Monobloc machinery used to cool or heat the water, as needed, through heat exchange with the refrigerant. The water coming out of these units will subsequently fuelled the terminal unit (fan coil system or on the floor), located within the premises, for the air conditioning of the same.
The water coolers, which can either be cooled with outdoor air and with water from the well or cooling tower, can also be used on industrial applications as for cooling machine tools, presses, etc..
