冷却水用グリコール水手動

Résumé
The Wilo-Stratos GIGA B 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 heads.

Principaux avantages

• Innovative, high-efficiency pump for maximum overall efficiency with principal dimensions in accordance with EN 733
• High-efficiency EC motor with efficiency class IE5 in accordance with IEC 60034-30-2
• Integrated pump support feet and optional supporting block allow for easy installation
• Optional interfaces for bus communication using plug-in IF-Modules

Design
High-efficiency close-coupled end suction pump with IE5 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), chilled water and water-glycol mixtures without abrasive substances in heating, chilled water and cooling systems.
