INTELLIGENT BRANDS // Data Centres

Liebert PDX-PAM allows data centre owners to comply with the EU F-Gas Regulation 2024 , 573 and enables their pressing sustainability goals . The non-flammable R513A refrigerant provides up to a 70 % GWP reduction when compared to the traditional R410A , without compromising safety or reliability . No additional safety devices are required , as is the case for units using flammable refrigerants , enabling reduced installation costs and CAPEX .

“ In an era where efficiency and reliability are paramount , we recognise the urgent need for eco-friendly alternatives to stay ahead of regulatory requirements and provide our customers with state-of-the-art innovations ,” stated Karsten Winther , President for Vertiv in Europe , Middle East and Africa .

“ With this new solution , we are not just addressing our customers ’ current sustainability objectives ; we are actively innovating and advancing the future of cooling technology and setting new heights for efficiency and reliability .”

Liebert PDX-PAM is available from 10 kW to 80 kW with a wide range of airflow configurations , options and accessories , making the unit easily adaptable to various installation needs , from small to medium data centres including edge computing applications , UPS and battery rooms . In conjunction with the Liebert PDX-PAM units , a wide choice of cooling solutions is available for managing heat rejection externally , depending on the specific system configuration .

Vertiv is in innovation and raising the technology threshold with Liebert PDX- PAM , a low-GWP , non-flammable R513A refrigerant solution with inverter-driven brushless motor compressors , staged coil design with an innovative patent-pending filter , electronic expansion valves and stateof-the-art electronically commutated , EC fans , all included as standard features . The integrated Vertiv Liebert iCOM controller enables seamless synchronisation of these components , allowing complete modulation of performance .

This way , the Liebert PDX-PAM unit can adapt to changing operating conditions and heat load efficiently and reliably . The full continuous modulation capability significantly reduces the annual power consumption , resulting in a more cost-effective solution , thanks to the enhanced part load efficiency and precise monitoring of the machine ’ s operation , facilitating performance tracking and more timely and effective maintenance , thereby creating opportunities for predictive maintenance actions .

“ The introduction of low GWP refrigerants for direct expansion systems marks a significant advancement in sustainable air-cooling technology ,” said Lucas Beran , Research Director at Dell ’ Oro Group . By utilising low-GWP and non-flammable refrigerants , Vertiv complies with EU F-Gas Regulation requirements and aims to reduce carbon footprints without compromising on safety or efficiency .

This innovation is significant for data centre operators aiming to achieve their sustainability goals while maintaining high operational standards . p
