Designed to save millions of gallons of water and increase energy efficiency by up to 50 percent

liebert-dse-mediumColumbus, Ohio [September 16, 2015] – Emerson Network Power, a business of Emerson, (NYSE: EMR) and the world’s leading provider of critical infrastructure for information and communications technology systems, today announced that the California Energy Commission (CEC) has approved the use in California data centers of the Liebert® DSE thermal management system with the Liebert EconoPhase Pumped Refrigerant Economizer. The Liebert DSE system represents a break-through technology that uses no water and saves up to 50 percent of thermal energy, through its patented design and advancedLiebert iCOM™ controls.  

“The Liebert DSE system is a great environmental steward. When used in a typical mid-sized data center of one megawatt load, the Liebert DSE is significantly more efficient than current cooling systems, and eliminate the use of around four million gallons of water each year. If deployed broadly in California data centers, the Liebert DSE with EconoPhase could save hundreds of million gallons of water every year,” said John Peter Valiulis, vice president North America marketing, thermal management, Emerson Network Power.
The CEC has approved the Liebert DSE system with Liebert EconoPhase as a prescriptive economization option, as part of Title 24 of the the CEC’s 2103 Building Energy Efficiency Standards For Residential and Non Residential Buildings, meeting the code’s requirements for energy efficiency and its prescriptive requirements for economizers.
The Liebert DSE system eliminates the need for any water in the heat rejection process and associated chemical water treatment, and it eliminates the risk of exposure to harmful waterbound bacteria. In addition, the Emerson modeling for the CEC compliance program demonstrated an 8 to 10 percent reduction in the data center Time Dependent Valuation measure, compared to the water economizer prescriptive option. The Liebert DSE system design also reduces or eliminates several of the power components associated with water economizers. In actual usage, the entire Liebert DSE system has demonstrated thermal system energy savings of up to 50 percent over older legacy systems.

When Should You Consider Building a New Data Center? Case Study: Paragon Internet Group

by Emerson Network Power on 11/19/14 9:25 AM


IT departments today are all about speed – adding more applications faster to satisfy voracious global appetites for mobile, social media, streaming video and other resource-intensive applications. These applications must be available, regardless of their impact on critical infrastructure performance. If growth is stretching your resources too thin, you must take action to ensure availability. But because IT organizations are pressured to lower costs, you have to build an unassailable business case when deciding how to expand.

A variety of solutions are available for upgrading and expanding your critical infrastructure, including building a new data center, but how do you know which option is best?

Because you can take many actions short of building a new data center to improve your critical infrastructure, you may want to consider building new only as a last resort.
Building new is expensive and difficult. Factors such as getting a loan, finding a location and determining if you can get fiber optic cable all come into play. It can take three years before the new space is operational, and managing logistics for a move is challenging.

Still, there are times when building new is a good choice:

  • Your business growth is through acquisition, and you need to consolidate a number of acquired data center You may have to build new to accommodate them.
  • You don’t have a disaster recovery site. You can build new and use the old facility for this purpose.
  • Your equipment is so old and poorly maintained that it’s not worth it to upgrade. Building new is an opportunity to take advantage of new, more efficient technologies.


Here is an interesting case study about Paragon Internet Group in the UK.

What about you? Have you assessed and optimized your existing critical infrastructure or have you preferred to invest in a new data center project?
