutions will generate immediate CAPEX and OPEX savings with minimal footprint requirements."

The Chip-to-Atmosphere concept will be discussed in detail at ISC High Performance 2016 in Frankfurt during CoolIT Systems Exhibitor Forum Presentation: 4.40pm on Tuesday 21 June at Booth 500, Hall 3, Messe Frankfurt. Technical experts will also be available during ISC16 to answer any questions at CoolIT Systems booth, #1210.

As long as data centers are predominantly located on so-called greenfield sites outside of urban centers, noise emissions are not a major issue. However, these days even large data centers are being built ever closer to populated districts, so that data center operators can no longer avoid tackling the subject of noise optimization. This is especially the case in Germany, where strict noise regulations must be met, particularly in the hours of evening and night. Industrial and service companies – not to mention operators of concert halls and sports facilities – could tell us a thing or two about conflicts with local residents who say they are disturbed by noise. For a data center running in continuous operation 24/7 all year round, there is genuine cause for concern.

Avoiding critical thresholds from the start

To prevent potential conflict long before it rears its ugly head, data center operators must consistently use solutions with noise emissions that do not come anywhere near critical thresholds. Of course, this also applies to cooling systems with compressors, pumps and fans that can produce not inconsiderable noise. Here, we recommend only installing systems and components that are so quiet that their operation is unproblematic, even at night time. However, what sounds good in theory is not always simple to achieve in practice. A classic dilemma is posed by chillers, which exceed approx. 500 kW of cooling capacity and are situated on or next to a data center. The lowest noise emissions would be achieved using soundproof encapsulated compressors and maximum size fans, which produce the necessary airflow with comparatively low speeds and can also keep noise to a minimum – as a system. However, it is evidently not easy to reconcile soundproof encapsulated compressors and large fans with the standardized sizes of chillers. Hence the restrictions on length and width imposed by chillers mean that smaller fans are generally installed. These deliver the necessary capacity, but only at the price of higher speeds, which increases both noise emissions and energy costs.

The rise in heat loads that goes hand in hand with the increased heat density in today's data centers has made the problem even worse: in order to overcome the resulting amounts of heat quietly and efficiently, even more chillers would in fact need to be installed on numerous data center sites. Sometimes, however, there is insufficient space for this, so that the existing CW systems are under even more load than they were already. The result is higher electricity costs and high noise emission.

To provide data center operators with a way out of this dilemma and enable chillers to be used in residential areas, too, quite a number of manufacturers are equipping their fans with noise-reducing diffusors. Hamburg-based precision air conditioning specialist STULZ, on the other hand, is taking an alternative route, and manufactures its Cyber Cool 2 chillers with a view to reduced noise levels right from the start. Even during the development phase, thorough research has gone into compressors, fans and pumps, to examine their noise emissions during operation. Based on the results of these tests, systematic measures have been taken to minimize the amount of noise generated.

Soundproof encapsulated compressors, maximum size fans

The first approach to tackle noise reduction involved the compressors. In some chillers, they are so exposed that their operating noise is diffused into the environment largely unfiltered. Compressor housings, too, are frequently not noise optimized and, depending on their design, can even increase the noise level. At STULZ, on the other hand, the compressors are housed in a special, soundproof encapsulated chamber. Like the walls of a recording studio, their interior walls are completely lined with sound-insulating material, so that as little noise as possible reaches the outside. This first step in itself has greatly reduced noise emissions.

While the development of a soundproof encapsulated compressor chamber was a solution that enjoyed the benefit of experience from other industries, the question of optimizing fan noise levels was considerably more complex. Here, we needed to design a compact construction that enabled noise and efficiency values to be optimized while adhering to the chillers' standard surface dimensions. STULZ solved this difficult task by installing maximum size fans. These make the best possible use of the available space, and are lined up next to one another so closely that you can barely slip a proverbial sheet of paper between them. And finally, with diameters of 910 millimeters, they are so large that they can move the necessary volumes of air removed at moderate speeds, thereby working quietly and energy efficiently. In order for the strengths of this new fan system to be exploited to the full, the entire air conduction system, from the intake through the heat exchangers to the fans, had to be redesigned.
