Special features/product 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

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 double pump version.

Design type

High efficiency inline double 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.
