  • Description

    The Wilo-Stratos GIGA is the ideal high-efficiency pump for use in heating, air conditioning and cooling applications in buildings where large volumes of water have to be pumped to great delivery heights. Wilo-Stratos GIGA offers ever greater operational reliability with the standby pump in the twin-head pump version.

  • Advantages
    • Innovative high-efficiency pump for maximum overall efficiency levels
    • High-efficiency EC motor with efficiency class IE5 according to IEC 60034-30-2
    • Highest possible operational reliability thanks to standby pump
    • Optional interfaces for connection to building automation using insertable IF modules
  • Technical Features

    Design

    High-efficiency in-line twin-head pump with EC motor and electronic power adjustment in glanded pump construction. Version as single-stage low-pressure centrifugal pump with flange connection and mechanical seal.

     

    Application
    • Pumping of heating water (acc. to VDI 2035), chilled water and water/glycol mixtures without abrasive substances in heating, chilled water and cooling systems.
