Wilo Stratos

* Models with PN10 threaded connection. For other models, please consult.

Special features

• Energy savings thanks to superior system efficiency with Q-Limit function (flow limitation)
• Improved energy efficiency index EEI≤0.20 for all single pumps
• Optimized screen for better reading and handling
• Installation in tight spaces thanks to the compact design and freely positionable liquid crystal display
• Modular concept for connecting all conventional bus systems (e.g. Modbus, BACnet, CAN, LON, PLR)
• Quality and reliability guaranteed

Guy

Wet rotor circulator pump with threaded or flanged connection, EC motor with automatic power adaptation

Application

All hot water heating systems, air conditioning systems, closed cooling circuits, and industrial circulation systems.
