WEFTEC®.06 water and oil), by far the most common cooling method is fan operated forced air cooling shown in Figure 8. Local environmental and safety conditions will determine the cooling method most acceptable for reliable equipment life. Figure 8 Typical SCR (Thyristor) Rectifier Cooling Fan Arrangement Rectifier units are designed to operate at maximum ambient temperatures of 105 to 125oF (40 to 50oC) to assure that control and power electronics can survive possible installed environmental service stresses. All DC power systems are designed around these temperatures, unless more stringent specifications are necessary resulting from local conditions. Maintenance - While minimal maintenance is required for water and oil cooled systems, regular oil and closed loop cooling media inspections must be performed. Each manufacturer should provide inspection guidelines to assure that the inspector will detect problems before they become equipment failure incidents. Forced air cooled systems require; quarterly cooling fan and motor inspection; quarterly filter screen cleaning; semi-annual wire and cable termination connection inspection and DC device and transformer cleaning. It is best to use a compressed air nozzle for cleaning transformers and DC devices. Water Softening - The water softener’s use in on-site sodium hypochlorite generation systems is prevention of calcium and magnesium hardness salts from depositing on the negatively charged cathodic electrode. As will be discussed later, systems can be operated without softened water, however, the potential for electrode damage becomes highly probable unless frequent stringent maintenance procedures are followed. Water softening via ion exchange utilizes the replacement of calcium and magnesium ions in the water by an equivalent number of sodium ions. This system eliminates the undesirable characteristic of calcarious deposits because sodium salts do not form hardness type scales on the Copyright ©2006 Water Environment Foundation.
