Secondary Variable Pumping System
Secondary Variable Pumping System
Secondary variable pumping systems are ideal for large interchange metro stations and depot facilities where multiple zones require independent temperature control. Primary pumps maintain stable chiller flow, while secondary pumps distribute chilled water across platforms, ticketing halls, retail areas, and control rooms.
This hydraulic separation enhances operational stability and allows flexible zoning. In extensive metro networks, secondary systems improve scalability and reduce pumping energy during partial load conditions.
