Hydraulic water station for combination with water-cooled water-water cooler and dry cooler. It is suitable for systems in industrial or commercial applications where cooling is required all year round.
When the outdoor air temperature is greater than the system water return temperature, the cooling capacity is provided by the chiller. The WST hydraulic station manages the dry cooler by regulating the speed of the dry cooler fans, according to the condensing pressure of the cooler. When the ambient temperature is lower, the WST turns off the chiller, using the water from the dry cooler to cool the system water through the free-cooling exchanger.
