Closed Cooling Water System Treatment and Monitoring

Nov 01, 2018The aspect that makes closed cooling so suitable for many applications is that the chemistry can be carefully controlled. But, neglect of water treatment and monitoring can lead to corrosion and fouling, which may be very troublesome. For example, a common type of closed cooler is the plate-and-frame (PF) heat exchanger (see Fig. 2).
