Precision Air Conditioners

CMA Room-Based Air-cooled Air Conditioner provides precise temperature and humidity control for large and medium-sized data centers. It uses efficient compressors and is equipped with EC centrifugal fans to meet the continuous operation requirements of 24x7. It is an ideal choice for green and energy-efficient data centers and various electronic equipment rooms. 

CRAC DX unit utilizes the direct expansion cooling technology, where the refrigerant is compressed by a compressor into high-temperature and high-pressure gas. Then it expands through an expansion valve to become low-temperature and low-pressure gas, thereby achieving the desired cooling effect.It uses efficient compressors and is equipped with EC centrifugal fans to meet the continuous operation requirements 24x7. It is an ideal choice for green and energy-efficient data centers and various electronic equipment rooms. 

The Inrow Cooling Chilled Water System provides localized cooling by installing cooling units directly near the equipment, effectively reducing the temperature. The system offers advantages such as higher cooling efficiency and precision, eliminating energy losses from long-distance air distribution, and the ability to scale and adjust according to the cooling needs of different equipment.

CRA Row-Based Air-Cooled Aircon is installed close to heat sources, minimizing the length of the cold airflow path and accurately handling the sensible heat generated by servers.

The CMC Room-Level Chilled Water Precision air conditioner is a product developed further based on the CMA room-level air conditioner. It is typically used in conjunction with chillers, water pumps, and chilled water pipelines to form a refrigeration system. It has the characteristics of high refrigeration efficiency and significant energy savings.

The CMF Room-Based Free-Cooling Air Conditioner (Refrigerant pump) can use an atmospheric natural cold source for cooling the computer. The natural cooling efficiency of the CMF refrigerant pump is 10 times that of mechanical refrigeration mode at low ambient, which effectively reduces the PUE value of the room. 

CRF, as well as Row-Based Aircon (Refrigerant Pump), inter-row level air conditioning for machine rooms, utilizes natural cold sources from the atmosphere for room cooling. It is installed in close proximity to heat sources, minimizing the length of the cold airflow path and accurately handling the sensible heat generated by servers.

The CRC Row-Based Air Conditioner (Chilled water), while maintaining the characteristics of close proximity to heat sources and precise cooling, is more suitable for scenarios with limited on-site installation (no need to install a separate outdoor unit), supporting the continuous development of green data centers.

HDA Precision aircon is designed to provide a comprehensive cooling solution for medium to low-heat-density data center rooms. The unit features "high-efficiency fans" combined with adjustable air guide grids, employing stepless speed control design. The overall energy efficiency ratio can reach up to 3.6, far exceeding the national first-level energy efficiency standards, positioning it at an industry-leading level.

This type of precision aircon is in our CNA Dual-Engine Series and features two independent refrigeration cycles. These systems offer flexible switching, and autonomous rotation, and serve as backups for each other. They provide professional advantages with high reliability and energy efficiency, capable of meeting the high cooling demands of continuous operation in data center environments.

Rack-mounted air conditioning unit is a cabinet-level temperature control product designed specifically for high-density data centers. It is closely attached to the rack of the server cabinets, allowing for precise handling of high sensible heat generated by the servers within the cabinets. This effectively prevents the occurrence of localized hot spots and contributes to the continuous development of green data centers.

CSA air-cooled precision air conditioner for data centers uses advanced design concepts and efficient EC centrifugal fans. It has been tested and verified on the CNAS test platform, showing significant features of long-lasting energy efficiency and stable operation. With a cooling capacity of 8-30kW, both fixed-frequency and variable-frequency units can achieve an annual energy efficiency ratio of ≥4.0. This means that the air conditioner efficiently utilizes energy, saving consumption and reducing environmental impact. It also features high-efficiency EC centrifugal fans for precise airflow control and lower power consumption.

The Heat Pipe Air Conditioning Unit is an energy-efficient air conditioning system designed to provide precise temperature and humidity control for facility rooms. It utilizes a high-efficiency refrigeration system that leverages natural cooling sources and meets the continuous 24/7 operational requirements. It is an ideal choice for green data centers and various electronic equipment rooms.

JG Cabinet Air Conditioner is an AC-integrated cabinet air conditioner, specially designed for cooling high-heat cabinets. Adopting compressor cooling, independent circulation of internal and external air, completely sealed, effectively ensuring the service life and work stability of electronic components.
