Vertiv Adds New Direct Expansion Cooling Unit to Enable Carbon Footprint Reduction

Published

Vertiv introduced the new, highly efficient Vertiv Liebert PDX-PAM direct expansion perimeter units with low global warming potential (GWP) and non-flammable R513A refrigerant. Available now in Europe, Middle East and Africa (EMEA), the system is designed to operate with an eco-friendly refrigerant (as compared to legacy refrigerants) to enable increased efficiency, reliability and maximum flexibility of installation.

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 recognize 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’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.”

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 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.

“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 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.”

Delinea Brings Runtime Control for AI Agents to GISEC Global 2026

Published

on

Delinea, the identity security platform that governs what humans, machines and AI agents do once they have access, today announced its participation at GISEC Global 2026. Under the theme, “From Access to Action: Governing AI at Runtime,” the company will spotlight the growing need for organisations to govern the actions autonomous AI agents take after access has been granted.

Following its release of new runtime authorisation capabilities for AI agents this summer, Delinea will use GISEC to advance the conversation around runtime authorisation, an approach designed to enforce policy on an agent’s actions within a session, at the time those actions are executed.

As AI agents take on increasingly autonomous roles across databases, cloud environments, infrastructure and business systems, the security challenge is shifting beyond authentication. While an agent may have legitimate access to a system, it can still take an action that exceeds its intended task or creates operational risk. Delinea’s runtime authorisation capabilities enable organisations to apply policy at the point of action — allowing, blocking or escalating activity before it executes.

“AI adoption is moving the identity-security conversation beyond the moment of authentication,” said Mortada Ayad, VP Sales at Delinea. “The question for organisations is no longer simply whether an AI agent can access a critical system. It is whether they can govern what that agent does once it is inside. At GISEC, we want to put that challenge, and the need for runtime control, at the centre of the regional conversation.”

Delinea has strategically adopted a channel-led presence at this year’s show, reflecting its focus on bringing these capabilities to market through the regional partners enterprises rely on to deploy, manage and operationalise complex security programmes. Through its presence at the stands of regional distributor, Shifra, and integrator partner, Defa3, the company will deepen engagement with existing partners, recruit new partners and build the specialist capabilities needed to support secure AI adoption across the region.

The approach builds on the Delinea Partner Advantage Program, launched in July 2026. The program provides partners with clearer rules of engagement, deal protection, tiered incentives and AI-driven enablement, helping them build profitable identity-security practices, while delivering stronger outcomes for customers. It is designed to support selling partners today, with expanding roles planned for managed service providers, global systems integrators, advisory partners and technology partners.

“For a capability this consequential, technology alone is not enough,” Ayad added. “Customers need partners who understand their environment, their risk and how to translate security policy into practical control. Our focus at GISEC is to equip and grow that ecosystem, so organisations can move forward with AI, knowing that authorised access does not become unchecked action.”

Delinea’s runtime authorisation for AI agents enables organisations to govern activity across the systems agents use, including databases, SSH hosts, Kubernetes clusters and cloud consoles. Through just-in-time, task-scoped access, and real-time policy enforcement, organisations can reduce reliance on standing credentials, while maintaining a defensible record of AI-driven activity.

Turnitin Expands AI Writing Detection to Support Arabic Language Submissions

Published

on


Turnitin recently announced the launch of its AI writing detection capabilities for Arabic language submissions, marking a significant step in supporting educators and students worldwide. This expansion helps equip Arabic-speaking educators with the tools necessary to safeguard academic integrity and nurture original thinking in the classroom.

As AI adoption among students becomes nearly universal, educators require solutions that promote transparency, rather than surveillance. Turnitin goes beyond simply verifying authorship, its tools support the broader learning journey, and help equip students with the critical skills demanded by today’s workforce.

“By providing Arabic-speaking educators with tools that uphold learning integrity, we ensure that they have solutions designed to support original thought and critical thinking, rather than having LLMs replace it,” said James Thorley, Vice President of APAC and EMEA at Turnitin. “While there is no substitute for knowing a student’s writing style, educational background, and institutional AI policies, this tool gives educators insights into areas where AI may have been used. Ultimately, it opens the door to meaningful, informed conversations about the responsible use of AI.”

AI writing detection for Arabic is now available through Turnitin Originality and as an add-on for iThenticate customers. Like the English, Spanish, and Japanese versions, the feature provides educators with an overall percentage of likely AI-generated content, alongside:

Detection capabilities for the leading large language models, reporting designed with educators in mind and seamless integration into existing customer workflows.
