Your advantages
Wilo-SiBoost2.0 Smart Helix VE

Optimal pressure boosting. Intuitive operation.

The Wilo-SiBoost2.0 Smart Helix VE provides reliable water supply in large buildings at all times due to integrated protection functions. These include overload protection, dry-running protection and low-water cut-out switchgear with automatic deactivation. High reliability through integrated protection functions and low water detection (WMS) as well as control via optional interface to the SCADA connection.​

Furthermore, significant energy savings are achieved through pressure-loss-optimised hydraulics as well as optimal load adjustment. ​

The switchgear with colour display provides optimal operating convenience by displaying visualisations and plain text.​


Your advantages

  • Heavy-duty system featuring stainless steel high-pressure multistage centrifugal pumps from the Helix2.0 VE series with an integrated frequency converter with a large control range 
  • Energy savings through IE5 EC motor technology and pressure-loss optimised overall system 
  • Maximum control performance using the SCe2.0 control device with 4.3″ colour display with visualisation and plain text, simple navigation and adjustment using rotary knob
  • Demand-led pressure boosting with the additional control mode p-v and parallel synchronous speed control
  • Integrated protection functions and low-water detection (WMS)
  • Ready for integration into building automation via standard Modbus, BACnet and optional extended communication via Wilo-Gateway
  • All components that come in contact with the fluid are suitable for drinking water
Series description
SiBoost2.0 Smart 2-4 Helix VE 204-5202
