Air-cooled Close Control Air Conditioner

The Gree JKF series close control air conditioner is designed specifically for environments housing computers, equipment, servers, and other sensitive electronics. This unit features an advanced design structure, coupled with powerful and precise logic control for optimal performance. It undergoes rigorous testing in high-standard laboratories and is subjected to strict quality management during production. As a result, it offers precise control of ambient temperature and humidity, ensuring long-term stability and continuous operation. This makes it an ideal solution for critical environments in transportation, power, IT, and other industries. The cooling capacity of the R410A models ranges from 5kW to 40kW, and each unit is equipped with a reserved long-distance monitoring function. Up to 253 modules can be combined for operation, offering a scalable solution for large-scale requirements.
