Product information
Stratos GIGA 50/1-44/3,2
Your 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
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.
Construction
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
The pumping of heating water (in accordance with VDI 2035), cold water and water-glycol mixtures without abrasive substances in heating, cold water and cooling systems.
