## [Performance as Promised](https://www.dvlnet.com/blog/a-certified-promise)

 by [Jodi Holland](https://www.dvlnet.com/blog/author/jodi-holland) on 1/15/19, 7:52 AM

You probably see products with certifications everywhere. From Energy Star on your refrigerator, to a JD Power rating on your car, a UL Listing on your lamp. So, what? An organization has slapped a “we certify this product” sticker on the next new thing. What does it mean? Should you care? What clout does this sparkly label carry with it?

When an organization, such as the American Dental Association, allows Crest Toothpaste to put its recognizable “ADA Accepted” logo on their tubes and brushes, they are basically trying to assure you the following:

*"Attention consumers. We have done the testing and we have certified that this product effectively achieves what it is says it’s going to do. Don’t feel like you’re taking a huge risk. We are so confident in our rating of this product, we bet our reputation on it."*

That is why it is such a big deal that [Liebert units from Vertiv](https://www.vertivco.com/globalassets/shared/liebert-cooling-systems-ahri-certified-data-sheet.pdf) became the first U.S.-based computer room air conditioning company to have their products be certified by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI). As part of their rigorous certification program called Datacom 1360, which is for mission-critical data center and telecom cooling systems, AHRI assures customers that they’re getting the capacity and efficiency from their cooling systems.

![ahri-pic.png2](https://www.dvlnet.com/hs-fs/hubfs/ahri-pic.png2.png?width=600&name=ahri-pic.png2.png)

In addition, AHRI’s certification of certain Liebert products further validate *Vertiv’s* own ratings of their products and performance software, while ensuring product compliance with the industry’s technical standards. And, as the consumer, the certification allows for more effective comparisons between different cooling systems when you are in the decision-making phase.

We encourage you to [learn more](https://www.vertivco.com/en-us/campaigns/thermal-management-ahri/) about the Liebert products that carry the trusted AHRI Certified mark, and what it means for your data center.

## [To Replace or Not to Replace?](https://www.dvlnet.com/blog/to-replace-or-not-to-replace)

 by [Jodi Holland](https://www.dvlnet.com/blog/author/jodi-holland) on 1/7/19, 10:49 AM

Another year has come and gone. For some of you, this means your data center cooling equipment is another year older, and it may not be running as efficiently as you'd like.

So, the question becomes, to replace or not to replace? If you choose to replace the old equipment with the latest and greatest Vertiv has to offer, a whole lot of comfort and reliability will come with your purchase. If you’re on a much tighter budget, however, retrofitting your current equipment could be a viable option that will help you save energy today, while allowing it to last a few more years before you have to take the big leap to buy all new equipment. While possible equipment upgrades that can be considered include [Liebert® iCOM™](https://www.dvlnet.com/hubfs/Liebert-iCOM-System-Controls.pdf) and [Liebert® EC fans](https://www.dvlnet.com/hubfs/liebert-ec-fan-upgrades-data-sheet.pdf), one equipment replacement might be a [Liebert® DSE™](https://www.dvlnet.com/hubfs/Liebert-DSE.pdf).

 

![Retrofit-Payback-Scenario-2](https://www.dvlnet.com/hs-fs/hubfs/Retrofit-Payback-Scenario-2.png?width=800&name=Retrofit-Payback-Scenario-2.png)

Before you make up your mind though, it’s best to consider your different options and how they would effect your annual energy costs in the coming years. Would you be saving big with one option over the other? And, if so, how long will it take for these energy savings to cover the cost of the project? For a breakdown of these possible costs (and more) take a look at two options that Vertiv presents in a [retrofit payback scenario](https://www.dvlnet.com/hubfs/Retrofit%20Payback%20Scenario.pdf).

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

![liebert-dse-medium](https://www.dvlnet.com/hubfs/liebert-dse-medium.png)Columbus, 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](http://www.emersonnetworkpower.com/en-US/Products/PrecisionCooling/LargeRoomCooling/Pages/LiebertDSEPrecisionCoolingSystem-125kw.aspx) 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 advanced[Liebert iCOM™ controls](http://www.emersonnetworkpower.com/en-US/Products/PrecisionCooling/Cooling-Monitoring/Remote-Monitoring/Pages/Liebert-iCOM-S-System-Control.aspx).  

“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.

**Emerging Technologies in Controls and Automation**

Data-center cooling systems must be finely tuned for high efficiency and availability to be achieved. Most systems, however, lack the advanced controls needed to optimize thermal performance. Join us as Jason Gloeckner, Marketing Manager for Thermal Software Solutions for Emerson Network Power, explains how thermal controls are changing in response to data center trends and user preferences. Jason will discuss how new thermal-control strategies can help data center managers:
