Abstract
A cooling-tower water re-circulating system 1 for maintaining water cool for use in an air-conditioning system 2 has a purification unit incorporating a silver and copper ion generator 17 whose ion output is controlled by control unit 12 in accordance with the measured ion content in the water determined by ion sensors 14, 15 and 16 and also with other operations of the system such as draining the system when the detected impurity level exceeds a threshold. In this way, efficient and effective purification with continual monitoring is achieved. The ion sensors 14, 15, 16 each comprise an elongate body of material including platinum which is immersed in the water to be tested whereby the ion content of the water is derived from the charge detected in the body. <IMAGE>
