Vertiv (NYSE: VRT), a global provider of critical digital infrastructure and continuity solutions, recently introduced the new, highly efficient Vertiv™ Liebert® PDX-PAM direct expansion perimeter units with low global warming potential (GWP) and non-flammable R513A refrigerant.
According to Industry sources, the product is available now in Europe, the Middle East, And Africa (EMEA), this system is designed to operate with an eco-friendly refrigerant (as compared to legacy refrigerants) to boost increase efficiency, reliability, and maximum flexibility of installation.
Industry sources added that Liebert® PDX-PAM allows data center 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.
Karsten Winther, president for Vertiv in Europe, the Middle East, and Africa stated “In an era where efficiency and reliability are paramount, we recognize the urgent need for eco-friendly alternatives to stay ahead of regulatory requirements and provide our customers with state-of-the-art innovations. With this new solution, we’re not just addressing our customers’ current sustainability objectives; we’re actively innovating and advancing the future of cooling technology and setting new heights for efficiency and reliability.”
Lucas Beran, research director at Dell’Oro Group stated “The introduction of low GWP refrigerants for direct expansion systems marks a significant advancement in sustainable air-cooling technology. By utilizing 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 center operators aiming to achieve their sustainability goals while maintaining high operational standards.”
Industry sources added that Vertiv is leading 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 state-of-the-art electronically commutated (EC) fans, all included as standard features.
The integrated Vertiv™ Liebert® iCOM™ controller enables seamless synchronization 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.
