The standard pump for universal applications and high energy efficiency.
-
Description
The Wilo-Yonos GIGA-N is a pump with high energy efficiency for use in heating, air conditioning and cooling applications in buildings with high delivery heads that require the movement of large volumes of water.
-
Advantages
- Efficient pump thanks to the use of IE4 motors
- Cataphoretic coating of all cast components for high resistance to corrosion and long service life
- Standard dimensions in accordance with EN 733 make the pump universally deployable
- Easy adjustment and operation with Green Button Technology
- Easy maintenance thanks to user-friendly spacer coupling in back pull-out design
- Optional interfaces for connection to building automation using insertable IF modules
-
