Data Center POST had the opportunity to connect with Paul Quigley, President of Airsys Cooling Technologies, Inc., ahead of PTC’26. With more than 36 years of experience spanning HVAC contracting, distribution, and executive leadership in manufacturing, Quigley is widely recognized for his work in large-scale, high-demand cooling environments. His career includes co-designing one of the largest VRF projects in North America and leading complex cooling initiatives across the United States. Since joining Airsys in 2021, Quigley has focused on advancing precision and liquid-assisted cooling technologies to help data center operators address power constraints driven by AI, high-density compute, and rapid digital infrastructure growth. In the Q&A below, Quigley shares his perspective on the challenges facing the global digital infrastructure industry and how Airsys is helping operators turn cooling efficiency into usable compute power.
Data Center Post (DCP) Question: What does your company do?
Paul Quigley (PQ) Answer: Airsys is an energy-focused cooling solutions company founded on a simple idea: power should serve computation, not be lost protecting it. Every system we build returns power back to the data center where it belongs. Our innovative, award-winning technologies give operators more usable power for compute, improving capacity, resilience, and overall profitability.
DCP Q: What problems does your company solve in the market?
PQ A: Airsys helps data centers recover power lost to cooling. As AI clusters push energy systems past their limits, operators are forced to choose between compute, capacity, and cost. Our cooling technologies solve that problem by returning power back to the data center, reducing stranded capacity, and giving operators more usable power for compute.
DCP Q: What are your company’s core products or services?
PQ A: We design and build the world’s most advanced cooling solutions for data centers, including:
- LiquidRack spray-cooling and liquid-assisted rack systems
- High-efficiency DX and chilled-water cooling systems
- Flooded-evaporator chillers (CritiCool-X)
- Indoor and outdoor precision cooling systems
- Edge, modular, and containerized data-center cooling
- Control systems, energy-optimization tools, and PCE/ROIP performance frameworks
DCP Q: What markets do you serve?
PQ A:
- Hyperscale and AI compute environments
- Colocation and enterprise data centers
- Modular and prefabricated data centers
- Edge and telecom infrastructure
- Education, industrial, government, and defense applications requiring mission-critical cooling
DCP Q: What challenges does the global digital infrastructure industry face today?
PQ A: The industry now operates in an environment of rapid compute expansion and structural power scarcity. Grid limitations, long construction timelines, inefficient legacy cooling, land constraints, and the explosive rise of AI workloads have created an energy bottleneck. Data centers no longer struggle with space… they struggle with power.
DCP Q: How is your company adapting to these challenges?
PQ A: Airsys has always shifted the conversation from cooling to energy stewardship. Every system we design focuses on reducing cooling overhead and returning power to computation. Our LiquidRack spray-cooling platform, low-lift CritiCool-X chillers, and high-efficiency DX systems enable operators to deploy more compute with less infrastructure. We’re also advancing new metrics – PCE and ROIP – to help operators quantify the financial value of returned power.
DCP Q: What are your company’s key differentiators?
PQ A:
- Energy-first design philosophy — our systems return power to compute
- Rapid delivery and global manufacturing — critical in today’s supply-strained market
- LiquidRack spray cooling — enabling high-density AI clusters without stranded power
- Flooded-evaporator chiller technology — high efficiency, low lift, faster deployment
- End-to-end portfolio — DX, chilled water, liquid-assisted cooling, modular systems
- Practical engineering — simple, reliable, maintainable designs
- PCE / ROIP frameworks — financial and operational tools that change how operators evaluate cooling impact
DCP Q: What can we expect to see/hear from your company in the future?
PQ A: You will see a major expansion of our LiquidRack platform, new ultra-efficient chiller technologies, deeper integration of PCE/ROIP metrics, and broader support for modular and edge deployments. We are continuing to push innovation toward one goal: giving operators more usable power for compute.
DCP Q: What upcoming industry events will you be attending?
PQ A: Events Airsys is considering for 2026:
PTC’26 Hawaii; Escape the Cold Aisle Phoenix; Advancing DC Construction West; DCD>Connect New York; Data Center World DC; World of Modular Las Vegas; NSPMA; 7×24 Exchange Spring Orlando; Data Center Nation Toronto; Datacloud USA Austin; AI Infra Summit Santa Clara; DCW Power Dallas; Yotta Las Vegas; 7×24 Exchange Fall San Antonio; PTC DC; DCD>Connect Virginia; DCAC Austin; Supercomputing; Gartner IOCS; NVIDIA GTC; OCP Global Summit.
DCP Q: Do you have any recent news you would like us to highlight?
PQ A: Yes, Airsys has expanded its high-density cooling portfolio with several major advancements:
- LiquidRack spray-cooling platform for AI clusters
- CritiCool-X flooded-evaporator chiller line
- PowerOne high-density cooling solutions supporting AI, HPC, and hyperscale growth
- New PCE and ROIP frameworks that help operators quantify power-to-compute efficiency and energy stewardship
More announcements are planned for early 2026 as Airsys continues to expand its advanced cooling portfolio for high-density compute environments
DCP Q: Is there anything else you would like our readers to know about your company and capabilities?
PQ A: Airsys is built on a simple idea: power should serve computation, not be lost protecting it. Our mission is to help operators turn cooling losses into compute gains and to make energy stewardship a competitive advantage in the AI era.
