Wilo-Comfort-Vario COR-1 MHIE...-GE

Series description

Your advantages

  • Sturdy system due to MHIE series stainless steel high-pressure multistage centrifugal pumps with air-cooled integrated frequency converter
  • Frequency converter with superproportionally large control range
  • Integrated full motor protection via PTC
  • Integrated dry-running detection with automatic cut-out in event of low water via performance characteristics of the motor control electronics

Construction

Water-supply unit with a non-self-priming high-pressure multistage centrifugal pump and integrated speed control

Application

  • Fully automatic water supply and pressure boosting in residential, commercial and public buildings, hotels, hospitals, department stores and for industrial systems.
  • Pumping of drinking water and process water, cooling water, fire water (apart from fire-extinguishing systems in accordance with DIN 14462 and with the approval of the local fire safety authorities) or other types of industrial water that do not attack the materials either chemically or mechanically and do not contain abrasive or long-fibre constituents.
