At first glance, a motion and control company on the ISC show floor might seem peripheral to a conference focused on supercomputing. However, Parker Hannifin is at the heart of one of the most critical challenges in HPC today: managing heat and energy at scale.
We spend a lot of time discussing faster chips, bigger systems, and ambitious AI workloads. But if we look closely at where the real bottlenecks are emerging, the conversation is shifting – it’s no longer about compute, it’s about what it takes to run that compute.
The reality of today’s HPC environments is that GPU clusters are pulling an astounding 80 to 120 kW per rack, AI training tasks are running continuously at peak load and power, and facilities are hitting power and thermal ceilings long before their compute ceilings. In this context, cooling is no longer a facilities topic – it’s a system design constraint.
Many in the industry recognize that the shift to liquid cooling is not a speculative future topic, but rather an active development. The data is clear. Power densities are rising at an unexpected rate, AI workloads generate more heat and require continuous operation, and facilities are hitting their operational limits well before reaching their computing capacity.
The pivotal question now is how to implement liquid cooling effectively, and this is where Parker Hannifin plays an essential role. How do you connect and disconnect systems safely? How do you maintain them without downtime? How do you scale from a handful of racks to an entire facility?
These are operational questions and they translate into very concrete needs, such as leak-free connectors, quick disconnect couplings, fluid control systems, filtration, and precision-engineered components that keep liquid cooling infrastructure stable at scale.
Parker Hannifin supports modern HPC and AI platforms with direct liquid-cooling technologies, enabling efficient server-level and rack-level cooling and robust cooling circuits for high-density data centers. As a member of the Open Compute Project, they also align their solutions with emerging OCP designs and provide reliable global supply to customers.
Not every ISC attendee will need to engage with Parker Hannifin directly, but for some, this is highly relevant and likely urgent. If you’re planning or scaling AI infrastructure, you’re probably facing thermal limits. The question is how to move forward without constant redesign. If you’re responsible for facilities or expansion, the decisions you make now will have long-term implications, and getting cooling right is no longer optional if you’re integrating or delivering systems; reliability matters. Often, the weakest point is not the compute itself but the systems surrounding it. If you’re working in thermal or mechanical design, you already understand where the real risks lie.
What’s interesting is not just that Parker Hannifin is exhibiting, but why companies like this are becoming more visible at ISC. It reflects a broader shift in the conversation – from peak performance to sustained performance, from system specs to system operability, from innovation to implementation at scale.
We’re reaching a point where the limiting factor is no longer how powerful systems can be, but how efficiently and reliably we can run them. Parker Hannifin may not be a part of the HPCstory in the traditional sense, but they play a crucial role in making that story work in the real world. Because at the end of the day, if you can’t cool it, you can’t run it. And that’s the conversation worth having.
You can speak to Parker Hannifin in Hall H, booth F50, from Tuesday, June 23, to Thursday, June 25.
