Engineering Agility

CoolIT’s engineering team works closely with customers and partners to design liquid cooling technology to meet their needs. Because the pace of change and innovation for customers has accelerated, we have invested significantly in engineering, rapid prototyping and design tools.

We have expanded our capacity to design and validate liquid cooling technology at the pace AI workloads require. Our Liquid Lab Innovation Centers in Calgary and Taipei combine rapid prototyping, CFD modeling, mechanical testing, and in-house UL certification under one roof. By compressing iterations within a single controlled environment, we cut development cycles dramatically — moving from design concept to production-ready hardware in months without compromising on quality or reliability.

Every CoolIT product, from coldplate to CDU, is developed under a Design-for-X discipline, which prioritizes performance, reliability, manufacturability, and serviceability from day one.

Manufacturing Scale

CoolIT has strategically increased its global manufacturing footprint to support rapid volume ramp-up. The flagship Starfield facility in Calgary, spanning 112,000 sq. ft., anchors North American production and complements capacity in Asia. Together, these expansions have multiplied CoolIT’s total manufacturing footprint by more than 25 times compared to its original capacity — a necessary step as AI adoption accelerates.

Inside these facilities, automated assembly lines, AI-enabled optical inspections, and end-of-line functional testing maintain consistent quality at scale. This disciplined approach allows CoolIT to meet volume demands for large hyperscale and HPC deployments without sacrificing reliability.

Supply chain resilience is equally critical. CoolIT dual-sources key components and diversifies supplier geographies, ensuring production agility even in volatile global conditions.

Speed to Market and Flexibility

Innovation must match the speed of silicon design cycles. When bringing a new product to market, CoolIT works closely with customers to define performance, reliability, and production requirements.

For example, in our Liquid Lab Innovation centers, we can rapidly design, prototype, test, and validate—as well as UL certify—new products all in-house. This allows us to compress development timelines without compromising quality or reliability. Take the development of a cooling loop for a customer’s new server SKU. We can move quickly into development because we’ve already worked with silicon manufacturers to develop coldplates that are fully optimized and validated for their next-generation processors. We leverage existing components where possible to improve supplier qualification and testing cycles. Well-defined test and validation processes provide clarity and an established supplier base and high-volume manufacturing capacity mean we can scale production.

Flexibility is another necessity. Hyperscale customers rarely rely on one-size-fits-all infrastructure. Each datacenter is designed around the customer value and application to be delivered, and the infrastructure is optimized to most efficiently deliver those workloads. What this means is that we build products that use common-off-the-shelf components but are designed for the unique customer requirements. To this end, we’ve developed a portfolio of modular, interoperable components that we can use to get a product to market quickly.

The result is a practical balance: customers benefit from the performance and reliability of mature, standardized parts while still receiving a custom-engineered cooling solution tailored for their next-generation workloads.

Ready for the AI wave

Cooling will define how far AI can scale. Direct liquid cooling is not optional — it is now fundamental to sustaining performance and efficiency at densities where air cooling fails.

The post Rising to AI’s Cooling Demands: How CoolIT Delivers Speed, Scale, and Flexibility appeared first on CoolIT Systems.

This talk explores the essential role of Coolant Distribution Units (CDUs) in enabling scalable, high-density liquid cooling deployments. From managing flow rate and heat exchange capacity to ensuring temperature stability and redundancy, CDUs are foundational to the reliable operation of liquid-cooled data centers. CoolIT’s expert speakers, Kamal, Neil and Paul will share practical insights on selecting and deploying CDUs for performance, resilience, and sustainability. Watch the talk to:

• Preview emerging CDU designs built to support the demands of next-generation infrastructure
• Understand key factors that matter in CDU selection and how CDUs influence thermal efficiency and operational reliability
• Learn from real-world deployments and lessons learned

The post Cooling AI at Scale: Are CDUs the Bottleneck or the Breakthrough? appeared first on CoolIT Systems.

This study defines test parameters to assess if the 1.5 m/s velocity limit is accurate to prevent erosion-corrosion in IT cooling systems. Corrosion results from electrochemical metal degradation, while erosion is mechanical damage due to high-velocity fluid impact. Erosion-corrosion combines both, accelerating material loss. The experiment evaluates mass loss and surface roughness to determine the critical velocity at which damage rapidly increases. Copper coupons will be exposed to PG25 coolant under controlled conditions, measuring weight and surface roughness changes. Wall shear stress (WSS) is a key factor in erosion-corrosion influencing mass transfer of corrosive species. City water velocity guidelines exist but may not apply to IT cooling. This study simulates impinging jet flow to establish whether current limits are valid. Data will guide optimal velocity thresholds for liquid cooling without unnecessary restrictions, ensuring efficiency while minimizing material degradation.

“CoolIT engineered the CHx1500 to exceed AI and HPC’s most demanding cooling roadmap requirements,” said Neil Mulji, CoolIT’s VP, Product. “What we created in the CHx1500 is not only the most powerful row-based CDU unit in the market – providing the best cost per kW – but also a unit packed with all the advanced features and functionality that our OEM and hyperscale customers expect of CoolIT.”  

Leveraging 24 years of direct liquid cooling (DLC) innovation and developed in close collaboration with leading processor manufacturers and hyperscalers, the CHx1500 delivers 1500kW cooling capacity with a flow rate of up to 1.2 liters per minute per kilowatt (LPM/kW) at 5°C approach temperature difference (ATD).

CoolIT’s CHx1500 liquid-to-liquid CDU can cool 9 x NVIDIA GB200 NVL72 racks today, as well as provide ample performance for more thermally dense AI chips and servers in the future.

CoolIT’s CHx1500 CDU is not only the most compact but also the highest performer on all key metrics: cooling capacity, flow rates, pressure and density. Compared to similar units from other manufacturers, the CHx1500 provides 27% to 148% greater cooling load, 53% to 463% more cooling load density and 26% to 75% greater pumping pressure. 

The following chart shows the nominal performance of the CHx1500 and other CDUs estimated using a 4°C ATD.

Table 1: CDU Performance Comparison

Note: Estimated at 4°C ATD with PG25 Coolant using nominal performance data provided from publicly available information from each manufacturer.

For data center operators, the CHx1500 also provides superb serviceability and reliability.  The single rack-sized unit is fully front and back serviceable with hot-swappable critical components and multiple levels of redundancy.  Control of the unit is available through a 10” touchscreen or remotely through Redfish, SNMP, TCP/IP, Modbus, and several other protocols. 

Engineered to strict AI and HPC requirements, the CHx1500’s high-reliability design consists of stainless-steel piping, built-in 25-micron filters and highest-grade wetted materials, plus intelligent controls that dynamically regulate the precise temperature, flow and pressure of the coolant to the chip.

The CHx1500 is now available for worldwide orders. CoolIT offers comprehensive support and onsite services in over 75 countries, including system design, installation, CDU-to-server certification and maintenance.
