Precise AC Units 100-120kW Providing Constant Temperature In Data Centers

Products Introduction

Coolnet PAC units are designed to "provide a constant temperature and humidity specific operating environment for IT equipment and other precision devices." This is a high-precision air conditioner specially designed for computer rooms. In order to ensure good heat dissipation of computers or server chips, application scenarios include computer rooms, laboratories, large medical equipment rooms and other high-precision fields. Its service objects are related equipment that can keep the computer room running continuously: such as IT equipment, power distribution system, power supply equipment, etc. The precision air conditioner has a "constant temperature and humidity" function, and the temperature difference range can be controlled at 0.1 degrees Celsius or even higher. Therefore, precision air conditioners pay more attention to the design of precise control of temperature and humidity in the computer room and timely control of cleanliness.
