Wilo-Helix2.0-VE
High energy efficiency for cold water applications in large buildings.
High energy efficiency for cold water applications in large buildings.
Wilo-Helix2.0-VE is the new generation of vertical multistage pumps for cold-water applications in large buildings. The built-in frequency converter , in conjunction with the control functions and IE5 EC motor drive, provides optimum adaptation to a wide range of pressure conditions and flow rates. The result is high energy efficiency in both closed and open systems. The proven Helix stainless steel hydraulics also offers high reliability. A colour display with clear menu navigation and the familiar Green Button Technology enable easy commissioning and operation of the pump. It can be very easily integrated into building automation via analogue and digital interfaces as well as CIF modules.
