Wilo-Helix VE
Energy-saving and demand-driven high-pressure multistage centrifugal pump for large buildings and other fields of application.
Energy-saving and demand-driven high-pressure multistage centrifugal pump for large buildings and other fields of application.
The Wilo-Helix VE is a vertical high-pressure multistage centrifugal pump with variable speed for cold water applications in large buildings and other fields of application. The pump consists of a drive with an IE5 EC motor, an integrated air-cooled frequency converter and five different control modes. The result is high energy efficiency in both open and closed systems.
The proven stainless-steel pump hydraulics and integrated protective functions such as dry-running detection offer a high level of reliability. Simple integration into the building automation system is possible as a result of analogue and digital interfaces as well as IF modules.
