It is possible for all LKV type compressors to be made as water cooled. In compressors with this optional feature, using air/water and oil/water exchangers the cooling of air and oil is provided. In this system applied by using body / tube type or plate type heat exchangers, the compressors can be far more quiet as there are no fans. Moreover, as the temperature changes of water are lower in comparison with air, water cooled compressors can work more efficiently even in hot, tropical countries. Cooling tower or chiller is used to cool the water. Actuated valves and flow switches are used for the control of water flow in the compressor water circuit. With the integration to the air/water and air/oil production processes, it can become a heat exchanger.
