Wilo-Comfort COR Helix VE

Pressure boosting system with 2 to 4 parallel-switched, non-self-priming stainless steel high-pressure multistage centrifugal pumps with speed-controlled motors

  • Fully automatic water supply and pressure boosting in residential, commercial and public buildings, hotels, hospitals, department stores and for industrial systems.
  • Pumping of potable water and process water, cooling water, water for fire-fighting or other water mixtures that do not chemically or mechanically attack the materials used and do not contain abrasive or long-fibre constituents
Special features/Product advantages
  • Compact system with outstanding price/performance ratio due to MHIE series stainless steel high-pressure multistage centrifugal pumps with integrated air-cooled frequency converters
  • Superproportionally large control range
  • Integrated full motor protection via PTC
  • Integrated dry-running detection with automatic deactivation in the event of low water through the use of the performance characteristics of the motor control electronics
