Data Center Cooling

​Modern Data Centers - The Role Of Water Filtration Systems

Modern data centers are complex, keeping them running safely and efficiently requires continual close monitoring and management. Many organizations consider their server room, or data center, to be 'mission critical'. Data centers are operating 24/7, making it a critical factor in the organization's success. It is to no surprise that many companies are in search of solutions that mitigate the risk of their data center failing, or experiencing any downtime at all. Among the various tasks facing data center managers, one that is reviewed and maintained on a regular basis is ensuring the temperature of the server room is just right. Should the temperature and humidity rise to excessive levels, condensation can start forming - thereby damaging the data center systems from within. Fortunately, there are various server cooling technologies that will help keep your data center temperatures at optimal levels of efficiency.

As you will learn below, water filtration systems play an important role in keeping data centers across the globe cool. Thousands of gallons of water can flow through an average data center cooling system each day. Bringing with it debris, scale, and biological activity. These unwanted particulates under 5 micron in size can build up over time, causing drastic amounts of waste (in both energy and time cleaning or repairing the system). Vortisand cross-flow microsand filtration systems are leaders in high efficiency submicron media filters, helping reduce energy, water waste, downtime and unwanted maintenance.

Power Usage Effectiveness (PUE)

The PUE metric is a popular method for calculating energy efficiency of data centers and server farms. PUE is determined by dividing the amount of power entering a data center by the power used to run the computer infrastructure within it. The PUE value is expressed as a ratio, improving your overall efficiency will help decrease your PUE value closer to 1. The use of PUE as a measurement was included in ASHRAE standard 90.1. It is important to note that these standards are continuously being revised; with the introduction of ASHRAE standard 90.4 the use of PUE as a form of measurement is no longer being required.

Cooling systems account for roughly 30 percent of consumed energy in a facility, while the data center equipment accounts for nearly 50 percent. Improving your water filtration system will help reduce wasted energy during the cooling process, along with maintenance costs due to increased fouling.

​Taking The Heat Out Of Data Centers And Server Farms

An increasing number of technology industries are turning to cooling towers to remove excess heat from buildings or processes. Server farms or server clusters are typically located between the system switches and the routers, the removal of heat from these facilities is critical to their optimal function. The advances in cluster computing, scientific simulation (such as Computational Fluid Dynamics), the rendering of detailed 3D images for health care, and the complex transactions required by web enterprises are all processed at server farms. The building's cooling capabilities play a role in limiting server performance. In many cases for every 100 watts used to power the server, 50 watts is required to cool it. The critical design parameter for these large and complex continuous systems is performance per watt. As a result, maintaining effective and continuous cooling is critical to server performance.

 Minimizing Risk - Threats To Efficiently Cooling Data Centers

The exponentially rising demand for data center services (computing, networking & storage) and IT improvements have lead to the drastic increase in water consumption by the industry. When taking into consideration the current state of water scarcity and concerns for increased droughts in certain parts of the world, there is an urgent need for data centers to consume less water, while operating more efficiently. Heat dissipation is a crucial factor to be considered for availability and reliability of IT equipment.

Having an efficiently operating and clean source of water can lead to multiple benefits. Such benefits include reduced maintenance costs, higher operating efficiencies and improved cooling capabilities of your data center. On the other hand, not having the right water treatment system can cause increased maintenance costs and inefficiencies in your effort to cooling your IT space, while putting your employees at risk to inhaling various bacteria (such as legionella bacteria).


Hard water contains dissolved compounds of calcium, magnesium and other elements. Over time these elements deposit on various surfaces and form a hardened layer referred to as scale. The layer of scale grows in thickness and reduces the effective transmittance of heat from the heat exchangers, ultimately reducing your data center cooling capabilities.


Fouling is a general term referring to the deposit and accumulation of scale, algae, suspended solids and insoluble salts on a surface (commonly found on heat exchangers and process equipment). Like scale, fouling will also cause rapid declines in heat exchanger efficiency levels, reducing your data center cooling capabilities.
