The Wilo-COR-Helix-EXCEL pressure boosting system is predominantly used for cold water supply in building services engineering and in industrial applications. It combines EC motor technology, innovative pump hydraulics and a dedicated electronic system control. This concept enables a sustainable reduction of life cycle costs and energy consumption. Its modular construction allows the system to be extended to two to four pumps as required. The cover contributes to a fully integrated system appearance and protects the hydraulic installation from soiling or misuse. All user interfaces are easily accessible and subdivided into two access levels.
