- Improved Energy Efficiency Index (EEI) ≤ 0.20 for all single pumps
- Enhanced display for better readability and ease of operation
- Space-saving installation thanks to compact design and variable-orientation LC display
- Modular concept for connection of all conventional bus systems (e.g. Modbus, BACnet, CAN, LON and PLR)
- Tried-and-tested quality and reliability
Construction
Glandless circulator with threaded connection or flange connection, EC motor with automatic power adjustment.
Application
