In order to offer the best possible space utilization, and to accommodate the potentially rapid expansion of new IT equipment, modern data centers have implemented a high-density model, based primarily on blade server technology. This model requires a higher power supply density, and can thereby create more significant problems with heat dissipation. In order to address these issues, round-the-clock air conditioning is sometimes deployed as a cooling system solution. However, the expense of using this method for data center cooling can end up accounting for up to 45% of the total electricity expenses incurred by the data center. With this in mind, heat dissipation and electricity expenses are important indices against which operational expenditures of the data center can be measured.
As a leading global manufacturer of fans and a specialist in power management, Delta Electronics was perfectly positioned to develop Delta InfraSuite Precision Cooling solutions in order to provide practical, optimized, innovative methods for data center cooling. Delta’s precision cooling enthalpy laboratory carefully verifies cooling system performance and reliability during the engineering development and design process to ensure high product performance.
Specialized forms of air conditioning and temperature control have been developed to cater to the unique cooling system needs of contemporary data centers. Traditional precision air conditioning is not appropriate in many cases as a data center cooling system. This type of air conditioning cannot provide adequate heat removal for data centers due to the problems of uneven heat distribution, load variations experienced during peak and off-peak periods, and high power density. An optimal data center cooling system must accommodate for each of these factors. Instead of traditional precision air conditioning methods, Delta InfraSuite Precision Cooling solutions employ either chilled water or refrigerant types to remove the heat produced by the hardware within the data center.
Cooling units can be installed in a modular rack design, which enables quick configuration and is readily expandable by load. Data center cooling by water is safe for the equipment it protects due in part to built-in leakage detectors, which can display leaks and offer alerts in a timely manner. With manual dehumidification capacity, Delta’s data center cooling system offers a rapid and precise means of adjusting the level of moisture within the air, and keeping humidity levels within the ideal range required by the data center equipment.
Introduction
With the increasing demand for high performance computing in data centers and the continuous advancement of IT equipment process technology, high thermal design power chips require a new advanced cooling technology. Delta’s two-phase immersion liquid cooling has emerged to meet these new requirements.
Integrating new technology and an innovative mechanism design, Delta’s two-phase process directly immerses electronic parts and equipment in non-conductive coolant, and removes heat through the phase change of the coolant. This improves heat dissipation efficiency by reducing the heat exchange process, which is significantly more efficient than traditional air cooling, reducing energy consumption by 84%.

The Delta CoolDoor is a rear door cooling unit with EC fans designed for high power density racks and offering high reliability and energy efficiency. Combined with Delta’s CDU or chiller, CoolDoor removes heat at its source without hot air going into the room. CoolDoor is compatible with various racks through its connect duct. It doesn’t need an added footprint and raised floor to save valuable space and reduce the CAPEX of your data center. CoolDoor features a turbo boost function that helps to dissipate heat from an adjacent rack that may have issues. It is also equipped with a leakage detection function that provides an alarm notification to the user or automatically shuts down the water supply when a leakage is detected.
Delta is pleased to customize your CoolDoor units to provide the optimal products for your data center.

For data centers with raised floors, the space beneath the floors is usually used as the cold aisle to deliver cold air to the IT racks. In data centers with this type of architecture, the amount of cold air that can be received by each IT rack depends on the static pressure of the cold aisle, the opening areas on floors as well as the suction capability of the racks. If any of these three criteria are insufficient, the rack will face the problem of insufficient supply of cold air and result in overheating.
The Delta ADU provides data centers with a simple solution for hot spots at the end of an aisle or for overheated high power density racks. Delta’s ADU installs under the original openings of a raised floor where it detects the temperature inside a target rack or hot spot. The ADU automatically adjusts the rotation speed of its electronically commutated (EC) fan to provide the cool air needed by the target rack or hot spots.
Applications:
- High power density rack area
- Environment that requires precise environmental control
features
High Availability
- Maximum airflow above 1000 CFM.
- Inherent redundancy design if a fan malfunctions, other fans automatically increase in speed to make up the required airflow.
- The EC fan uses internal temperature data feedback of the target rack to automatically adjust fan speed and achieve the required rack temperature.
- Installs directly under raised floors with common openings – no need for special raised floors.
- Four dry contact outputs and one input for administrators to monitor and control.
