As artificial intelligence (AI) workloads and high-performance computing (HPC) systems continue driving unprecedented increases in data center power density, traditional air-cooling architectures are increasingly facing limitations in managing thermal loads generated by next-generation processors and accelerated computing platforms. To address these challenges, nVent has developed a portfolio of liquid cooling technologies designed to improve cooling efficiency, support higher rack densities, and enable scalable deployment of AI-ready data center infrastructure.

A key focus of nVent’s liquid cooling strategy is supporting the thermal requirements of modern AI and HPC environments. The company notes that liquid cooling provides significantly greater heat transfer capability than air, enabling more effective removal of heat generated by high-performance processors. According to nVent, liquid cooling can improve reliability, reduce energy consumption, and support the computational demands associated with AI-driven applications and high-density computing platforms.

At the core of the portfolio are Coolant Distribution Units (CDUs), which serve as the central component of liquid-cooled infrastructure by circulating coolant at controlled temperatures directly to servers and computing hardware. The company also offers its Liquid-to-Air (LTA) Sidecar Heat Rejection Unit (HRU), an integrated solution capable of supporting up to two racks of liquid-cooled IT equipment without requiring a facility water system, helping simplify deployment within existing data center environments.

nVent additionally highlights its Rear Door Heat Exchanger (RDHX) technology, including the RDHX PRO platform designed for high-density racks up to 78 kW. The system incorporates tool-less and hot-swappable components to support operational resilience while improving energy efficiency and space utilization within high-performance computing facilities. These technologies are intended to help data centers accommodate increasing rack power densities without requiring complete infrastructure redesign.

From a technical standpoint, nVent supports multiple liquid cooling architectures including indirect liquid cooling, direct liquid cooling, and hybrid cooling approaches. Direct liquid cooling transfers heat directly from components through liquid-cooled interfaces such as cold plates, while hybrid architectures combine direct liquid cooling for the highest-power components with secondary air-to-water cooling systems. This flexibility allows operators to adopt liquid cooling based on application requirements, facility constraints, and performance objectives.

With more than 15 years of liquid cooling experience, nVent positions its portfolio to support the growing adoption of AI, cloud computing, and high-performance computing infrastructure. By combining CDUs, heat-rejection technologies, rear-door heat exchangers, and scalable liquid-cooling architectures, the company’s solutions are designed to help data centres increase computing capacity while improving energy efficiency and thermal performance for next-generation digital infrastructure.
