Ready for What’s Next.


Aligned’s ExpandOnDemand™ designs offer customers the flexibility to seamlessly pivot and scale to support shifting computing environments – no matter the application, density requirement, or cooling solution. With Aligned’s DeltaFlow~™ and Delta3™ cooling technologies, we’ve made it easier than ever for customers to make the move from air-cooled to liquid-cooled systems, or to deploy hybrid cooling systems – combining both air and liquid – in the same data hall.


Decade of Cooling Innovation & Expertise

We’ve been innovating cooling technologies for more than a decade to help transition customers from air to liquid cooling or hybrid cooling environments with proven, turnkey cooling solutions. We also work closely with customers, leading server and chip manufacturers, and leaders in the AI space to ensure we’re ahead of the curve and help customers be ready for what’s now, and what’s next.

Find Your Flow: Air, Liquid, or Hybrid?

The Future of AI Infrastructure Cooling is Here.

The GPU and TPU clusters essential to running artificial intelligence, high-performance computing, and machine learning applications require massive processing power, pushing densities far beyond the average kW per rack. Our scalable infrastructure and flexible cooling technologies are designed to meet the increased density requirements and rising temperatures of these next-generation technologies. That’s where DeltaFlow™~ liquid cooling comes in.

Why DeltaFlow~?

Liquid to the X

Our scalable & universal architecture supports all of today (and tomorrow’s) cooling requirements: Liquid to the chip, Liquid to the rack, Liquid to the tank, Liquid to the max.

Water, Your Way

The right balance of turnkey solutions and customization to provide customers with flexible designs within a standardized delivery process to streamline the deployment and reduce cost impacts, time delays and risk.

Sustainable & Efficient

Designed with efficiency in mind, DeltaFlow~ leverages Aligned’s standard closed loop system, using no outside air or water.

Liquid… Without the Lift

Seamlessly shift to liquid cooling or integrate liquid-cooled systems in the same data hall as your air-cooled infrastructure – all in a live environment. No complete retrofit or separate build-to-suit necessary. BYO CDU/HDX – or just leave it to us…

Grow with the Flow

Modular approach to liquid cooling – support density increases vertically within the rack or horizontally with additional rack positions. Seamless integration with Delta3, unchanged power requirements, compatible at existing facility water temperatures.

[Exponentially] Grow Your Cooling Capacity

Supports the hardware and processing requirements of the AI and HPC lifecycle, from training to real-time inference. Designed to handle the heat, DeltaFlow~ cools densities of 3-300 kW per rack, and beyond.

Case Study: Cooling the Supercomputers of Our Environmental Stewards

A government agency with thousands of engineers and scientists who use high-density supercomputing to predict and respond to climate change and other environmental challenges selected Aligned as its data center provider. 

Challenge: The customer was looking for a provider with an ability to understand their needs and work with different technology partners to provide an optimal solution that addressed its cooling and scalability challenges. The agency previously used rear-door heat exchangers to cool their environment. 

Solution: Aligned integrated our patented and award-winning Delta³ cooling technology with the agency’s water-cooled infrastructure to accommodate the high temperatures associated with supercomputing. Aligned’s cooling systems are designed to be easily, efficiently and cost-effectively configured for supercomputing.

Results: Aligned ultimately saved the government agency millions of dollars in upfront capital expenditures and provided it with the ability to scale their solution quickly, seamlessly and cost-effectively, as needed. In fact, Aligned gave the agency the scalability and flexibility to double their operations in the same space, along with the ability to grow into the solution over time, which will provide additional significant savings.


Delta Cube (Delta3) is an air-cooled system that supports power densities upwards of 50 kW per rack. Delta3 enables your data center to use less space, power, and zero outside air and water (thanks to Aligned’s closed loop design). It can easily integrate with Aligned’s DeltaFlow~ solution to accommodate AI /ML and HPC deployments.

Rather than pushing cold air into the data hall, Delta3 cooling technology captures and removes heat at its source, resulting in a hyper-scalable and ultra-efficient environment that dynamically adapts to customers’ IT loads.

How It Works

Heat Absorption

Utilizing the buoyance of hot air and efficient coil technology, heat gets absorbed. The result is that fan power is reduced to 1% of IT load versus 10% for a typical CRAH unit. This provides great benefit to both the transporting and rejection of heat. The Delta³ removes heat at the source, drawing hot air from the rack and channeling it through coils.

Heat Rejection

Heat is absorbed and transported by the Delta³, but it is the chiller that rejects the heat into the atmosphere. Even on the hottest day of the year, Aligned’s cooling systems offer industry-leading PUE.

Waterless Design

Delta³ is combined with a state-of-the-art waterless heat rejection system to create a sustainable, waterless solution. This technology delivers meaningful efficiency enhancements across rising rack densities and next-generation workloads for maximum flexibility and adaptability, regardless of altitude or geographical climate zone.

Why Delta³?

Unparalleled Air-Cooling Capability

Delta Cube (Delta³) is the industry’s only air-cooled system capable of supporting high, mixed, and variable power densities exceeding 50 kW per rack in same row, without stranding capacity.


Our modular design allows customers to deploy what they need, where, and when they need it, and reconfigure as their needs change. Aligned pre-fabricates components for easy, fast, and efficient deployment so you can scale vertically or horizontally.


IT loads can vary. Delta³ responds quickly and easily, optimizing in real-time. Our Delta³ arrays are close coupled with the racks, enabling the heat removal system to instantly ramp up or down based on server demand. Our variable fan speeds and pumps respond in real-time to changing loads, dynamically addressing your needs today – and tomorrow.

Waterless & Highly Efficient

Delta³ delivers industry leading PUEs to support your sustainability goals. The technology utilizes less energy and a closed loop system to eliminate water usage and enhance efficiency, reducing environmental impact and lowering your TCO.


As a testament to Aligned’s focus on innovation, energy efficiency and sustainability, our Delta³ cooling technology has received a number of awards. These recognitions include the Edison Award, which puts us in the ranks of game-changing companies like 3M, Caterpillar, and Tesla.
