Highly energy-efficient and easy to operate, suitable for cold water applications.
The Wilo-Helix2.0-VE is a versatile, next-generation vertical multistage cold water pump. Its frequency converter offers six control modes and, combined with an IE5 EC motor, adapts to various pressure and volume flow conditions, ensuring high energy efficiency in both closed and open systems. The proven, reliable Helix stainless steel hydraulics also ensure high operational reliability.
A color display with clear, easy-to-read menu navigation, combined with reliable Green Button Technology, makes commissioning and operation simple. Integration into building automation systems is easily achieved via analog and digital interfaces as well as CIF modules.
