Series description

Special features/product advantages

  • Rapid, easy installation with pre-installed system. Troubleshooting minimised as a result.
  • Energy-saving: Operation in partial load range in accordance with current demand.
  • Reliable system thanks to intermatched components.
  • Compact design, good accessibility of all components.
  • Everything from a single source. Less need for clarification at time of procurement.

Design type

High-efficiency, fully automatic, ready for connection multi-pump system for the implementation of larger volume flows in heating, cold water and cooling systems. 3 to 4 parallel-switched, electronically controlled inline pumps in glanded design of the series VeroLine–IP-E or CronoLine-IL-E. One pump in each case as standby pump. Including Smart Controller SCe.

Application

For pumping heating water (in accordance with VDI 2035), water-glycol mixtures and cooling and cold water without abrasive substances in heating, cold water and cooling water systems
