Data Center Cooling

Servers, computers, and networking equipment in data centers and AI computing centers require enormous amounts of energy to run, and in the process, they generate large amounts of heat. Left unchecked, equipment can overheat or become damaged, risking data processing delays, loss of stored data, and unplanned downtime.

Data centers can consume up to 50 times more energy than a typical commercial office building, so it's critical to install HVAC and cooling fan solutions specifically designed for data center applications. Pelonis Technologies offers a comprehensive selection of fans for keeping computer equipment cool, including energy-efficient fans for ventilation and exhaust as well as AC and DC fan blowers.

Our Data Center Cooling Solutions

Cooling fans help maintain optimal temperatures and airflow in hot spots and keep chilled air circulating throughout aisles and all around equipment racks. Pelonis Technologies' cooling products include state-of-the-art backward curved centrifugal fans and axial fans that help keep data centers running smoothly.

AC Centrifugal Fans

AC centrifugal fans operate on the principles of centrifugal force, producing higher-pressure airflow and better resistance. Using a drum-shaped impeller design, the fan draws in air along its entry axis. Forward curved blades drive the air outward, perpendicular to this axis along the fan's outer circumference.

By producing high pressure and consistent airflow, centrifugal fans create sufficient directional airflow for applications like HVAC cooling and drying, blowing away debris, fume exhaust, dust collection, and other ducted air-moving systems. AC centrifugal fans are an especially effective solution for cooling data center electronics and equipment.

DC Centrifugal Fans

DC centrifugal fans also use centrifugal force to create high-pressure airflow, but with a more compact profile for integrations into space-constrained applications. They also consume less power while maintaining efficient performance. DC centrifugal fans are easy to install and use in a wide range of forced-air cooling applications, particularly server racks and industrial equipment with unique installation requirements.

Backward Curved Centrifugal Fans

Backward curved centrifugal fans (AC, DC) pull in air with an impeller, then expel it in a direction perpendicular to the direction of intake. They create a stream of high-pressure air and are a good choice for directing air to a specific area to improve circulation or airflow.

These fans are available with AC or DC power supplies and have these features:

Efficient cooling at low speeds
Airflow control
Air movement
Low energy consumption design
Quiet operation

AC Axial Fans

One of the most popular and enduring options, AC axial fans work by drawing in air and expelling it in the same direction, parallel to the entry axis. This design supports high airflow rates at low pressures.

Their efficient design makes AC axial fans suitable for large settings that depend on high airflow volumes with minimal power input, such as industrial facilities and large AI data centers. AC axial fans are also easy to assemble and operate with DC power sources like batteries or solar panels. In data centers, these fans help eliminate hot spots and maintain operations regardless of grid-related power fluctuations.

DC Axial Fans

DC axial fans are appropriate where standard AC power is limited, such as in harsh outdoor environments. Pelonis Technologies’ DC axial fans are rated for IP51, IP54, IP56, or IP67 moisture and dust protection. Our DC axial fans also employ a brushless motor design to reduce thermal load and extend bearing life. Insulated motors power the ball bearings and sleeves.

The innovative multi-blade impeller contributes to greater airflow performance, and its Intelligent Motion Controls feature full-wave, in-board circuitry to adapt to changing air movements and voltage fluctuations. With programmable controls, our DC axial fans offer enhanced protection and optimal performance.

We test each DC axial fan for minimal noise production under even high-pressure, high-airflow conditions. Every model meets RoHS compliance standards and requirements for withstanding mechanical vibrations, shock, humidity, and thermal cycling.

The Importance of Keeping Data Centers Cool

Data centers are essential in the modern digital world, especially with the expansion of AI and the massive computing resources it entails. These facilities contain storage subsystems, network equipment, and powerful servers that process data and power online transactions at high speeds and volumes. Each computer generates heat from its microprocessor and circuitry, and that heat is compounded when multiple powerful computers are housed together.

Temperatures can build up quickly, and if proper cooling systems are not in place, there are numerous potential risks, such as:

Equipment failure or damage

Reduced processing speeds

Data loss or file corruption

Equipment or online application downtime

Incomplete or failed transactions

Efficient cooling prevents costly disruptions to service and maintains optimal server performance. In addition to large-scale air conditioning, chiller systems, and heat exchangers, fans and blowers are important tools for targeted temperature and airflow control.
