    information

    Brief Introduction
    FREECOOL-AD, an adiabatic evaporation cooling unit, is designed for small/medium data center or electronic equipment room. Direct free cooling will be used when outdoor temperature is low; if ambient temperature rises, adiabatic mode will be used. Ambient air will blow through the built-in pad saturated with water, evaporating water by air flow.
    By using the FREECOOL-AD unit, the running hours of other air conditioning units can be highly reduced, achieving power energy saving around 30%~90%.
    The FREECOOL-AD unit using EC fan can adjust the air volume automatically according to the temperature difference with the lowest power consumption.FREECOOL-AD realizes easy installation and convenient maintenance without refrigeration system. The unit only needs to connect the inlet and outlet water pipe on the work site. Down flow and up flow units using the same structure, offering more flexibility for different customers.
