3-3 Process Water Connections

All of our portable chillers have two chilled water connections. The chilled water supply, labeled “To Process” is the outlet for the chilled water leading to the process being cooled. The chilled water return, labeled “From Process” is the inlet leading from the process back into the chiller to be cooled and re-circulated.

All external chilled water connections should be run full size to the process. Flow and pressure information is available on pages 58-61 in the Appendix. The largest possible openings and passages should be provided for the flow of chilled water through platens, dies, molds, or other pieces of equipment.

Note: Be sure to reduce external pressure drop as much as possible by generously sizing piping and tooling water passageways.

3-4 Bypass Valve Considerations

Our portable chillers have a spring-loaded bypass valve. If the chilled water shut-off valves are inadvertently closed while the chiller is running, the factory-set bypass valve opens and allows a small amount of water to flow through the chiller. This action protects the chiller from freeze-up and allows the other cutout devices to shut down the chiller. The bypass valve is not intended to provide continuous full bypass flow.

Caution! Do not attempt to adjust or otherwise tamper with the bypass valve. Your warranty will be voided.

3-5 Galvanic Corrosion Considerations

The materials used in the water circuit piping of these chillers are non-ferrous and react electro-chemically with ferrous metallic materials. Some water has dissolved minerals that greatly accelerate the reaction between dissimilar metals.

PVC or non-ferrous piping is recommended to reduce galvanic action. If iron piping must be used, use dielectric unions at the chiller.

3-6 Water Treatment Considerations

Water treatment is an integral part of the system. In some locations, water may cause large deposits of scale, erosion, algae, and/or corrosion.

Note: The use of poor quality water may result in inefficient operation, heat exchanger damage, and pump seal damage. Consult a qualified water treatment specialist to determine whether treatment is needed.
