Liebert PKDX manages variable heat loads digitally, allowing for higher return air temperatures

The Liebert PKDX tackles variable heat loads through a digital and tandem arrangement, allowing for higher return air temperatures during operation.

The massive growth in the number of users connected to the internet and the adoption of hyper-converged infrastructure and deployment of computing-intensive workloads such as Artificial Intelligence (AI), Internet of Things (IoT), and Big Data applications have contributed to the growth of global data center markets.

Unfortunately, every piece of this equipment your company possesses generates heat which can lead to problems if early measures to get rid of this heat are not taken. Cooling represents the biggest slice of the total cost in a data center. And with more capacity and higher density, there is an increased need for energy-efficient cooling of IT equipment.

Every operation of your company depends upon the instant, around-the-clock availability of computers, servers, and other electronic systems. If they aren’t working, neither is your company. Along with availability, reliability, and energy efficiency, white space management is another key in pursuing uptime in mission-critical solutions. The ability to tailor an engineered solution sets Vertiv apart from other companies.

Vertiv Liebert PKDX, the largest single DX unit configuration
It is designed for the data center with/without a raised floor and carries attributes as below.
• Modular design-based largest DX Package solution.
• A standalone unit that can offer 280 kW net sensible capacity (at 36 °C, 26% RH) return air conditioning; it can handle high air volume to 74700 CMH and high External Static Pressure (ESP) to 300 Pa.
• Liebert PKDX unit doesn’t occupy white space in the data hall and is very easy to install (plug-and-play arrangement).
• Liebert PKDX easily addresses variable heat load with digital and tandem arrangement and it operates with higher return air temperature.

Liebert® PKDX principal components:
• Fixed and Digital Scroll Compressor in tandem
• A single cabinet with evaporating and condensing unit
• Anticorrosive treated evaporator and condenser coil
• 4 sets of Electronic Expansion Valves (EEV)
• Intelligent Controller
• Dual power supply with Automatic Transfer Switch (ATS)
• Building management system (BMS) configuration enabled.

Advanced controls for efficiency, protection, and insight
Liebert PKDX Units encompass intelligent controllers, wired or wireless rack sensors, and central optimising system control to ensure that the entire data center system is optimised with the other components of the DX system. Various teamwork modes harmonise the operation of multiple PKDX units to eliminate conflicts in temperature, airflow, and humidity. The 7-inch coloured display screen-based Vertiv™ Liebert® ICOM™ 3 controller is offered in the Liebert PKDX.
