	A high quality water cooling system with total heat power dissipation of 500 kW has been built and successfully used for a 100 MeV high intensity Cyclotron. The main features of this system are high water quality with specific conductivity bellow 0.5 μS/cm, high cooling water temperature stability better than ±0.1°C for long time operation and much electric power-saving in comparing with classical design. For some special usages, such as high beam power target and vacuum helium compressor, they all are well treated and reasonably separated from the main cooling system. There are totally 108 distributed water branches together for different sub-equipments of the cyclotron. At each branch, there are one water flow switch for safe interlock, one flow meter for monitoring, one temperature sensor for remote diagnostics. The water cooling system is under automatic control with PLC, and its operation status and all parameters can be remotely monitored from the control room. All of the involved equipments can be switched on/off by one key, no on-duty staff is needed at normal conditions. This system has been put into commissioning for two years and proved successful and reliable.

A high quality water cooling system with total heat power dissipation of 500 kW has been built and successfully used for a 100 MeV high intensity Cyclotron. The main features of this system are high water quality with specific conductivity bellow 0.5 μS/cm, high cooling water temperature stability better than ±0.1°C for long time operation and much electric power-saving in comparing with classical design. For some special usages, such as high beam power target and vacuum helium compressor, they all are well treated and reasonably separated from the main cooling system. There are totally 108 distributed water branches together for different sub-equipments of the cyclotron. At each branch, there are one water flow switch for safe interlock, one flow meter for monitoring, one temperature sensor for remote diagnostics. The water cooling system is under automatic control with PLC, and its operation status and all parameters can be remotely monitored from the control room. All of the involved equipments can be switched on/off by one key, no on-duty staff is needed at normal conditions. This system has been put into commissioning for two years and proved successful and reliable.
