WILO STRATOS GIGA high-efficiency pump

Your advantages

• Innovative high-efficiency pump for maximum overall efficiency levels

• High-efficiency EC motor with efficiency class IE5 in accordance with IEC 60034-30-2

• Optional interfaces for connection to building automation using insertable IF modules

Maximum performance at the highest levels of energy efficiency.

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.

Construction

High-efficiency in-line pump with EC motor and electronic power adjustment in glanded pump design. 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.
