3-6 Water Connection Sizing Considerations

Important!

∙Run all external chilled water connections with adequate size to the process.

∙Provide the largest possible openings and passages for the flow of chilled water through platens, dies, molds, or other pieces of equipment.

∙Minimum external pressure drop is critical for proper operation.

3-7 Galvanic Corrosion Considerations

Water circuit piping components are primarily ferrous (iron) and react electro-chemically with non-ferrous metallic materials such as copper. Some water has dissolved minerals that will greatly accelerate the reaction between dissimilar metals.

Use PVC or ferrous piping to minimize galvanic action. If piping must be copper, use dielectric unions at the chiller.

3-8 Water Treatment Considerations

Water treatment is important in any piping system. In some locations, raw water may be used in the system without problem; in other locations, it will result in large deposits of scale and corrosion.

Sterling offers a complete line of water treatment equipment. Contact your Sterling sales representative for water testing and treatment options.

3-9 Making Water-Cooled Condenser Connections

SSC Series water-cooled chilling stations use city or tower water as a cooling medium. All external condenser supply and discharge piping and connections should be of adequate size.
