High energy efficiency for cold water applications in large buildings.

Enquire About This Product

Description

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.
Advantages
- IE5 EC motor technology and six integrated control modes (dp-v, dp-c, p-v, p-c, n-const, PID) ensure high energy efficiency.
- Various features – such as dry-running detection, automatic PWM frequency reduction, programmable pump kick and secure-operation mode – provide for a high degree of operational reliability
- Suitable for ambient temperatures of up to 50 °C
- Green Button Technology and clear menu navigation in the colour display enable easy operation
- Proven pump hydraulics made of stainless steel provide a high degree of robustness
- Ready for integration into building automation via analogue or digital interfaces as well as CIF modules
