Data centers sit at the center of today's AI adoption. These facilities store and serve the data that AI systems train on and recall, and the denser hardware behind those workloads produces more heat than ever. That makes cooling one of the most important decisions in any build. [Data center cooling systems](https://opendock.com/en/industries/data-center/) use air-based or liquid-based methods to keep servers running 24/7 without overheating. Without proper measures in place, data centers risk system failure and data loss. In Uptime Institute's annual outage analysis, 13% of organizations said [cooling was the primary cause of their most impactful outage in 2022](https://datacenter.uptimeinstitute.com/rs/711-RIA-145/images/AnnualOutageAnalysis2023.03092023.pdf). In this post, we'll cover the main types of data center cooling equipment and why getting that equipment delivered and installed on schedule matters so much. [![Download Dock Scheduling 101: The Ultimate Guide](https://blog.opendock.com/hs-fs/hubfs/DS-eBook-CTA.png?width=1200&height=475&name=DS-eBook-CTA.png)](https://lp.opendock.com/dock-scheduling-ebook?utm_source=blog&utm_medium=organic-content&utm_campaign=data-centers-content-pillar-warehouse-opendock-q2-26&hsLang=en) ## Why Is Cooling One of the Most Complex Phases of a Data Center Build? Cooling has to handle shifting heat loads around the clock while meeting tight limits on energy, water, and carbon. Along with [data center power infrastructure](https://blog.opendock.com/data-center-power?hsLang=en), it's one of the most equipment-heavy and tightly sequenced parts of a build. Variations in air and water flow, fluctuating system demand, and concerns over energy costs, water usage, and carbon footprint all make the choice of cooling equipment critical. ## Types of Data Center Cooling Systems Several types of data center cooling systems serve different functions. Each has pros and cons, and the "best" data center cooling system comes down to your density, energy, and environmental requirements. ### Air-Based Cooling: CRAC/CRAH Units, Hot/Cold Aisle Containment, Raised Floor Systems Air-based systems use CRAC or CRAH units to push chilled air into cold aisles, often through a raised floor. Servers draw that air in, exhaust heated air into hot aisles, and the units pull it back to be cooled again. Containment keeps the hot and cold air streams from mixing. ### Liquid Cooling: Direct-to-Chip, Immersion Cooling, Rear-Door Heat Exchangers Liquid-based systems use coolant to absorb and carry heat away from components. Direct-to-chip systems run coolant through cold plates on processors, immersion cooling submerges hardware in a dielectric fluid, and rear-door heat exchangers cool exhaust air as it leaves the rack. ### Evaporative Cooling for Dry Climates Evaporative cooling passes warm air through wet cooling pads. As the water evaporates, it lowers the air temperature, and that cooled air is circulated through the equipment. ### Hybrid Approaches for AI Workloads Hybrid approaches have emerged largely because of the demand AI is placing on data centers. These systems combine air and liquid cooling: liquid handles the most heat-intensive components, while air cools less critical ones. The result is better energy efficiency for mixed-density environments. | Cooling Type | How It Works | Best Suited For | | --- | --- | --- | | Air-Based | Chilled air cycles through hot/cold aisles | Standard server racks | | Liquid | Coolant absorbs heat directly from components | High-density, high-heat AI hardware | | Evaporative | Water evaporation chills incoming air | Dry climates | | Hybrid | Combines air and liquid by component need | AI workloads with mixed hardware | Whichever system you choose, cost stays front and center. In Uptime Institute's 2024 Global Data Center Survey, [44% of respondents said management was "very concerned" about cost](https://datacenter.uptimeinstitute.com/rs/711-RIA-145/images/2024.GlobalDataCenterSurvey.Report.pdf), the top concern. Forecasting future capacity requirements came next at 30%. Both pressures shape [data center construction costs](https://blog.opendock.com/data-center-construction-costs?hsLang=en) long before the first chiller ships.

Chillers, CRAC units, and liquid cooling infrastructure each carry their own weight, permit, and handling requirements. As more operators adopt prefabricated approaches like [modular data center construction](https://blog.opendock.com/modular-data-center?hsLang=en) to add cooling capacity faster, getting that equipment to site in the right order gets harder. ### Chiller Delivery Challenges: Weight, Permits, Crane Requirements Chillers provide 24/7 cooling, which makes them critical infrastructure. They can weigh several tons, so moving and setting them requires oversize permits, cranes, and rigging crews booked for the same window. On large campuses that challenge multiplies, which is a core part of [hyperscale data center logistics](https://blog.opendock.com/hyperscale-data-center-logistics?hsLang=en). ### CRAC/CRAH Unit Coordination and Batch Scheduling Computer room air conditioners (CRACs) and computer room air handlers (CRAHs) maintain temperature and humidity in the data hall. They often arrive in batches, so deliveries need to be coordinated with installation crews to keep units from sitting in staging or arriving before the space is ready. ### Liquid Cooling Infrastructure: Precision Handling and Hazmat Requirements Liquid cooling infrastructure brings specialized transportation requirements. Some refrigerants and coolants may be classified as hazardous materials, which require particular handling, labeling, and documentation in transit. ### Timing in the Construction Sequence and Weather Dependencies Cooling deliveries have to fit the broader [data center construction timeline](https://blog.opendock.com/data-center-construction-timeline?hsLang=en). Sequencing, site conditions, and weather all affect when heavy equipment can be lifted and set, so delivery windows need room to shift without stalling other trades. ### Dock and Staging Requirements Across Multiple Vendors Transportation and staging for cooling equipment usually span multiple vendors and carriers. Working with experienced [data center logistics companies](https://blog.opendock.com/data-center-logistics-companies?hsLang=en) and keeping every party on a shared schedule helps avoid mishaps and improper handling. ## How Does Dock Scheduling Help Manage Cooling Equipment Deliveries? It gives every vendor a confirmed delivery window, so heavy equipment arrives in sequence instead of all at once. With this many logistical concerns tied to heavy-duty cooling equipment, a shared scheduling system replaces the calls and emails that usually hold a build together. Opendock's [dock scheduling software](https://opendock.com/en/products/dock-scheduling/) sequences inbound deliveries by load type and installation phase, so cooling units, UPS systems, and server hardware don't show up at the wrong dock at the wrong time. When weather or an upstream delay pushes a delivery, appointments can be rescheduled in one place so crews and carriers see the change. [Yard management tools](https://opendock.com/en/products/yard-management/) then help track trailers and staged equipment once cooling units arrive on site. ## Keep Your Cool: Coordinate Deliveries the Right Way with Opendock As AI pushes data centers to run hotter and denser, operators will need to bring the best cooling systems online quickly to keep up with demand. A tool like Opendock helps teams avoid many of the logistical challenges that come with getting cooling equipment to site on time.

Modern data centers mainly use air-based and liquid cooling, with evaporative and hybrid systems filling specific needs. Air cooling suits standard racks, liquid cooling handles high-density AI hardware, evaporative cooling works well in dry climates, and hybrid systems mix air and liquid by component. ### When in the Construction Sequence Should Cooling Equipment Be Delivered? Cooling equipment is typically delivered once the building is enclosed and the pads, supports, and piping it connects to are ready. Exact timing depends on the project's MEP schedule, so align deliveries with crane availability and installation crews rather than ordering everything to arrive at once. ### What Happens If a Chiller Delivery Is Delayed During Construction? A delayed chiller can push back every trade that depends on it. Crane and rigging bookings may need to be rescheduled, crews can sit idle, rental and labor costs rise, and contract penalties may apply depending on who is responsible for the delay.
