Kehua Precision Air Conditioning WiseCol-M Series
WiseCol-M Series (7.5kW-20kW)
Air-cooled variable frequency room-level air conditioner
Green, efficient, and energy-saving refrigeration solutions.
Product Introduction
WiseCol-M Series (7.5kW–20kW) air-cooled inverter air conditioners are specifically customized for small and medium-sized computer rooms, communication base stations, and similar scenarios, equipped with intelligent inverter technology. As a vital component of the computer room, the air conditioner is tailored to the equipment environment, featuring constant temperature and humidity control, combined with a design of high airflow and low cooling differential to achieve rapid and uniform heat dissipation. It sets the benchmark for heavy-duty computer room cooling value with long lifespan, low energy consumption, and worry-free maintenance.
