Data center cooling has become a major consideration in facility planning. As server density increases, cooling equipment must handle substantial heat loads without creating unnecessary pressure on the building's available space, water supply, or supporting infrastructure. For project developers and facility operators, selecting a chiller is therefore not simply a matter of matching cooling capacity to the expected load. The equipment must also fit the site's physical conditions and long-term operating requirements.
Air-cooled magnetic bearing centrifugal chillers are one option for projects that need high cooling capacity within a relatively compact installation area. The YORK® YDAM Air-cooled Magnetic Bearing Centrifugal Chiller is designed specifically for high-density data center applications. It combines a cooling capacity of 3.5 MW with a stated equipment footprint of 450 square feet and zero on-site water consumption.
These characteristics make it worth considering for data center projects where cooling demand, available space, and water use are important parts of the engineering discussion.
Cooling Capacity Must Match the Density of the Facility
Traditional building cooling requirements and high-density data center cooling requirements are not the same. Office buildings generally have more varied internal heat sources, while data centers concentrate substantial heat generation around servers, networking equipment, power systems, and supporting infrastructure.
As computing capacity grows, the cooling system must remove heat continuously and maintain operating conditions suitable for sensitive electronic equipment. An undersized cooling system can struggle to meet demand during high-load periods. Excessive equipment capacity, on the other hand, may increase initial investment and create challenges when managing partial-load operation.
Capacity planning should begin with the expected IT load and the cooling demand of the complete facility. Engineers also need to consider redundancy requirements, future server expansion, equipment arrangement, and the cooling distribution system.
The YORK® YDAM offers 3.5 megawatts of cooling capacity. For large data center developments, this provides a substantial cooling output within a single equipment platform. Whether that capacity is appropriate for a specific project still depends on the site's calculated cooling load, operating strategy, and required redundancy.
Project teams should avoid selecting equipment based on headline capacity alone. The number of chillers, system arrangement, and available backup capacity all need to be considered together.
Equipment Footprint Matters in High-Density Data Center Projects
Land and building space are valuable resources in data center construction. The site must accommodate server rooms, electrical infrastructure, backup power equipment, cooling distribution systems, maintenance access, and other supporting facilities.
Cooling equipment can occupy a significant part of the available installation area. When several large units are required, their arrangement may influence equipment access, piping routes, structural planning, and the overall site layout.
The YDAM is designed to deliver 3.5 MW of cooling within a stated footprint of 450 square feet. This compact arrangement can be an important consideration for developers working with restricted mechanical plant areas or projects where available space needs to be allocated carefully.
However, equipment footprint should not be confused with the total space required for installation. Engineers still need to account for airflow clearance, service access, electrical connections, piping, lifting arrangements, and local installation requirements.
These details should be checked during the early design stage rather than after the equipment has been selected. A compact chiller can support better space planning, but the complete installation must still provide suitable conditions for operation and maintenance.
Zero On-Site Water Consumption and Cooling Infrastructure
Water availability is another factor that deserves attention during data center planning. Some cooling arrangements rely on water-based heat rejection equipment, which can create additional requirements for water supply, treatment, drainage, and ongoing management.
For facilities located in areas with limited water resources or strict water-use requirements, these considerations can affect both project approval and operating arrangements.
The YORK® YDAM is an air-cooled magnetic bearing centrifugal chiller with zero on-site water consumption as stated in its product information. Its air-cooled design removes the need for on-site cooling water consumption associated with the chiller's heat rejection process.
This feature may be relevant to projects where water access is limited or where developers want to reduce the cooling system's dependence on local water infrastructure.
It is still important to assess the complete facility rather than treating the chiller's water consumption figure as the water footprint of the entire data center. Other systems and building operations may have separate water requirements. The project team should evaluate these independently when preparing its overall resource plan.
Why Magnetic Bearing Centrifugal Technology Deserves Attention
Compressor technology is an important part of chiller selection because it affects the equipment's operating characteristics and maintenance arrangements.
Magnetic bearing centrifugal chillers use magnetic bearing technology to support the rotating shaft without conventional mechanical contact at the bearing interface during normal operation. This is one of the defining features of this equipment category.
For data center operators, the choice of compressor technology should be evaluated alongside cooling capacity, control performance, operating conditions, service requirements, and the manufacturer's technical documentation.
The YDAM is built on the established design and engineering platform of YORK® YVAM. According to its product information, the YDAM extends this platform with greater capacity density in a compact footprint. Its industrial design is intended to address the changing cooling requirements of high-density data center infrastructure.
For procurement teams, the important step is to review the actual technical selection data. Rated cooling capacity, ambient operating conditions, part-load performance, electrical requirements, noise levels, and maintenance procedures should all be confirmed against the project specification.
Air-Cooled Chillers Need Careful Site Evaluation
An air-cooled chiller does not require the same water infrastructure as a water-cooled arrangement, but its installation still depends heavily on the surrounding environment.
Outdoor ambient temperature, airflow conditions, equipment spacing, and potential heat recirculation can influence system operation. Data center developers should also consider local climate conditions and the physical relationship between chillers, buildings, air intakes, and other outdoor equipment.
The equipment layout needs to provide sufficient space for heat rejection and maintenance. Restricted airflow or poorly planned equipment placement can affect operating conditions, even when the selected chiller has adequate nominal capacity.
A complete project assessment should therefore cover:
-
Expected cooling demand and future IT expansion.
-
Local outdoor temperature and installation conditions.
-
Available mechanical plant space and equipment clearance.
-
Electrical supply and connection requirements.
-
Cooling distribution and redundancy arrangements.
-
Maintenance access and service planning.
These factors help determine whether an air-cooled magnetic bearing centrifugal chiller is suitable for the project. They also provide the information needed for accurate equipment selection and system integration.
Selecting a Chiller Supplier for Data Center Projects
Chiller procurement involves more than comparing product specifications. Data center projects often require coordination between the equipment supplier, mechanical contractor, electrical engineering team, consultants, and facility operator.
Technical communication should begin before the final equipment order. The supplier needs sufficient information about the design conditions, cooling load, installation environment, and project requirements to recommend an appropriate configuration.
Buyers should request technical submittals, performance data under the specified operating conditions, dimensional drawings, electrical information, installation guidance, and maintenance documentation. Warranty coverage and after-sales service arrangements should also be clarified.
For projects involving high-capacity cooling equipment, early technical coordination can help reduce installation changes and avoid misunderstandings between the equipment specification and the actual site conditions.

Making the Cooling Decision at the Project Design Stage
High-density data center cooling requires a coordinated approach to capacity, space, water use, and installation conditions. A chiller may offer substantial cooling output, but its suitability depends on how well it fits the facility's overall engineering design.
The YORK® YDAM brings three notable characteristics to this discussion: 3.5 MW of cooling capacity, a stated footprint of 450 square feet, and zero on-site water consumption. For developers evaluating air-cooled magnetic bearing centrifugal chillers, these features provide useful starting points for comparing equipment options.
The final selection should still be based on calculated cooling demand, local environmental conditions, equipment layout, electrical requirements, redundancy planning, and maintenance arrangements. Addressing these points early gives project teams a clearer basis for choosing cooling equipment that fits both the immediate facility requirements and its planned development.
