Overview

Compact, ready-to-connect system for any application that requires system separation by means of an AB-type "free-flow" safety device in accordance with EN 13077
System reliability due to Helix VE series stainless steel high-pressure multistage centrifugal pumps with integrated air-cooled frequency converters
Low life cycle cost thanks to the new Helix design.
User-friendly display with green button technology and full-text menu
Plug-in IF modules for fast communication with building management systems

Type

Water supply unit with system separator and speed-controlled standard-suction high-pressure multistage centrifugal pump

Application

Fully automatic water supply and pressure boosting in residential, office and administration buildings, hotels, hospitals, shopping centres and various industrial facilities
