Large-scale, direct expansion thermal management unit for data centres

The Vertiv Liebert PKDX units include intelligent controls, rack sensors, and a central optimising system control to enable data centre thermal management optimisation.

Vertiv Liebert PKDX, available now throughout India is the largest single direct expansion thermal management unit designed for data centres. The units include intelligent controls, rack sensors, and central optimising system control to enable data centre thermal management optimisation.

At an average of 40 percent of a data centre’s power consumption, thermal management represents one of a data centre facility’s largest energy costs. With more capacity and higher density, there is an increased need for energy-efficient IT equipment cooling and maintaining uniform air temperature throughout the rack. In addition to availability, reliability, and energy efficiency, white space management and limiting water utilisation for cooling at the site are key features valued in selecting mission-critical infrastructure.

The Liebert PKDX is one of Vertiv’s large-scale, modular design-based, direct expansion (DX) packaged solutions, making it a flexible option for dynamic applications such as data centres, smart warehouses, battery storage systems and other large critical applications running 24×7. The standalone unit offers up to 280 kW net sensible capacity return air conditioning and can handle high air volume and external static pressure. The Liebert PKDX unit requires no white space in the data hall, is a zero water utilisation unit, and its plug-and-play design makes it very easy to install.

Ashok Yadav, director of thermal management offering/product marketing for Vertiv in India, said, “The exponential increase in the number of internet users in India, coupled with the uptick in adoption of computing-intensive workloads such as Artificial Intelligence (AI), Machine Learning, and Internet of Things (IoT), has led to the significant growth of the data centre market. Given the increased dependency on data centres, enterprises must adopt efficient and reliable IT infrastructure and cooling solutions. “Enterprises need to find ways to quickly and effectively eliminate the heat generated by their equipment. Vertiv™ Liebert® PKDX in India is to support customers’ and partners’ cooling requirements to optimise data centre sites.

With the increasing number of data centres in India and efficient thermal management systems becoming an imperative requirement, the Vertiv™Liebert®PKDX addresses variable heat load with digital and tandem arrangements. The single cabinet includes evaporating and condensing units, four sets of electronic expansion valves and an intelligent controller. Additionally, the Liebert PKDX is enabled with a proper building management system (BMS) interface and has a dual power supply with an automatic transfer switch, allowing plug-and-play configuration.

Various teamwork modes harmonise the operation of multiple Liebert PKDX units to eliminate conflicts in temperature, airflow, and humidity. The Vertiv™ Liebert® ICOM™ controller, featuring a 7-inch colour screen-based display, manages the operation of the Liebert PKDX and is integrated into the unit.
