How the ColdLogik RDHx helps HPC Applications

High-Performance Computing (HPC) is a critical tool in the world of scientific research, machine learning, and data analytics. It refers to the practice of aggregating computing power in a way that delivers much higher performance than one could get out of a typical desktop computer or workstation. HPC allows researchers and scientists to solve complex computational problems, analyze large data sets, and execute data-intensive tasks efficiently and effectively.

In the realm of scientific research, HPC applications help simulate complex phenomena such as climate change, genomic evolution, or quantum mechanics. In machine learning, HPC facilitates the training of complex models that require extensive computational resources. And in data analytics, HPC allows for the processing and analysis of vast amounts of data in a timely manner.

However, an often overlooked aspect of HPC is the need for efficient and effective cooling solutions. As these systems demand immense computational power, they also generate a significant amount of heat, which if not managed properly, can lead to system failures, decreased performance, and increased energy consumption.

This is where ColdLogik’s solutions come into play. The products offered by ColdLogik, such as their Rear Door Heat Exchanger (RDHx) Range, provide innovative and energy-efficient cooling solutions specifically designed for HPC environments.

The RDHx, for instance, operates with an Energy Efficiency Ratio (EER) of over 100 at maximum capacity, leading to substantial energy and water savings. It also helps in increasing hardware lifespan by eliminating hot spots, and operates above the dew point, eliminating the need for condensation management. This translates into reduced operational costs and a rapid return on investment.

ColdLogik’s cooling solutions not only optimize HPC operations but also contribute to environmental sustainability. Their technology isolates Global Warming Potential (GWP) gases to one centralized area and significantly reduces the volume of these gases. Moreover, their solutions save over 50,000 trees worth of carbon per 1MW ColdLogik deployment.

The impact of such innovative cooling solutions on the field of HPC cannot be overstated. By effectively managing heat generated by HPC systems, ColdLogik’s solutions enable these systems to operate at their full potential, thereby accelerating complex computations, reducing energy consumption, and ultimately advancing research and enabling groundbreaking discoveries.

In a world increasingly driven by data and computational power, solutions like those provided by ColdLogik are not just beneficial, they are essential for the continued advancement of scientific research, machine learning, and data analytics.

Challenges and Solutions


Bulk faced the following challenges:

  • How to design a solution for a colocation customer when specific IT technology, density or rack configuration is not known.
  • How to cater for the current GPU trend requiring 40-50kW+ per rack, while also considering future tech upgrades that could scale to even higher densities including Direct Liquid Cooling (DLC).
  • Find a flexible solution that allows its customer the option to select and bring in their own racks of different sizes and manufacturers.
  • Maximise operational efficiency through optimised airflow and heat rejection.
  • Reduce time for white space fit out and customer deployment by pre-installing and testing all cooling components.


The ColdLogik solution:

  • Energy Efficiency Ratio (EER) of over 100 at maximum capacity.
  • Average 15% reclaimed power for Compute by comparison to traditional cooling.
  • Potential Cooling PUE available of 1.035 with RDC.
  • Over 50,000 trees worth of carbon saved per 1MW ColdLogik deployment.
  • Adaptive Intelligence that controls the whole room temperature.
  • Higher water temperatures reduce the need for mechanical cooling, whilst maintaining ASHRAE A1 temperatures.
