Cooling for Every Data Center
NIMBUS Advanced Process Cooling supports every data center application, from legacy air-cooled facilities to closed-loop, liquid-cooled AI factories. Our adaptive heat rejection systems are engineered to minimize or eliminate water consumption while shifting power from cooling to your servers. Whether optimizing existing infrastructure or scaling for higher-density compute, NIMBUS ensures reliable, efficient performance under any load.
The Outdoor Heat Rejection Problem with AI Workloads
While the cooling discussion often focuses on how IT equipment is cooled inside the data center, overall cooling performance can vary significantly depending on the choice of outdoor heat rejection. Traditional heat rejection systems like cooling towers and chillers force a difficult trade-off: high water consumption versus heavy power demand.
Conventional cooling systems, such as cooling towers and chillers, introduce three major constraints that compound as AI workloads scale:
Water
High consumption increases costs and sustainability concerns
Power
Significant energy demand reduces overall system efficiency
Space
Large physical footprints limit scalability and flexibility
Left unaddressed, these constraints directly impact operational costs and time-to-revenue.
Evolving Cooling Demands Require Flexible Solutions
Cooling strategies are evolving alongside next-generation AI processors. Higher operating temperatures are making dry cooling viable in more environments, while hybrid systems remain essential for peak performance and hot climates.
Hybrid Adiabatic Cooling (VIRGA™)
- Provides additional cooling during peak heat conditions
- Reduces water usage while maintaining performance
- Critical for hot climates and legacy infrastructure
- Ensures uptime when dry cooling alone isn’t enough
Dry Cooling (Boreas)
- Ideal for higher operating temperature environments
- Eliminates water usage
- Increasingly viable with next-gen AI infrastructure
- Best suited for moderate climates and future-forward designs
Why NIMBUS for Data Centers?
Specialized Expertise
Unlike other manufacturers, NIMBUS focuses on heat rejection solutions rather than product lines. Our specialists work together with project stakeholders, bringing focused expertise to data center cooling challenges.
Made in the U.S.A.
As a pioneer in hybrid adiabatic cooling in the United States, NIMBUS offers strong domestic manufacturing and supply chain advantages that help reduce lead times and improve project reliability.
Vendor-Neutral Integration
NIMBUS solutions give you choice by offering seamless integration with any air, liquid, or hybrid cooling architecture, as well as existing BMS and SCADA platforms.
Power Savings that Drive Revenue
By optimizing cooling efficiency and lowering PUE, operators can reclaim stranded power capacity to support higher-density IT loads, directly maximizing revenue-per-rack.
Flexible Deployment
Whether breaking ground on a greenfield site or retrofitting an existing facility, NIMBUS provides the legacy-to-AI bridge necessary to meet growing power densities.
A Balanced Performance Advantage
NIMBUS helps data centers optimize across the metrics that matter most: Time-to-Revenue, WUE, PUE, OpEx, and the risks associated with traditional cooling towers.
Future-Proof Your Data Center Infrastructure
AI hardware evolves fast. Overinvesting in cooling technology that becomes obsolete before it hits its ROI break-even point is a real CapEx risk, one that NIMBUS helps you avoid. Our hybrid adiabatic approach scales alongside next-generation compute demands, allowing you to protect your cooling investment as the technology landscape shifts.
A Long-Term Partner
NIMBUS is more than a solution provider. We are your outdoor heat rejection partner for the long term, helping you adapt to evolving AI demands and future technologies.
Improve Cooling Economics
